This herbaceous perennial is native to temperate Europe and Asia. Multiple stems arise from a spreading crown with fern-like leaves. In its second year, the plant produces masses of creamy white flowers with a fragrant, honey-like aroma. The plant prefers rich, moisture retaining loam, plenty of water, and a part shade to full sun exposure. The seeds are slow to germinate and should be kept barely covered, cool, evenly moist, and in part shade. Pot up seedlings and work up to size before transplanting out. This usually takes six weeks in the spring greenhouse or in the summer shadehouse. Space plants two feet apart.
