Common name:Blue Mist Shrub
Botanical name:Caryopteris x clandonensis

This group of shrubs grows from 2 to 4 feet tall and up to 4 feet wide. All have a mounded form, with gray green to pale green leaves. Flowers appear in mid to late summer, and appear in a range of blue hues, depending on variety. Flowers are clusters of tiny flowers and mostly form and the tips of branches, so cutting the shrubs back hard in the late winter as new growth emerges makes for more flowers.

Common name:Quaking Aspen
Botanical name:Populus tremuloides

Though iconic to the Rocky Mountains, Aspen aren't well suited to our urban and valley landscapes. They resent the summer heat and the lack of snow, and as such are prone to a host of disease and pest issues. And if that's not enough, their tendency to sucker can create a maintenance nightmare. Consider instead Serviceberry or Manchurian Ash for a similar appearance.
