Deinanthe caeruleaIt may look like an exotic hydrangea, is sometimes called the “false hydrangea” and thrives in similar circumstances, but Deinanthe caerulea is something else entirely.  There seems to be no common name (other than “false hydrangea) for this lovely addition to any shady garden. Deinanthe caerulea forms a mound of crinkled foliage that spreads slowly and grows to about a foot high.

Come summer, downward, nodding heads of deep blue grace this elegant plant. Grow it where hot sun cannot scorch it and provide rich, well-drained soil with plenty of moisture. Especially cold-tolerant, it is hardy to Zone 4.
