PLACEMENT & CULTIVATION
Native to Europe, this species was first cataloged in a herbarium in 1753. It is best against the dark green of shrubs, near the back of the border, and in the moon garden, where the spikes of white bells shine in the dusk. In warmer areas of its range, some afternoon shade is beneficial. Stake if needed and mulch to conserve moisture and keep the soil cool. Spreading where happy, it drops unnumerable seeds from the decorative round seedpods.
Soil pH:
Neutral to slightly alkaline
Fertilizer:
Prior to planting, mix a few inches of compost into the soil. Topdress annually.
Diseases & Pests:
Prevent slugs and snails with pelletized iron phosphate, crushed eggshells, or diatomaceous earth.
When to Cut for Bouquets:
