Top Ten Beneficial Native Plants That Survived the 2023 Drought on Meadow Hill
By Yvonne Lelong Bordelon
Up here in Southwestern Washington Parish, about 10 miles from Folsom, we had the hottest, driest summer in years. Many “introduced” plants, shrubs and trees wilted and died. In August, the pine trees dropped their needles and went into survival mode. They usually do that in late fall. Other natives did similar things. This is how our native plants survive. They go into defense mode. Dan Gill says to wait until spring before we make any decisions about pruning or removal. Let nature take its course.
The ten plants below made it through record breaking high summer temperatures and drought and are still going strong. Plus, they increase biodiversity and feed the pollinators and other wildlife.
Agalinis fasciculata (beach false foxglove) is an annual plant that blooms lovely purple, pink and sometimes white flowers from August to October in dry or moist savannas, open w**dy areas, open flatwoods, dune hollows and tidal marshes. It is a hemiparasite which grows on the roots of certain grasses or nearby herbaceous plants. The needle-like leaves appear in clusters, hence the scientific name, “fasciculata” which means clustered.
Agalinis is a larval host plant of the common buckeye butterfly. It attracts native bees, especially leaf-cutter bees, whose females gather copious amounts of the white pollen to place in their egg chambers.
Fresh seed sprouts readily in a pot or in the ground. Store saved seed in a dry, sealed container in the refrigerator. The plants turn black when dry.
Baccharis halimifolia (Groundsel, Manglier) is dioecious (male and female flowers are on separate plants). In fall, the male pollen producing plants are more attractive to pre-hibernating native bees and honeybees than the female, nectar producing plants. Native bees use the stems for nesting.
According to Delana Tull, the leaves and flowers can be used to make a yellow dye for wool. In Creole folk medicine, groundsel was used to treat inflamed kidneys and fever. It was also used as a palliative and demulcent in consumption and for coughing. It is toxic to livestock but is eaten by white-tailed deer.
Pennington Biomedical Center in Baton Rouge conducted a study of how Baccharis extract affects metabolic syndrome risk factors such as insulin resistance and obesity.
Eupatorium serotinum (late-flowering thoroughwort) is, in my opinion, one of the most beneficial of the fall-blooming Eupatoriums. This perennial attracts honeybees and many species of solitary bees, including long and short tongued bees, bumblebees, and beneficial predatory wasps. Butterflies, skippers, flies, moths, and beetles also forage the flowers.
The stems are used as pollinator nesting sites. The leaves are browsed by deer. The seeds are eaten by wild turkeys, song sparrows, goldfinches, juncos, and other seed-eating birds. The blooms are foraged by Monarch butterflies during their fall migration.
Tull states that it can be potentially toxic, however it has been used in rural areas for years, as an herbal tea to induce a sweat to break a fever.
Helianthus spp. (Sunflowers), especially perennials H. angustifolius (swamp sunflower), and H. simulans (Muck sunflower) and the annual H. annus, are important food sources for wildlife and pollinators. Swamp sunflower and Muck sunflower are very similar in appearance. The difference between the two is that H. simulans is taller and more robust than H. angustifolius. The fall blooming H. angustifolius and H. simulans are large and showy here in Southeastern Louisiana. They attract a variety of insects including bees, wasps, flies, butterflies, and pollen-feeding soldier beetles. Native bee species that visit sunflowers include specialists in the genera Diadasia, Melissodes, Eucera, Svastra and others.
Leaf cutter bees may use the dead hollow stems of large sunflowers as nesting sites. Sunflowers are larval host plants for silver checkerspot caterpillars. Countless birds and other creatures relish the seeds. Deer browse the plants.
Ipomoea spp. (Morning glories) such as I. batas (sweet potato), I. coccinea (red star), I. cordatriloba (tievine), I. hederifolia (scarlet creeper), and introduced I. quamoclit (cypress vine) are annuals. As far as the two red ones, scarlet creeper and red star, experts still disagree as to their origin, but both are pollinator magnets. All the species listed (except sweet potatoes) reseed readily.
The numerous flowers which open each morning from summer through fall, attract butterflies, such as swallowtails and fritillaries as well as native bees. The red-flowered varieties are a favorite of hummingbirds. Sweet potato has delicious, nutritious, edible tubers. The seed of the red species are eaten by quail, seed-eating songbirds and my chickens love them.
Monarda spp. Including M. citriodora (lemon beebalm), M. fistulosa (wild bergamot), M. didyma (Bee balm), and M. punctata (spotted horsemint) survived with little or no irrigation during the drought. Wild bergamot and red bee balm experienced serious die-back but should come back from the roots. The lemon beebalm died after it set seeds, as it was supposed to do. The horsemint near the birdbath is still blooming.
Wild bergamot attracts bumblebees, hummingbirds, and butterflies. Horsemint attracts a variety of native bee species. These herbs, especially bee balm and wild bergamot make delicious teas and have been used medicinally for years by Native American healers.
Tull states that the Cherokee and other tribes used these mints to treat fevers and to help them sleep. The Shakers used wild bergamot in tea to soothe a sore throat. The oil of horsemint yields Thymol, an ingredient in cough syrup. Citronellol, which is an insect repellent and an ingredient in perfumes is extracted from the volatile oils of M. citriodora (Lemon Beebalm).
Rubrus spp. (blackberries and brambles) are one of the best plants for wildlife. The blooms are foraged by honeybees, native bees, butterflies, and other insects. The berries are eaten by humans, birds, and mammals. Even the leaves are used in tea and herbal medicine.
Native bees that use the flowers include bumble bees and mining bees. Mason bees reproduce in large numbers when large stands of blackberries are growing nearby. Small carpenter bees adore Rubrus flowers and frequently use their pithy stems as nest sites. Azure butterfly caterpillars feed on the leaves, as do Io moth caterpillars.
The fruits and young shoots provide dyes for wool. Over 35 species of songbirds as well as quail and wild turkey feast on the berries. Many mammals including fox, opossum, rabbit, raccoon, skunk, and squirrel enjoy the juicy fruit. Deer browse the stems and foliage.
Salvia spp. (Sage) including S. greggii (autumn Sage), S. coccinea (tropical sage) and introduced S. guaranitica ‘Black and Blue’ (anise sage) and S. elengans (pineapple sage) are tender perennials. Tropical sage is easy to start from seed. Salvias come in shades of white, blue, pink, purple and red. Most are good honeybee plants and attract many native bees. Hummingbirds and butterflies forage the blooms of all those mentioned. Salvias bloom from late spring until the first frost in fall.
Delena Tull recommends using the leaves of any fragrant wild sage sparingly as a seasoning in soups, stews and on meats, as you would garden sage (S. officinalis). Pineapple sage is an excellent garnish for a fruit plate.
Solidago spp. (Goldenrod) is one of the most important late season pollinator plants. There are 13 Solidago species listed on Plants of Louisiana (USGS.gov). Link is: https://warcapps.usgs.gov/PlantID/Search?Type=S
Honeybees store goldenrod nectar for winter and native bees use the pollen for late season nests. It attracts solitary wasps, fireflies, soldier beetles, specialist bees, including mining bees, polyester bees, and the long-horned bee. Many butterflies and skippers forage goldenrod, including monarchs.
Although some people have slight allergies to goldenrod, many herbalists and foragers use the flowers and leaves of sweet goldenrod to make jelly and/or brew a tasty tea. It is also used to make a yellow dye for wool. Deer browse the plant and the seeds are eaten by goldfinches, juncos, and pine siskins. The leaves are eaten by rabbits and beaver.
Symphotrichum spp. (Asters) including S. praealtum (willow leaf aster) and S. latenflorum (calico aster) are perennials which cover the meadow with white, blue, purple, and violet blooms from September to November. Willow leaf aster grows up to 6 feet tall in sun or part shade and its pollen is of special value to native bees. Calico aster can be white, pink, yellow, or purple and is around 3 feet tall. Native bees and predatory or parasitoid native wasps (those that prey on insects) forage calico aster flowers. Honeybees collect pollen for winter stores.
Wild turkeys sometimes eat the flowers and seedheads. The basal rosettes are winter forage for white tailed deer. Cottontail rabbits eat the leaves. Song sparrows eat the seeds.
