Growing Notes
Full sun and sharply drained, lean, rocky soil. It is short-lived by nature and grown hard it performs better than it does in comfortable ground. Space about 12 inches apart. Excellent on a dry slope, in gravel, or in the poor soil around a new build where topsoil is thin.

Maintenance
Let it self-sow, which is how a flax planting sustains itself, since individual plants last only a few years. Do not deadhead it to tidiness or you will lose the stand. Cut back spent growth in late fall or leave it for winter interest. No fertilizer and no summer water once established.
