Botanical Name

AMSONIA 'Blue Ice'

Plant Common Name

Blue Ice Bluestar, Bluestar

General Description

This is one of the best bluestars for the garden. Discovered at White Flower Farm in Connecticut, 'Blue Ice' is a dwarf hybrid that is believed to be a cross between among Amsonia tabernaemontana and Amsonia montana. It is a heavy-flowering, vigorous selection that looks good even after it has stopped blooming.

In spring this bushy perennial puts forth stems lined with linear green leaves that become covered with loose clusters of blue starry flowers. These are highly attractive to bees. Once the flowers are spent the clean foliage continues to look fresh until it changes to pale yellow-green in fall.

Plant bluestar in full sun to partial shade and provide it with fertile garden soil. It is ideal for woodland gardens, foundation plantings and mixed borders.
