Butterfly Gardening

by Michelle Bacares

Finally, the gardening season is here! The plant department at Honest Weight will be in full swing this month, with an everchanging variety of plants. With so many choices, it’s sometimes hard to know what to select. I like to pick out plants based on their purpose, rather than just on their appearance. It fills me with a sense of wonder and amazement to think that most all of the plants around us a part of a bigger scheme that is beyond comprehension.

My gardening efforts started with growing culinary herbs, then medicinal herbs and, more recently, plants for wildlife. In this article, I’d like to talk about plants for butterflies. As you may be aware, the numbers of Monarch butterflies have taken a big drop in recent years — thought to be due to loss of habitat, pesticides and pollution. It’s amazing to think that these butterflies travel thousands of miles each year — to Mexico each winter, then back again in the spring. I’d like to think that I can make a difference for some hungry butterflies!

Attracting butterflies to your garden is a relatively easy task. Here are some basic principles:

• Plant for continuous blooms. Butterflies feed in our area from spring through fall. A succession of blooms will keep different species around the whole growing season. Removing dead flowers will keep many plants re-blooming. Annuals tend to have a longer bloom time than perennials and can help to fill the food gap during periods when blooming perennials are scarce.

• Feed the caterpillars. Butterfly gardening ideally involves planting food sources for both the butterflies and the larvae (caterpillars). Caterpillars tend to eat a less varied diet than the adults, so having the right plant available is crucial for their survival.

• Plant in sun. Butterflies tend to be more active, and therefore more likely to feed, in sunny locations.

Here are some favorite butterfly plants (common names in bold, Latin names in italics):

Perennials

(plants that come back year after year)

• Butterfly Weed (asclepias tuberosa) is a member of the milkweed family. It is a native of the Albany Pine Bush and does well in sandy, dry soils. Its orange blooms provide a burst of summer color.

• Butterfly Bush (buddleia davidii) has large spikes of gracefully drooping flowers. This plant blooms throughout the summer and is a butterfly magnet for many species. Butterfly Bush does best if pruned in late fall.

• Swamp Milkweed (asclepias incarnata) is a native to the area and a preferred food source for the Monarch butterfly caterpillar. It has clusters of pink or sometimes white flowers. It spreads less readily than Common Milkweed. It does well in moist soil but will also grow in good garden soil.

• Blazing Star (liatris species) is a prairie native with tall spikes of purple flowers. Liatris also makes a great addition to dried flower arrangements.

• Purple Coneflower (echinacea purpurea) is a native to the prairies. It has large purple flowers that bloom mid-summer. Besides being a great nectar source for butterflies, their dried seed heads serve as a fall/winter food source for finches.

• Bee Balm (Monarda species) is a tall, brightly colored member of the mint family. It is often red, sometimes pink, violet or white. I love its fragrant leaves. Bee Balm may also attract hummingbirds. The leaves can be prone to mildew; good air circulation and avoiding overwatering can help to prevent this problem.

New England Aster (aster Novae Angliae) is a wonderful fall-blooming perennial with small, purple daisy-like flowers. Fall is an especially important time to provide butterflies with food, as they migrate south. Goldenrod (solidago species) and Sedum Autumn Joy are also good fall-blooming perennials.

• Joe Pye Weed and Boneset (eupatorium species) are tall perennials that tend to like damp soil. They are native to the area. Their pink or white flowers can often be seen in moist areas near the side of the road.

Annuals

(plants that die at the end of the season)

• Brazilian Verbena (verbena bonariensis) is a self-sowing annual that blooms in late summer to fall. I like Brazilian Verbena for its tall, slender, wild-looking growth habit — which is somewhat unusual for annual. It would do well as part of a naturalistic planting.

• Cosmos is a tall, bright, happy-looking flower that tolerates poor soil. It comes in a wide variety of colors (white, orange, pink, magenta) and is good as a cut flower.

• Flowering Tobacco (nicotiana alata) is an interesting plant. It’s a little sticky, a little smelly, but I love its cute lemonyellow flowers. It also comes in red or white. It does well in dry soil — be careful not to overwater.

• Zinnias (zinnia elegans) are a lateblooming annual that provide color to the garden and nectar for the butterflies at a time when many other plants may be done blooming.

Other good butterfly plants include:

• Perennials: Lavender, Wild Geranium, Goat’s Beard, Ironweed, Jerusalem Artichoke, Sunflowers (also good for birds), Phlox and Yarrow.

• Annuals: Marigold, Petunias, Lantana (including lantana camara, lantana montevidensis, and lantana hybrids) and Heliotrope.
