To 70 cms in height. Masterwort is highly regarded by floral designers for the unique umbels of starry flowers, a bit like a refined Queen-Anne Lace in effect, but not at all weedy in habit. This is a seed strain, mostly producing red-flowered forms, with a few pink or white on occasion. Excellent filler plant for a moist area in sun or part shade. Also nice in mixed containers or tubs. Flowers may be cut fresh, or dried for winter arrangements. Remove faded flowers to encourage more buds, also to prevent plants from self seeding all over. Winter dormant.
