Flower profile

Match dwarf edging plants or tall cutting stems.

Bachelor’s buttons, also called cornflowers, are hardy annuals that establish best in cool weather. Dwarf forms make compact borders; tall forms supply straight stems for informal bouquets.

Do not overfeedRich soil and excess nitrogen create lush, floppy plants. Average soil and full sun give cleaner stems.

Planting

Direct sow into cool spring soil.

Sow as soon as soil can be worked, or in fall where winters are mild.

01

Sow ¼ inch deep

Cover lightly and keep the bed moist through emergence.

02

Thin by plant type

Use about 6 inches for dwarf forms and more room for tall cutting types.

03

Support tall rows

Add netting before stems stretch in windy sites.

Ongoing care

Keep stems strong and flowers productive

Maximize sun

Full sun keeps stems sturdy and flowering generous.

Water during establishment

Once rooted, water during prolonged dry periods without saturating soil.

Avoid excess fertilizer

Lean to average soil reduces lodging.

Cut and deadhead

Frequent harvest prevents seed set and extends flowering.

Season checkpoints

Follow the plant’s visible progress.
