Flowering Fern

Incarvillea delavayi (in-kar-VIL-ee-uh del-uh-VAY-eye)

Family: Bignoniaceae Non-native Herbaceous (1-3 ft)

The hardy gloxinia is a showy herbaceous perennial native to central China. It is a member of the trumpetvine family (Bignoniaceae). The species epithet honors Père Jean Marie Delavay, a 19th-century French missionary and botanical explorer. 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. A raised bed or container works well. The crown should be 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. This plant dislikes hot, humid summers. These plants are good for rock gardens, Asian gardens, shade gardens and cottage gardens. Insects, Diseases, and Other Plant Problems: Slugs frequent this plant. Crown rot and root rot are potential disease issues. More information on Incarvillea .
