The flowers of incarvilleas are large for the size of the plant, and brightly coloured. They are widely flared trumpets, a few to each short stem, in the wild appearing in the summer rain after a dry spring. A few species are shrubby, with more flowers to each stem, but smaller.

Incarvillea delavayi 'Snowtop' is similar in habit to 'Bee's Pink' but has yellow-throated white flowers.
