Hardy Gloxinia (Incarvillea Delavayi Rose) - This flowering grown from flower seeds features large, bright-pink trumpet flowers, similar in effect to a Gloxinia. Dark green, fern-like, leaves accentuate the commanding flowers, with stems rising higher bearing clusters of blossoms. Gardeners that live in regions with hot, humid summers may have difficulty growing Hardy Gloxinia. The fleshy taproot must have excellent drainage, especially in regions with wet winters, so best success is usually had by growing in a rock garden or raised bed. A winter mulch is recommended in Zones 5 and 6. Incarvillea Delavayi is worth growing even as an annual. Remove faded flowers to encourage more buds. Hardy Gloxina makes an excellent cutflower.
