Gelsemium sempervirens

Widely grown as an ornamental vine for its showey yellow flowers. Propagated easily from cuttings taken in late spring or early summer, treated with rooting hormone, and rooted under mist.

All parts of the plant contain alkaloids related to strychnine. Although these are considered poisonous to humans and livestock, deer are apparently unaffected.

Usually found in sandy loam soils open woodlands throughout Louisiana and east Texas. In Louisiana's coastal prairies it is a gallery forest species occurring where the prairie and forest meet.

Thickets, woodlands, fence rows, and roadsides. In sandy loam soil.
