This short-lived herbaceous perennial is native to Europe. The plant features downy, light green foliage, with dense, white-green flowering racemes, and prefers full sun and dryish, fast-draining soils. Germination is always spotty with catnip as the seed itself is loaded with germination inhibiting compounds. For best results, scarify the seeds and sow in the spring, either in a flat in the greenhouse or directly into a prepared bed. Space plants two feet apart.
