If you’re looking to dress up your landscape this summer, consider these native species, which adapt readily to home gardens and provide weeks of blooms.
Daisy fleabane (Erigeron spp.) flowers throughout the season with dozens of tiny white petals that create an airy daisy bouquet. This annual grows where it pleases and not always where you want it, but its delicate form is complimentary to most plantings. Dried plants have been used in bedding to repel fleas and other pests.
|Yellowtops (Flaveria linearis)|
Soft-hair coneflower (Rudbeckia mollis) makes a strong presence with gray-green leaves with soft hairs and a sturdy stem that supports multiple yellow flowers. It is very statuesque and makes an impact when grouped together. There are at least nine members of this coneflower family in Florida, and they grow in diverse habitats including swamps, pine flatwoods, hammocks and sandhills.
False petunia (Ruellia caroliniana) will make itself at home in just about any garden situation, where its light blue flowers create a cooling effect. Its exploding seed capsules may spread over a wide area, but it is a good filler plant and grows where other things won’t. It is single-stemmed in shade but happier in sun, where it forms a compact 12- to 15-inch plant that blooms continuously this time of year.
Poppymallow (Callirhoe papaver) is seldom found in the nursery trade, but the low-growing plant is a showstopper with 2-inch bright-pink poppy-shaped flowers. Each mature 8- to 12-inch rosette will have more than 30 blooms that you’ll enjoy for weeks. It is a plant that must be in the “right place” to be happy. While its natural habitat is an upland mixed forest, poppymallow can be grown in home landscapes in light shade.
Frogfruit (Phyla nodiflora) continues to amaze me as the busiest plant in the garden since it is always covered with small insects and butterflies that visit its tiny match-head flowers. This plant is a fast mat-like spreader and is a good candidate for naturalizing in a sparse lawn, septic mound or retention ditch. I like it best in a hanging basket or trailing out of a large display patio container. It may go dormant in drought but revives after rain. Frogfruit is a larval host plant for the white peacock butterfly.
Threadleaf Coreopsis, also called Leavenworth’s Coreopsis, (Coreopsis leavenworthii) is always a part of the summer garden, although it does not do well in prolonged drought. Try using it in light shade, and remember it will re-seed bountifully on bare ground or in nearby potted plants.
|Blanketflower (Gaillardia pulchella)|
Bluecurls (Trichostema dichotomum), a member of the mint family, is becoming a well-known annual that returns by seed in well-drained sunny gardens. It emerges after spring has passed to form a 30-inch-tall well-branched plant. Look closely to admire its spotted lower lip petal beneath a blue-lobed corolla with four amazing long-curled stamens. It’s a great drought-tolerant plant for the whole state.
Most wildflower vines take advantage of summer heat and rains to increase growth and initiate flowering. Vining leaf tendrils will rapidly cover fences and trellises, forming a cascade of leaves and flowers.
Coral honeysuckle (Lonicera sempervirens) vines produce red tubular flowers during the summer, which are frequently visited by hummingbirds. These plants can grow in shade but bloom best with at least a half day of sun.
There are several Florida Clematis species that can be seen growing over shrubs and trees in shady sites. These adapt well to gardens and delight us with intriguing upside-down bell-shaped flowers followed by seed heads with feathery attachments. They are often referred to as leather flower or leather leaf.
Many vines often sprawl along the ground in native habitats. Some, such as purple maypop or passionvine (Passiflora incarnata), can take over in the home garden so plan to prune. This plant is a larval host for the common gulf fritillary butterfly. During summer, you’ll see ominous orange caterpillars with harmless black hair-like spines.
Beautiful flowering vines that contribute to dune stability on our beaches include members of the morning-glory family, such as purple railroad-vine (Ipomoea pes-caprae) and yellow beach morning-glory (Ipomoea imperati). Both have stout stems and succulent foliage to keep them hydrated and aid in salt resistance. Look for smaller, more delicate flowering vines in the pea-family when visiting natural areas.
Shady areas can also support wildflowers as long as shade is not too deep and the soil too dry. High shade from pines and shifting shade during the day create niches for wild plants.
Elephant’s foot (Elephantopus elatus) forms a ground-hugging plant with strap-like leaves. It survives drought and even light mowing to form large patches under trees. It blooms in late summer.
|Scarlet hibiscus (Hibiscus coccinea)|
Firebush (Hamelia patens) is always a star in the shade garden, growing 4 feet high and wide and luring butterflies and hummingbirds to feed from its numerous red-orange tubular flowers. It’s a good bet for a dry site. It is best grown in areas with minimal winter frost — but who thinks about frost during the Florida summer!
