It is usually said to prefer sun to part shade and is considered a good native shade plant for Florida. Though it is somewhat drought-tolerant, it may need supplemental water during dry spells.
Its native range reveals that it is not very tolerant of cold. It ranges from northern South America north through the West Indies, Central America, and Mexico to Florida and the southern tip of Texas.
It blooms and produces seeds throughout the year and can expand rapidly under favorable conditions, so much that some gardeners deadhead it to keep it within bounds. Tall grasses, however, may limit its spread. Scorpion's Tails in South Texas have been observed to increase when taller grasses are cleared away.
A South Texas friend of mine found that it transplants easily. He moved one that had come up in a neighbor's rock garden into his prepared garden soil. It adjusted quickly and is now spreading seed and attracting hordes of butterflies. One of its other common names is Butterfly Heliotrope.
