|---|---|
| Direct sow / transplant outside | Apr 17–Apr 24 |
| Estimated harvest | Apr 16 '29–Apr 23 '29 (~730 days after transplanting) |
Spacing: about 2 square feet per plant (square-foot-gardening spacing). Mature height: 4-6.5 ft.
Valerian is a tall perennial grown for its root, historically one of the best-known herbal sedatives, and it takes a full two seasons in the ground before that root is ready to harvest.
