    This plant is low-growing and compact, with tight, spiky little flower heads that look like blue powder puffs. This is a pastel blue, sometimes tending a bit toward lavender. The blooms are long-lasting, not tending to fade or be adversely affected by weather. These look great planted in tight, close succession, and they work well both as edging along the front of a flower bed and in containers.
