BONNIE'S GARDEN--Now is the Time to Plan a Summer Butterfly Garden

I get so many questions these days about what flowers to plant for a “butterfly” garden.  Well, if we don’t start planting things for the caterpillars to eat, we won’t have to worry about butterfly gardens because there won’t be any butterflies.  Here is a short list of good “host” plants:

Passiflora aka Passion Flower.  Passiflora is a host plant for fritillary butterflies and Zebra Longwings.
Alcea aka Hollyhocks.  Host plants for Painted Lady Butterflies

Oaks, willows, maples, hawthorns, hickory, elms-- (yes, some of our best host plants are trees.)  According to Bringing Nature Home:  How You Can Sustain Wildlife with Native Plants (by Douglas Tallamy, Professor of Entomology and Wildlife Ecology at the University of Delaware), oaks are a host plant for 534 lepidoptera (butterfly/moths) species alone; willows 455 species; maples 285 species.

Dill, fennel, parsley, rue, Queen Anne’s Lace—These are host plants for Black Swallowtail butterfly caterpillars.  I love dill, but when I plant it, I always plant a couple of extra plants that are my “sacrifice” plants for the caterpillars and I transfer all the caterpillars to those plants.

Snapdragons are host plants for Buckeye butterfly caterpillars.

Violas, including our little wild violet, are host plants for certain Fritillaries.

Of course, Milkweed (asclepias) is the host plant for Monarch butterflies.  Asclepias incarnata and Asclepias Syriaca are both native to the northeastern U.S.

Other good host plants are Rudbeckias (Black-Eyed Susans), Goldenrod (Solidago), Coneflowers (Echinacea), Rue, Shasta Daisies, Verbena, Baptisia, Spicebush, Sweet Bay Magnolias, Dogwoods, sunflowers, Artemisias, sunflowers, phlox, asters, even azaleas and morning glories. There are many many more plants out there.  Whenever possible, plants that are native to our area are always good to plant because these are the plants that the butterflies expect to be here.

Remember that caterpillars are VERY specific about what they will eat.  If you want to protect your Black-Eyed Susans and move the caterpillars elsewhere, they will die.  Maybe next year, plant an extra Black-Eyed-Susan specifically for the caterpillars.

But there's more to it than just planting host plants.  Maybe, in the future, I should be a bit more cautious before running to the pesticide aisle and picking up a product to kill caterpillars.  Maybe I should do a bit of research first, and see if I can identify the caterpillar.  Maybe I should just wait it out.  After all, most caterpillars are out munching for such a short period of time—usually a week or two.  You can always apply a product later, if necessary, but once you apply it, you can’t un-apply it.

If you want a great butterfly garden, start with feeding the babies.
