GARDENING FOR BUTTERFLIES

IMG_0385rwtmk1.jpg

You have decided to plant a butterfly garden? Before you put spade to soil, ask yourself these basic questions and consider these steps:

    1. What are the reasons for this garden? Do I want to attract butterflies for nectaring or egg-laying?
    2. How much time and money do I have to spend on this project?
    3. Who will maintain this garden?
    4. What is my proposed site like?
    5. Which plants will thrive here?
    6. What is my focal point in this garden?
    7. Make a drawing of your proposed garden. Frame the focal point.
    8. Prepare the soil.
    9. Plant.
    10. Mulch.

    Clarify Your Reasons

    It is important to clarify your reasons for your new garden. This will determine what you plant there. If you are interested in learning more about butterflies beyond observing them feed, you might want to include plans for host plants so you can see different behaviors such as courtship, mating, egg-laying and more. If your main objective is to just provide nectaring plants for adult butterflies and also have flowers suitable for cutting and arrangements, you will plan in different way. You might want herbs for your table or color for your outdoor spaces in addition to your butterfly plants. Consider the different uses of the garden.

    Time/Money Considerations

    How much money will be needed for soil amendments, plants, mulch and borders? Who will fund this project? Who will have time to help dig and plant the garden initially? Do you want to install the garden all at one time or plant over a period of months? Will plants be donated or will you need to buy them? Could seed be used for some plants in order to save money?

    Maintenance

    The most important decision to make concerning a butterfly garden is, “Who will take care of this garden?” Without regular watering and weeding, the best butterfly plants available will fail to thrive. Is there a hose or water sprinkler nearby? How much time/week will be required for this garden during the growing season? How many people have committed to weeding and watering? If you find that the time or cost of maintaining a large garden is prohibitive, consider planting a smaller one which can be expanded later, or perhaps even attractive raised beds.

    Looking at the Site

    It is important to think about the place where you want your new garden to be. How much sunlight does it receive each day? What is the exposure? Will the garden be sheltered from winds by a building, trees or shrubbery? Shelter is very important for butterflies as it will protect them from the elements. Evergreens are good because they provide shelter on days when the weather is variable.

    Is the soil adequate or will it need some help? Are there a lot of obstacles there such as rocks, underground utility lines, water lines, etc.? Good soil means healthy plants and healthy plants are best for butterflies. Sometimes it takes years to build up a good soil, but you can still have the garden in the meantime. Ammendments such as compost can be added each year to enhance the soil.

    Locate the water source and see what hoses or sprinklers will be needed. If you use native plants, you will have fewer water considerations because the plants are more acclimated to the local conditions. Sprinklers are the least effective way to water because they can wash out the nectar from the plants.

    Plant Selection

    Please excuse the forthcoming pun, but: There are many plants to choose from, but few will make the final cut!

    Indeed, there are a variety of plants that would probably serve well in your garden, but will they WORK HARD? A plant that pulls its own weight is vital.

    I like plants that meet several criteria for my butterfly garden. I want a plant that will function as food, shelter or a host plant for the butterflies. I want a plant that will survive in the location and be healthy. I want a plant that is NOT on the invasive plant list for Tennessee. I want a plant that does not have to be fussed over. I want a plant that will provide color, fragrance or interest for the inside of my home. I want a plant that doesn’t irritate my neighbors.

    Another consideration that will become even more important in the future is water usage. Try to incorporate as many plants as possible that do not require too much water unless, of course, you have a wet area.

    A few plants will meet all of these needs, most of them are natives. A few will meet some of the needs, and may even be used because of sentimental reasons. Some will meet few, if any, needs and these should be eliminated from your plant list. The orange milkweed (Asclepias tuberosa) shown below with a Black Swallowtail, is a strong native plant that provides good nectaring for many butterfly species, is a host plant for the Monarch, does not require much care, is not invasive and should last for many years as it is a periennial. It will spread but can be contained. In the fall, the seed pods add to the dried floral arrangements.

    Here is a chart of various species of milkweed you can plant in your garden (each species has particular soil preferences, so you are sure to find one that meets your requirements):

Species Color Height Blooms Conditions
Curly Milkweed (Asclepias emplexicaulis) Rose purple 18-36 in. May-July Dry soil
Pokeweed (A. exaltata) White 36-60 in. June-July Dry soil
Prairie Milkweed (A. hirtella) White 30 in. June-Aug. Dry soil
Swamp Milkweed (A. incarnata) Pink, deep rose 24-60 in. June-Aug. Moist/wet soil
Aquatic Milkweed (A. perennis) White 36 in. July-Aug. Moist/wet soil
Purple Milkweed (A. purpurascens) Red-purple 24-36 in. June-July Dry soil
Fourleaf Milkweed (A. quadrifolia) White 12-20 in. May-June Dry soil
Common Milkweed (A. syriaca) Dusty rose 36-60 in. June-Aug. Dry, but adaptable
Orange Milkweed (A. tuberosa) Orange 24 in. June-Aug. Adaptable
White Milkweed (A. variegata) White 36 in. May-June Dry soil
Whorled Milkweed (A. verticillata) White 10-20 in. June-Aug. Dry soil
Green Milkweed (A. viridiflora) Pale green 12-30 in. July-Aug. Dry soil
Antelope-Horn Milkweed (A. viridis) Green 10-30 in. May-June Dry soil
    Determine a Focal Point

    *These suggestions follow the plan outlined by Janet Macunovich in her excellent book Designing Your Gardens and Landscapes (2001). The plan is modified to suit butterfly gardeners.

    Points To Remember:

    Do not use pesticides on the flowers in your butterfly garden. This can kill butterflies in all life stages – egg, caterpillar, chrysalis and adult.

    One of the best resources for planning a butterfly garden is found at the following location: Tennessee Central Basin Garden Guide. This guide is geared toward Middle Tennessee, but some of the plants and ideas will carry over into other locations as well.

I came across this website by chance. I am a teacher at East Side Elementary in Cannon Co, TN. I raised monarchs with my class last year and plan to do it again this year. The only problem is that I have a hard time finding enough milkweed to feed my babies!! I would like to have some information on how I could get plants/seeds to create my own milkweed garden. Any information would be great!!

Hi Amy,
Milkweed is pretty common in the spring at most nurseries in the area. Sometimes called “butterfly weed”, I’ve found it at Lowe’s, and many others. It’s a pretty hearty plant, too, so it will come back year after year.

For other varieties of milkweed, you might try an onine source, such as http://educationalscience.com/milkweed.htm.

We sometimes share seeds with one another at our group’s fall meeting. If you’d like to attend, just keep an eye on the website to see when the next meeting will be.

We’re always glad to hear about teachers who are interested in butterflies in the classroom!

Best,
Carter Harkins

Found this with Google, and am sending your link to my disabled sister in Nashville who is interested in my butterfly gardening here in Florida and might be able to do a small amount of gardening with host plants, otherwise already has a good habitat.

Wish your site included the various host plants for each butterfly as that would be helpful to newcomers to butterfly gardening. I know it was for me.

Hi Linda,
Did you download the pdf?

Hi Terry,
Yes, all the plants listed on our site do very well in West Tennessee.

I am going to put in a butterfly and hummingbird garden in my yard in Crossville, TN.
What plants should I get.
Thanks,
Dan

Hi Dan,
The plant and gardening guide found here is great!

Dan, I live in Crossville also and there are a couple of us the do a lot of butterfly work in Cumberland and surrounding counties. If you are interested or just want to get to know each other to share plants from garder to garden just email me.
