Action plan
- Can I plant this now?

- Start indoors, harden off, then transplant into the final bed when local timing is safe.
- How much space?
- 36 inches in-row spacing, 48 inches between rows, and 0.25 inch seed depth.
- Best companions?
- Use this as part of a diverse flowering or herb planting, and treat companion claims as site-specific rather than guaranteed pest control.
- Common failure modes?
- Needs space and a long season; cold regions may need annual culture. Deep water during bud formation; avoid waterlogged crowns. Rich, well-drained soil with steady fertility.
