Strawflower Growing Guide

Strawflower

Crop Rotation Group

Miscellaneous 

Soil

Fertile, well-drained soil.

Position

Full sun.

Frost tolerant

None. Strawflowers grow best in warm weather.

Feeding

Mix a standard application of a balanced organic fertilizer into the soil prior to planting. In midsummer, drench plants with a liquid plant food to stimulate new growth.

Companions

Dianthus and Thyme. Strawflowers close at night and in rainy weather, so they are at their best in sunny beds seen during the day. Blue ageratum or airy nigella make excellent neighbors for strawflowers.

Spacing

Single Plants: 11" (30cm) each way (minimum)
Rows: 11" (30cm) with 11" (30cm) row gap (minimum)

Sow and Plant

Sow seeds indoors in late spring and set plants out after the last frost has passed. Seedlings are sometimes available as bedding plants.
Our Garden Planner can produce a personalized calendar of when to sow, plant and harvest for your area.

Notes

Strawflowers are among the best annuals to grow and dry for use in winter arrangements. Colors include yellow, pink, orange, red and white, all with yellow-orange centers.

Harvesting

Cut blossoms as soon as they open and hang to dry in small bunches.

Troubleshooting

Choose tall varieties with long stems for drying. Persistent wet conditions can cause strawflowers to rot.
