Flower profile

Harvest papery blooms at the stage that preserves their shape.

Strawflowers thrive in sun and summer warmth, producing stiff papery bracts around small central florets. Their bold colors and durable texture make them equally useful in the garden, fresh bouquets, and dried designs.

Cut earlier for dryingFlowers continue opening after harvest. Cut when only two or three outer rows of bracts have unfolded and before the yellow center is exposed.

Planting

Surface sow, then give branching plants full sun.

Start indoors about 6–8 weeks before the last frost or direct sow after soil warms. Press seed onto moist mix because light supports germination.

01

Press seed onto the surface

Do not bury; keep humidity even until seedlings emerge.

02

Grow under strong light

Pinch only when the selected variety and production goal favor branching.

03

Plant 10–12 inches apart

Transplant after frost into full sun and well-drained soil.

Ongoing care

Keep plants blooming strongly

Maximize sun

Full sun develops sturdy stems and saturated bract color.

Water deeply, not constantly

Allow the surface to begin drying between thorough root-zone waterings.

Keep stems open to air

Spacing and low watering reduce spotting on flowers and foliage.

Cut frequently

Regular harvest keeps productive side branches forming.

Cutting and display

Cut when two or three outer bract rows have opened.

For dried flowers, harvest early before the central disk is visible. Remove foliage, bundle only a few stems together, and hang them upside down in a dark airy room.

  1. Harvest on a dry morning.
  2. Remove leaves before drying.
