Be the first to rate this plant
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

The flowers of vesper iris open in the late afternoon over a period of several minutes, just about the time the sound of evening vespers might have wafted over an old monastery garden. It is a valuable addition to the garden also because of its late blooming season (high summer into early fall) and for its ability to bloom from seed started the same spring. The vesper iris has typical iris-looking leaf fans and abundantly branched, willowy bloom stalks rising to 4 feet. The inch-wide flowers range in color from pure white to violet.

Parrotia persica Parrotia persica
(Persian parrotia tree, Persian ironweed)
(3 user reviews)
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

Parrotia persica has one of the most beautiful foliage displays, in addition to year-round eye appeal and ease of maintenance. Reddish-purple when unfolding in spring, the leaves are a lustrous dark green in summer, and yellow to orange or scarlet in fall. Leaves hold their color for a long period. Older branches and trunks develop an exfoliating gray, green, white, and brown color that is a welcome asset in the winter garden. It grows successfully in Zones 4 to 8, tolerates sun and partial shade, and is easy to transplant. Often, vegetatively propogated forms offer more reliable fall color.
