Lychnis miqueliana (Japanese Woodland Catchfly)
This lovely native to Japan's woodlands was new to my garden last year. Although it is said to be "compact" and is in my garden, I understand that Lychnis miqueliana grows from 18 to 24 inches tall. It is best suited to the woodland garden, as it prefers full or partial shade, but it can withstand a few hours of morning sun. Japanese Woodland Catchfly will go dormant if stressed by heat and drought, so keep that in mind when choosing a planting site. The one-inch coral/red, cross-shaped flowers are quite showy, as is the burgundy-tinted foliage. Zones 5-9.
