Description

Bearing the name of French missionary Pierre d'Incarville, Incarvillea delavayi is grown as both a perennial and an annual. 

Its leafless stems rise up to 2 feet above the graceful, showy fern like foliage.  Atop these stems sit the beautiful 3" trumpet shaped pinkish blooms with yellow throats that bloom in the late spring.  

Situate your plant in partial shade to full sun.  In warmer climates, afternoon shade should be provided.  Its taproot is quite fleshy, so good drainage is a necessity, so a raised bed or container work well. Plant so to ensure that the crown is at or just above the soil surface.  Container growing will also allow you to move your plants indoors as temperatures drop.

Deadheading will prolong your bloom period.

Colder planting locations may require some winter mulch for protection.  

 

Insects, Diseases, and Other Plant Problems:  Slugs frequent this plant.  Crown rot and root rot are potential disease issues.
