I. delavayi is the most popular and hardiest of the Incarvillea genus. Native to rocky, mountainous regions, they do best where soils are well-drained and nights are cool. Sandy soils and part shade are ideal.
In northern zones, Incarvillea should be mulched heavily in the fall, followed by immediate removal of this mulch in early spring. These plants develop a long taproot, making them difficult to divide, but this task may be be performed in spring immediately after flowering if necessary.
