Notes
Ragged robin (Silene flos-cuculi) is a perennial for pollinator gardens. It is hardy to USDA zone 5, or down to -20°F (-29°C). It blooms in late spring and early to mid summer. The flowers attract bees, so it suits a garden planted for wildlife. It grows 12 to 30 inches tall and spreads 12 to 24 inches wide, so give it a little room.
Pairs well with Jacob’s ladder, Ornamental onion, and Ruby rose.
