When should I sow cornflower seeds?

Sow from March to June. Seedlings usually appear in 7–14 days. Watering: moderate; keep soil moist but not waterlogged.

Do cornflowers self-seed?

Yes, they often self-seed to return year after year.

Can cornflowers grow in pots?

Absolutely, they thrive in containers with good drainage. It is suited to beds, borders and pollinator-friendly gardens. It is an annual, completing its whole life in one season, so sow again the following year.

Do these seeds make a good gift?

Yes — this is a straightforward packet to give, and what makes it work as a gift is mostly timing. Sowing runs March to June, so a packet given inside that window can go straight in, and one given outside it keeps perfectly well until the season comes round. There are approximately 200 seeds in the packet, so there is plenty to share. On effort it looks after itself, which matters if you are giving it to someone new to growing. It suits beds, borders and pollinator-friendly gardens, so it works for a small space as well as a garden.
