Petit Henri Ragged Robin

Petit Henri is a compact ragged robin with white double flowers held in candelabra-like clusters above maroon calyces. Must Have Perennials lists the selection as ‘IFLYPH’ and reports an extended bloom from late spring into autumn. ## Garden use Its upright flower stems suit cottage and informal beds, meadow plantings, and containers. The developer profile gives a mature height and spread of about 18–24 inches and lists USDA Zones 3–8. ## Growing conditions Plant in full sun or part shade. The long season of double flowers can bring butterflies, bees, and hummingbirds to the garden. Allow room for the rounded, mounding clump and use a container with drainage if growing it above ground. ## Maintenance Remove faded stems as flowers finish and keep the soil evenly moist while the plant establishes.
