The calyx is about 8–14 mm, slightly inflated, and varying shades of purple, while the corolla is 2–5 cm (0.8–2.0 in), and with colors ranging from lavender to light pink.

[5] Chilopsis linearis is cultivated for its large, showy flowers, and tolerance of hot, dry climates.

Chilopsis is closely related to the genus Catalpa and hybrids can be made between the two genera.

The nothogeneric hybrid between Chilopsis linearis and Catalpa bignonioides has been named × Chitalpa tashkentensis.

It has been used to treat fungal infections[6] such as candidiasis and athlete's foot, as well as wounds and cough.
