Notes and assumptions
- A hardy annual: sow where it is to flower in autumn or early spring, thin the seedlings, and let some plants set seed.
- A cutting-patch flower: picking the stems often keeps new ones coming.
- Flat white umbels whose outer petals are far larger than the inner ones, like a lace doily. Autumn sowing gives the strongest plants; a wild cornfield weed that has become rare.
