Sapphire jewelweed's serrated leaves are the color of polished jade, while the flowers are a remarkable sapphire blue. Far different from the traditional flat-disk shape of most bedding impatiens, the flower shape of this impatiens resembles an elegant crane in flight.

Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

This pretty little blue-violet iris with yellow and white falls is native to the central U.S. Its early summer flowers are somewhat hidden among the foliage, as the stems are shorter than the leaves. In the wild, it grows in damp areas. In the garden, it appreciates a moist soil, especially in hot climates. Grow it where its flowers can be seen, such as at the front of a border, in a woodland, or at waterside.
