Montevideo Butterfly Garden Design

***This Blog Post is a work in progress. I will update it continuously as I learn more. 
Voy a traducir este artículo al español.

Acknowledgment: The information in this article comes from what I have learned over the last 9 years, studying with Tree Stewards of Arlington and Alexandria and Taller en Verde in Montevideo, meeting and studying the work of Doug Tallamy of University of Delaware, and meeting and studying the work of Gabriela Bentancur in Montevideo. I've also spent countless hours scouring the internet for information on butterfly/plant interactions, and planting butterfly host and nectar plants and observing the results. 

I'm currently living in Uruguay. I'm studying Sustainable Landscape Design with Lucia Ifran. The class is called Taller en Verde, a class about designing gardens with native plants.  While a vast majority of Uruguay's land is devoted to pasture for cattle, cash crops like sorghum and agroforestry for paper pulp, a growing number of landowners are realizing the role native plants play in ecosystem and biodiversity support. The plant nurseries are slow to catch on, as usual, and so they are still carrying the usual Chinese, European, African and Australian exotics that perform so well here. As I learn of nurseries here in Uruguay that supply natives, I'll post them below.

My main goals in garden design are biodiversity support and greenhouse gas mitigation for climate stabilization. Greenhouse gases, especially carbon dioxide, are absorbed by plants. The advantage of large woody plants like trees and shrubs is that they take up more carbon dioxide and hold it in the form of wood. The longer the wood remains in the form of wood, the longer the carbon dioxide is kept out of the atmosphere. When it is chipped, burned and decomposed, it releases its carbon dioxide back into the atmosphere. When I learn about large, long-life trees that are also host and food plants for wildlife, those are the ones I most promote by planting them myself and encouraging others to plant them as well. 

Whenever I move to a new country, every three or four years, I start learning about the local native plants. Even if I don't have a garden, as was the case for four years in Rome, I learn as much as I can about the native plants, butterflies and birds so I can talk to people about the value of choosing native plants for garden design.

For the past year and a half, I've been studying the plants and butterflies of Uruguay. I have a large garden to experiment with. Currently I'm planting different kinds of passion flower to host the Gulf Fritillaries.  I can't get enough of the local small, tender-leafed local variety, because it's not for sale in the nurseries, so I've planted some of the larger leafed Brazilian passion flower next to it.  The local variety is loaded with eggs and caterpillars, but they are about to eat it all up.  I've only seen one egg on the Brazilian plant, and none of the caterpillars have moved over to it yet. Maybe they will migrate over in desperation in the near future. Update: there are now many eggs and and caterpillars on the Brazilian Maracuja' vines. 

The main purpose of this article is to share what I've learned about gardening for biodiversity and climate in Uruguay, and encourage others who have a ranch, garden, patio, balcony or even just a window box, to plant as many native plants as possible. 

When you plant natives for wildlife, don't forget that if you plant it, they will come.  And they will eat.  The appearance of caterpillars munching on your leaves is a sign that you've chosen the right plant for the right place. If they look like they're going to eat the whole plant, buy more plants.

Try to keep your garden a little messy.  Remember that the insects and birds you're supporting use the leaves, grass and shrubs as food and shelter. Don't mow the grass too often, and let the leaves remain under trees and shrubs.  If you rake and toss the leaves, you'll be throwing away the developing butterfly chrysalises you are nurturing.


Butterflies of Montevideo and their host plants

The Gulf FritillaryAgraulis vanillae

Espejitos on Lantana

Locally called "Espejitos", this is one of the most common butterflies in Montevideo.  Their only caterpillar host plants are species in the Passiflora genus. Each regional version of this butterfly tends to prefer its local species of Passiflora, whether it be Mburucuya in Uruguay (Passiflora caerulea), Maracuja' in Brazil or the Maypop purple passionflower in Florida. The adult butterflies will take nectar from Lantana flowers.  Therefore, the best way to attract the Gulf Fritillary and support its life cycle, is to plant a lot of the local Passiflora vine, and several Lantana shrubs nearby. My gardener doesn't want the vine growing on the front fence, so he's constructing bamboo pyramid structures to support the vines away from the fence.
According to Mariposas de Uruguay by Gabriela Bentancur Viglione, the Passiflora is the host plant for several butterfly species in the Nymphalidae family here in Montevideo, such as the Hortensia, with brown and yellow spots, and the Juno and Julia, with similar orange coloring to the Espejitos, but with black stripes instead of spots. Erato is another butterfly in Uruguay dependent on the Passiflora. The Erato is black with two red splotches and two white stripes.
The favorite sources of nectar for Espejitos are Verbena and Lantana. 

Southern Monarch, Danaus erippus and Emperatriz, Danaus eresimus 

Southern Monarch Source: Wikipedia

Both of these are cousins of the North American Monarch, Danaus plexippus, and like the Monarch, their caterpillars feed exclusively on milkweed species, Asclepias sp. The chemicals in the milkweed are what give Monarchs their superpower of being poisonous to birds who ignore the warning of their coloration and try to eat them. In Montevideo, the local milkweed is hard to find, and not usually available for sale. The butterflies have adapted to the alien invasive milkweed from Africa, the Asclepias physocarpa or "Globitos", named for its little green balloon seed pod.  You can plant these in your garden if you find some.  They spread easily from seed once they get started. My teacher says they're terribly invasive in Uruguay and she has some trepidation in recommending them as Monarch host plant. She says if you must plant it, dispose of most of the seed pods and only keep one or two to propagate next year's crop.  But she says the best thing to do is find the local milkweeds, Asclepias mellodora, "Yerba de la Vibora" and Asclepias curassavica, "Flor de Sangre". I haven't found any yet.

Peacock, Junonia genoveva
Peacock Source: Wikipedia
The local name for the Peacock butterfly is "Pavo Real".  It is similar to the Tropical Buckeye and the Mangrove Buckeye. It thrives in uncut grass and the weeds that grow in it.  Try to leave a large area of your lawn uncut. Divide it into two patches. Alternate mowing one patch each month. That way each patch gets cut only once every two months. That gives the butterflies enough time to complete their life cycle of laying eggs, hatching, caterpillar, chrysalis and then emerging as butterfly. Some landscape management guidelines recommend only mowing once, in late fall, using a high blade and leaving the cuttings in place.

To help the Pavo Real, you can plant Ruellia brevifolia and Ruellia tuberosa. Antother plant that is mentioned is Blechum, or Green Shrimp Plant.  It seems to be also one of the Ruellias.  It's hard to find in nurseries, and seems to be a garden weed.  The preferred nectar of the adults is Verbena.

Other butterflies that use Ruellia as their host plant in Uruguay are Mbatara' (dark brown with white spots), and Princesa Roja (dark brown with red center and white spots). Princesa Roja is found in Maldonado. I'm not sure if it can be seen in Montevideo. 


Painted Lady, Vanessa braziliensis

The local name for the Painted Lady is Vanesa. Its larval host plants are Marcela, Achyrocline saturoides and Malva Real, Malva parviflora. 
The adult butterfly visits Lantana for nectar.







Bataraza, Ortilia ithra

The host plant of this brown spotted butterfly is Ruellia, possibly R. coerulea and R. simplex.
The nectar plant preferred by the adult butterflies is Dicliptera tweediana, or Canario Rojo, which should be available in nurseries, but I haven't found it yet. Many photos on the internet show Bataraza nectaring on Lantana.




Diablito, Pyrrhopyge charybdis
Guayabo and other Myrtaceae
Laurel, Ocotea acutifolia

Polydamas, Battus polydamas
Aristolochia triangularis "Isipo Milhombres"

Mariposa de Peñarol, Heraclides Thoas and Mancha Rubi, Heraclides anchisiades
Both of these large black butterflies, each with their yellow stripe or red spot feed on Rue, Tembetari and the citrus trees lemon, orange and mandarin.

Panambi Moroti or Bandera Argentina, Morpho epistrophus
I mention this butterfly because, even though I've never seen it in Montevideo, it's just so big and gorgeous, a light blue floating dream. I saw some by a river in Minas, Uruguay. While the adult butterflies feed on the juices of rotting fruit, the caterpillars feed on three Uruguayan trees.

Coronilla, Scutia buxifolia, is a common small scrub tree in Uruguay. It is known as the best wood for parrilla barbeque because it makes the best embers that stay hot and don't disintegrate.  People cut this tree down wherever they find it because everybody does parrilla asados all the time. I'm told though, that if you plant it, you will have this butterfly.

Other trees used by this butterfly are Inga uruguensis and Lapachillo, Lonchocarpus nitidus.


And Many More...

These are not by any means all of the butterflies that can be seen in Montevideo and surrounding areas. There are those bright yellow ones, those white ones, some swallowtails that probably eat Rue, the tiny blues in the grass that rub their wings, the dirty yellow ones with the little brown spots, the skippers and of course all of the moths. Over the course of the next year, if I identify other butterflies in my garden, and if I'm able to find out what plants they need, I will add them to this article. 

Native Plant Garden Design

Trees

Design of the Garden

After I get more familiar with the shapes and sizes of these plants listed above, and as I learn which ones are available in plant nurseries, I'm going to design a low butterfly hedge, located all along the window of my living room.  I'll add the design to this document when I finish it.

In the meantime, I'm going to plant as many of these plants around the garden as I can, as I find them in nurseries and at my teacher's house (she shares!).  

As my teacher always says, "A plantar!". 


Native Plant Nurseries in Uruguay

Pinar Sur, Canelones
Although this nursery claims to only supply food plants, I found some nice butterfly host and nectar plants such as Mburucuya, Malva, Plumerillo, Lapachillo, and Cedron del Monte. I was not able to find the elusive Asclepias. 

Vivero El Ceibo
Carrasco, Montevideo
This lovely suburban garden center has many exotic ornamentals but also you can find some native Uruguayan butterfly hosts and nectar plants in amongst the exotics. While I was there I saw Espejitos and Erato butterflies. Available plants form this list were Verbena, Lantana, Duranta, Ruta, Ruellia, Eugenia and Plumerillo. There were several native trees, such as Anacahuita, Lapachillo, Ceibo, and Palo Borracho.

Vivero Parati
Toledo Chico, Montevideo
Many native trees, shrubs and herbaceous plants are available at this nursery. They will deliver your order after you choose your plants. The native plants I saw were Espinillo, Tembetari, Pata de Vaca, Pitanga, Ibiriapita (Arbol de Artigas), Timbo, Cina Cina, Tala, Anacahuita, Taruman, Tacoma, Ceibo, Araza, Plumerillo Rosado, Duranta, Lantana, Canelon, Verbean bonariensis, Eupatorium macrocepahlum, Rama Negra, Buddleia Amarilla, and several Ruellias. See the catalog on their website for pictures of the available native plants.

Vivero Lavender
Carrasco, Montevideo
Vivero Lavender and Tea Room is a lovely oasis just off the main street of Carrasco, Avenida Arocena, at the corner of Divina Comedia and Mones Roses. The staff is very helpful and the selection of plants is beautiful. The native plants I was able to find from my list were Verbena, Lantana, Duranta, Ruta, Ruellia and Plumerillo. The tree selection included Anacahuita, Ceibo and Palo Borracho.

The Virginia Native Wildlife Garden I Left Behind

Kitchen herbs in the foreground are mostly European, but the asters and River Birch are natives

When I moved away from Virginia 5 years ago, I was leaving 4 years worth of garden work, which included study, research and hard labor. I had spent countless hours studying butterfly lists, butterfly needs, plant lists, plant qualities and requirements. Many of the resources I used are listed here on the right sidebar::==>

Things were just starting to fill in and fulfill their ecosystem functions when we found out we were being transferred to Italy.  Even though I was thrilled to go to Rome, I was heartbroken to leave my garden behind, because I knew nobody would take care of it and understand it the way I did.

I worked with my gardener, Martin, to the point where he understood how I wanted it cared for while I was away, but he left soon after that as well.  Today I just found my notes that I left with him, on how to care for the garden, and what the names of the native plants were.  I found some photos as well. It really was hard to look at them.  My heart started pounding and my breathing got kind of fast and shallow.  It was as if I were looking at old pictures of my child, or my favorite pets!

Here, for the sake of record keeping, for when I return to Virgina and restore my garden, is the document I left for Martin on the care and upkeep of my Virginia Native Plant pollinator garden.  Some more photos are below as well.

Cory’s Garden Notes 

v  Leave as many fall leaves in place as possible – they contain the eggs, pupae and hibernating adult insects. Leaves also act as mulch.

v  Let the clover stay in the grass for the bees and butterflies.  I don’t mind the dandelions and plantains, but the tenant might.  Keep them comfortable with their surroundings. Leave the violets. Leave the Virginia Creeper unless it starts to take over. So far it’s been well-behaved.

v  Pull up the ivy, bush honeysuckle seedlings, forsythia, grape, porcelainberry, bishop’s weed, garlic mustard. Throw them out in the trash or put them in a pile on the street and call for a county unbundled brush pick-up.  Remove the vinca only if you have some other ground cover to replace it with.

v  Let seed heads persist through winter for visual interest and food for birds and chipmunks.

v  Don’t let the vinca take over the plants in the side yard, but only pull it up if you have something good to replace it with.

v  Divide the green-headed coneflower in front of the porch. Put half back in place, but about a foot forward toward the sidewalk. Place the other half on the other side of the brick steps for symmetry.

v  Tame and contain the asters and give the columbine, Japanese anemone and strawberries plenty of room to live.

v  Don’t let the white strawberries take over the gray dogwood, or the blueberries or the wood ferns. Make sure it doesn’t invade the little bed with the sensitive fern and the wood poppies.

v  I tolerate a lot of insect damage because I try to plant what insects want to eat (so that birds will want to eat the insects…)

v  The native Prunus shrubs and trees are among the most important host plants for lepidopterae, second only to the oaks. Prune the wild cherry so it’s not in the way, but let it live.

v  Hummingbirds love the zinnias. Plant some in the spring near the bird bath and the cardinal flowers.


v  Add more of the plants that survived the drought/heatwave; expand and add mass

Where to Buy Native Plants: Send me Your Tips!


Image from pixabay.com



I'm creating a clearinghouse document here of places where my readers and I have successfully purchased native plants for our native garden projects. Please send me the names, locations and a short description of the places you have bought native plants. Use the comment section. I'll add them to the text.  I'll sort by state, and by country. Thank you! Here's my list for now:

When I lived in Arlington, Virginia, I got most of my native plants from one nursery, two non-profit nurseries, and a biannual plant sale.  I also got some of my plants from neighbors who gave me cuttings, seeds or root clumps from splittings.

If you don't live in the National Capitol Area, use the resource links at the right to research other reliable providers of native plants as well as information on which plants your local butterflies and other pollinators need for food. Yes, right over there =>

USA By State

Maryland

Environmental Concern Inc.St. Michaels, MD
Environmental Concern holds native plant sales in May and in September. You can purchase from there nursery throughout the year, but check their website and make an appointment.

Virginia

The Virginia Native Plant Society keeps an updated list of native plant nurseries across Virginia.

Nature by Design
Alexandria, VA
Check their website for hours and current plant list. They will also help design and install native plant gardens.

Earth Sangha Wild Plant Nursery
Springfield, VA
Check their website to make an appointment to buy plants, view the plant list or to volunteer in the nursery.
Every year, the nursery hosts three "Open House & Plant Sale" events, one in the spring, summer, and fall.


Northern Alexandria Native Plant Sale
Formerly Parkfairfax Native Plant Sale
Alexandria, VA
This native plant sale is held twice a year, on the last Saturday in April and on the last Saturday in September. Check their Facebook page for dates, location and vendors.






Considerations when purchasing native plants

Sources of the plants: Ask the nurseries where they get their plants, or the seeds and cuttings they use to grow the plants they sell. Make sure they have an ethical source that is able to provide reliable native plant species. Also try to be sure that the native plants are not being sourced from wild foraging.

Heirloom vs Cultivar: A plant may sound like the native plant you are shopping for, but if it is a cultivar, having been bred for generations to achieve a particular color or bloom size, the plant may have lost its original qualities making it useful to the butterflies and other pollinators that depend on it. Try to find original or heirloom versions of the native plants.

Local or regional: Make sure your native plant choices are native to your area. While you may have learned that Monarch butterflies need milkweed, the different species of milkweed across the country, and even across coninents, have different chemical makeups, and might not be the proper plant to nourish the Monarchs passing through your area.

Native Plants and Butterflies in the News

Bumblebee on Coneflower. Photo from pixabay.com

By Charlotte Adelman on Chabad.org
This article was published on May 10, 2017 on the Chabad.org website. The author is a native plant gardening expert. She stopped by the Chabad in Wilmette, IL to talk with the rabbi about protecting the environment as an act of tikkun, the Torah law that requiers Jews to repair the world, both physically and spiritually. The Chabad community embraced the idea of designing a butterfly garden on the new grounds of the Wilmette Chabad Center for Jewish Life and Learning. The organization decided to replace some of the lawn with native grasses, sedges and shrubs to provide critical habitat for butterflies and other pollinators. Read more about their project at the link above.

How to Choose the Best Plants for Pollinator Gardens
By Janeen Wright on greenhousegrower.com
This article was published on May 9, 2017 on the Greenhouse Grower website.  The article looks at native plant gardening from the supply side. In the USA, people are becoming aware of the benefits of gardening for pollinators, and the demand for native plant material is growing. Native plants aren't easy to find, though.  In the article, one nursery owner in Illinois says,


“The demand for milkweed species and other native plants has skyrocketed, and many consumers are having a hard time finding a full selection of native species in garden centers,” says Grace Koehler, Sales Manager and Green Roof Professional at Pizzo Native Plant Nursery in Leland, IL. “Market demand is rising; the supply is stagnant.”


The author admits that growers still lack understanding of the native plant needs of bees and butterflies. While the consumers want to grow pollinator gardens, the nurseries aren't sure yet which plants are the right plants. The article also discusses the difference between natives and cultivars, but the conclusion of the article is that in order to meet the demand for native plants, the nursery industry is going to have to get educated and get then get stocked.

Palo Borracho: Drunk on Montevideo's Spectacular Trees

What’s Blooming Now? Palo Borracho

Whether you're driving by or jogging by, you can't help but notice these tropical beauties in Montevideo's parks, blooming in March with a lacy pink canopy. Visible from a distance, their true wonder is revealed when you look up close. Its gorgeous flowers, unique fruits, and shady leaf structure make it a coveted tree in many regions of the world.

“Palo Borracho” and  “Silk Floss Tree” are common names of the Ceiba speciosa, a tree that is native to Peru, Paraguay, Brazil, Uruguay and Argentina. It is in the same family as the kapok and baobab. It can reach a height of over 12 meters.

This tree has many showy features. The bark of the younger trees is green, turning streaky brown and green later in life. The trunk and branches are covered with thick thorns. The base of the trunk flares out in a bulbous shape.

The Palo Borracho flowers in summer to fall, before dropping its leaves. The pink and white flowers resemble hibiscus flowers. The nectar attracts pollinators such as bees, butterflies and hummingbirds. The palmately compound leaves are made up of 5-7 leaflets all coming to a common point on the stem. The tree is bare in winter. In the spring, the fruits appear, looking like woody pears. These burst open, and black seeds covered in fluffy white cottony fibers fly out. This fiber has been used as stuffing for cushions, packaging, canoes, and added to paper pulp.  The seeds germinate easily and the tree grows quickly: nearly ten feet in just two years.
