  • Care
    Care Information
    Thrives in enriched, slightly acidic, evenly moist, well-drained soil. Water deeply, regularly during first growing season to establish extensive root system. Provide support such as trellis or arbor, or allow to ramble on ground. Prune annually to control size. Sap may irritate; protect skin when pruning. Not fit for human or animal consumption.
    Light Needs:
    <strong>Partial Sun / Partial Shade</strong>: These two terms are often used interchangeably to mean 3-6 (or 4-6) hours of sunlight each day. However, there is a difference.
<strong>Partial shade</strong> typically means the plants will appreciate a more gentle exposure such as the weaker morning or early afternoon sun, with the emphasis on providing the minimum needed shade and sheltering from intense late afternoon sun. <strong>Partial sun</strong> typically means the plants <u>need</u> some direct sun, so the emphasis is on meeting the required minimum hours of sunlight, with filtered sunlight or shade the balance of the day.
Both are best with shelter from the harshest late afternoon sun. This shade could be provided by a structure, a wall, larger plants or  tree(s).

  • History & Lore
    History:
    Both species of Gelsemium are native to the southeastern U.S., most notably the Carolinas. G. sempervirens bloom times range from late winter to early spring; G. rankinii blooms in spring and repeats in late summer to fall.
    Lore:
    The genus Gelsemium was classified by French botanist, Antoine Jussieu and named it for the similarity to Jasmine. These plants contain a potent alkaloid similar to strychnine.
