On October 7th, I was invited to participate in rescuing prairie plants from the Gerhart Prairie south of Houston. The Prairie, I believe, is part of the Texas Nature Conservancy. A manufacturer has a fenced-off area on the property. They will put in a road through the prairie to service the fenced-in operations. We were rescuing the plants in the designated place on the future road. Several Master Naturalists identified plants, as did Mark Morganstern of Morningstar Nursery. Mark kindly reaches out to me when free and needy plants are available.
That Saturday, I received an amazing list of the plants I rescued.
1.) Helianthus angustifolia (aka Swamp Sunflower)
this is the tall 'sunflower' plant with the very narrow leaves that have the edges rolled under.
(I think I may have inadvertently referred to this as Maximillian Sunflower, which is not what this is)
2.) Baptisia sphaerocarpa (aka Yellow Wild Indigo or Yellow False Indigo)
this plant is a small subshrub in the Fabaceae (Pea Family); it has trifoliate leaves without subending bractlets and it has bright yellow flowers borne on erect inflorescences. Its fruits are round, hence the Latin name sphaerocarpa which literally means 'round fruit'. It will bloom in the spring.
3.) Euthamia leptocephala (aka Bushy Goldentop)
This plant is in the Asteraceae (Sunflower Family) and is closely related to the goldenrods (Solidago spp.). Euthamias have round-topped inflorescences rather that the 'open-spray'-shaped inflorescences of the goldenrods. There are two species of Euthamia in our area -- the other is Euthamnia gymnospermoides (aka Texas Goldentop) -- it have longer and much narrower leaves than does E. leptocephala.
4.) Croton lindheimeri (aka Woolly Croton or Lindheimer's Hogwort)
This plant is a member of the Euphorbiaceae (Spurge Family). It has very small unisexual flowers surrounding by a yellowish tomentose hairs; the female flowers are borne near the base of the inflorescence while the male flowers are bunched near the apex of the inflorescence. This seeds of this species are an important food source for quail and dove and the plant is a larval host for several species of butterfly.
5.) Neptunia pubescens (aka Tropical Puff)
A member of the Fabaceae (Pea Family) in the Mimosoid clade (or subfamily) which means it does not have typical pea-shaped flowers. The flowers are bunched onto a round receptacle or head, each with a small inconspicuous corolla, but the numerous long stamens are quite showy. Neptunia pubescens sprawls along the ground. It is larval host plant for the ceranus blue (Hemiargus ceranus) butterfly and its seeds are consumed by many wildlife species.
6.) Lythrum alatum var. lanceolatum (aka Winged Loosestrife)
This member of the Lythraceae (Loosestrife Family) grows to be about 3-4 ft tall and produces long racemose infloresceces with smallish lavendar (pink,purple) flowers. It is a special value to native bees and is also used by hummingbirds and butterflies.
7.) Eupatorium serotinum (aka Late-flowering Boneset)
A member of the Asteraceae (Sunflower Family) which has rayless sporting only white disc florets. It is a perennial that emerges early in the year, but does not bloom until August - November. While it's flowers are small there are many of them, so that the plant is a real show-stopper in the fall. It is of special value to native bees and its nectar attracts butterflies and many other insect species and it seeds are eaten by many bird species. The plants you dug up were fairly small (maybe due to the drought this year; the species usually grows 4-5+ feet tall.
8.) Agalinis heterophylla (aka Prairie Agalinis, Prairie Geradia, False Foxglove)
This is a member of the Boraginaceae (Borage or Broomrape Family). There are several species found locally, but the most common is Agalinis heterophylla, easily distinguished by its deeply lobed calyx. It is a larval host for the Buckeye butterfly and attracts numerous insect species, including bees and bumblebees.
9.) Ludwigia octovalvis (aka Mexican Primrose Willow)
A member of the Onograceae (Evening Primrose Family), this plant likes its feet wet, so a low spot that collects water is a great place to plant it. It is fast growing and reseeds readily. It is a nectar source for butterflies and other insects and is a larval host for the water primrose hornworm moth (now there's a mouthful!).
10.) Conoclinium coelestinum (aka Blue Mist Flower)
Another member of the Asteraceae whose flowerhead do not have ray florets, but the long stigmas of the disc florets make for a showy flowerhead nonetheless. This species is NOT an annual (as I misinformed you yesterday, sometimes things stick erroneously in your mind), but rather a perennial that dies back to the ground each year and also spreads readily by seed. It attracts many late-season butterflies. It can be a bit 'bossy' as Mary Spolyar put it, but as I have found with vigorous natives a bit of pruning/thinning doesn't hurt them in the least.
I look forward to watching them thrive in Symbiosis.
