Nursery contributed plant descriptions

A wonderful shrubby angel's trumpet. This form, collected by Sean in Argentina, produces a profusion, indeed a plethora of dark blue, bellflowers hanging from each branch in spring and early summer, outstanding against the pale bark and dark leaves. These deciduous shrubs reach 6-8' tall and nearly as wide if left untrimmed. For sun to part shade, flowering best with summer moisture but tolerant of drought once established. Root hardy in USDA zone 7 and evergreen in zone 9 and above. Can be coppiced to maintain compactness but the winter structure of nearly white branchlets is an additional attraction. [SBH 6129]
This beautiful rare plant is a great asset to a garden. Becoming a small tree in our area, it’s lovely to sit under & admire the true blue, bell-shaped flowers. The flowers are 2-3” long & bloom for an extended period. They look like miniature Brugmansia flowers. Native to Argentina, it is evergreen & likes sun to part sun & average water. It can be pruned hard in early spring if it gets leggy. It grows as a large multi-stemmed shrub or small tree to 10’. Good in a container. Hummingbirds love the flowers! Just so you know, the fruit is poisonous so don't eat for goodness sake.
