Incarvillea (Hardy Gloxinia) delavayi
Item GG100

Incarvillea is a beautiful plant with low growing clumps of glossy, deeply divided leaves. A tender perennial with large, exotic trumpet-shaped flowers that are deep pink with yellow tubes. The plant produces bunches of 8-10 blossoms per stem. This showy, early summer perennial bares clusters of 6-10 blossoms on 12"-15" stems and has an attractive rosette of lobed foliage. Each floret is a flared trumpet with ruffles at the edges and has some resemblance to a foxglove. Excellent container plant and garden perennial that prefers full sun and fertile soil. Thrives best in a sunny location protected from winter winds. Keep faded blossoms removed to extend the bloom season of this showy perennial. Incarvillea is great in borders and rock gardens.

Notes: Hardy gloxinia is a clump-forming perennial which typically grows 18-24" tall. Features clusters of trumpet-shaped, 2.5" long flowers with yellow throats. Clusters appear in summer atop sturdy, essentially leafless flower stalks which extend well above the basal, arching, fern-like, pinnately compound, medium green leaves (to 12" long). Plant them with other summer bloomers such as Lilies, Veronica, Penstemon, and Campanula.

Planting instructions: May be planted in any well-drained soil. Dig a hole large enough to encompass the roots without bending or circling. Set the plant in place so the crown (part of the plant where the root meets the stem) is about 1-2 inches below the soil surface. Cover with soil to the original soil surface and water thoroughly. Easily grown in average, medium wet, well-drained soil in full sun to part shade. Prefers deep, moist, sandy soils in full sun. Intolerant of the hot and humid summers of the deep South and needs some afternoon shade in southern locations. Remove faded flowers to prolong bloom period. May not be reliably winter hardy in the northern parts of USDA Zone 5. Mulch crowns with straw in cold winter locations. Carrot-like tap root makes division difficult.
