Not documented here from Texas; native to the SE USA but invasively expanding its range. The type collection was made in Florida. “Once established, a population of S. floridana grows rapidly in confined or open areas, tending to choke out other plants if in a lawn or garden. Most attempts at eradication of the species fail; any disturbing of the tubers seems to encourage new growth.” “The single most important reason for its expanding distribution must be its being moved in nursery stock, especially azaleas and camellias. Since Florida is one of the most active states in the ornamental nursery trade, it is possible that nearly all of the collections of S. floridana in the southeast could be traced, directly or indirectly, to Florida.”
