(St Catherine’s Lace) The largest member of the buckwheat family, and extremely drought-tolerant. Slowly forms a woody-based rounded shrub with downy grey leaves. The small white flowers are borne in very large, upright clusters and last for months, turning a rusty colour by the end of summer. Great for insects and requires no summer water. Will eventually grow to 1.2m H x 1.2m W. Full sun. 12cm Pot.
