Red valerian (Centranthus ruber)
USDA Hardiness Zones: 5 to 8
Size: Up to 2 feet tall and wide
Conditions: Full sun; well-drained soil
I never see red valerian in anyone’s garden, and I always wonder why. This plant is as old-fashioned as it gets, but it never gets old with me. After it flowers in late spring, I cut it back by half and it blooms again practically immediately. The constant cutting keeps it from flopping or reseeding and also keeps you in Pepto-Bismol–pink blooms from June until winter. I like to use it as a cutting plant, and I love pairing it with blue grasses, like ‘Elijah Blue’ fescue (Festuca glauca ‘Elijah Blue’, Zones 4–8).
