Purple Passion Vine: Food for the Gulf Fritillary Butterfly!

Passiflora Incarnata is one of the most exotic-looking plants I can think of, yet it is native to right here in the Southeastern United States!

Dark green foliage begins scrambling over the ground and up neighboring shrubs in May each year. Soon after, large buds open into very unusual purple flowers that attract pollinators of every sort.

Purple Passionvine is an easy to grow deciduous vine that can be found growing along roadsides and in open fields in Eastern Alabama. Large serrated leaves have 3-5 lobes and can be up to 5 inches across. This plant forms tendrils which help it climb up nearby support.

Passionvine, or Passionflower, is also often called Maypop, because of the large egg-shaped fruits that develop all along the vine. My parents say childeren used them as weapons in their day! Some say the fruit tastes much like guava, but it reminds me of green plums. The fruit will open with a 'pop' to reveal hundreds of pulpy seeds. Try sucking on them to enjoy the sourness.

Passiflora incarnata is an important larval food source for the Gulf Fritillary Butterfly, so you might observe orange caterpillars devouring your plant!

One suggestion is to plant Passionvine where it can scramble up a shrub, thus disguising the chewed leaves as you enjoy the flowers. (The caterpillars eat only the leaves & fruit--not the flowers.)

Attracting Butterflies into the Garden

Butterflies are probably everyone’s favorite garden creature. They’re beautiful, mysterious, and romantic. It’s a goal of many gardeners to attract these lovely butterflies into the garden.

Butterflies need 3 things: Water, a nectar source, and host plants on which to lay their eggs.

The preferred source of water for butterflies is a mud puddle. This can be easily created by filling a large clay saucer with clean sand. Place this in a sunny spot in your butterfly garden and keep it moist at all times.

Nectar plants are the food source for adult butterflies. You’ll need Butterfly Bush (Buddleia) of course, which is now available in many colors. Lantana can’t be beat for attracting butterflies. Clethra is a large-growing native shrub that produces sweetly scented flower spikes up to 6 inches long in either pink or white and attracts butterflies by the hundreds. These blooms come in August, a time when flowers are more scarce. You'll enjoy the fragrance as well, which reminds me of fresh honey. Clethra, also known as Summersweet and Sweet Pepper Bush requires moist soil and full to partial sun. Joe Pye Weed comes in many forms. Eupatorium Chocolate has interesting purplish/black foliage all summer and contrasting white blooms in September & October. Eupatorium coelestinum, Perennial Ageratum or Mistflower, displays bright periwinkle blue blooms in August and September. Helianthus is another late-blooming flower that butterflies love—it has large yellow sunflower-type blooms on tall stems. Of course all the beneficial insects, including butterflies, love Blackeyed Susan, Gaillardia (Blanketflower). In September, butterflies are attracted to Stonecrop (Sedums like Autumn Joy, Matrona, and Vera Jamison.) Dianthus flowers just about all summer, and butterflies are particularly attracted to this plant. You can fill in between bloom times of the perennials with annuals like cosmos, marigolds, and zinnias. Just try not to ever use pesticides in your butterfly garden, because then you would kill the butterflies you are trying to attract.

Host plants are those on which butterflies lay their eggs. Yes, the larva will eat the plants, but without a place for the babies to grow into the beautiful adult butterfly, you can’t have the butterflies! So plant extra parsley, dill, fennel, and milkweed, so you can have plenty to share with the butterflies. An added bonus is that these plants also attract many other beneficial insects!

Clethra: Pink or White Fragrant Bloom in Late Summer Attracts Beneficial Insects!

Clethra is one of my favorite native plants, but more importantly, it's a favorite plant of butterflies and other pollinators! Clethra alnifolia, better known as Summersweet or Sweet Pepper Bush, is another wonderful native plant that blooms in late summer. Obviously the common name 'Summersweet' comes from the very sweet-smelling blooms that appear right in the heat of the summer. The other common name 'Sweet Pepper Bush' comes from the attractive seed capsules that closely resemble Peppercorns.

The fragrant blooms which are 6-inch long spikes last for more than a month and attract many pollinators.

There's a Clethra for every garden, since this shrub is available in both large-growing and dwarf varieties. But when I say 'available' I realize that Clethra is truly difficult to find in nurseries. Why, I do not know.

My favorite is 'Ruby Spice' since I'm a fan of pink flowers, but the white-blooming 'Hummingbird' is much sought after, probably due to the beauty of the shrubs planted en mass around Hummingbird Lake at the famous Callaway Gardens in Pine Mountain, Georgia.

If your garden prefers a dwarf shrub, seek out 'Sixteen Candles'--a more compact plant that seems to have more bloom spikes than possible! The name was given to this plant by Michael Dirr because the upright bloom spikes really do resemble candles on a birthday cake. This plant is truly spectacular!

Whichever you find, you can count yourself lucky to have this plant in your garden. It requires only consistent moisture to keep it happy. (I'm sorry, I do know that consistent moisture is hard to provide in Georgia these days, but if you have a wet spot, a pond edge, a soaker hose, or even, as in our case, stopped up field lines because your wife didn't know any better than to plant a Weeping Willow in the wrong spot, this shrub is definitely worth the trouble!)

Of course, my favorite online source for native plants is Shady Gardens Nursery.
