Web Designer carries some of the largest blue flowers you will find on a spiderwort, set on a lush, tidy clump of thick, wide leaves. Unlike many spiderworts that fade out in summer heat, it stays fresh and keeps blooming well into fall.
It adapts to sun or shade and makes a strong, long-lasting accent for borders, woodland edges and rain gardens. Pair it with Webmaster for a purple-and-blue combination.
What it looks like
Large, triangular, three-petaled flowers about 2 inches wide in clear medium blue, with fuzzy blue filaments and yellow-tipped stamens at the center, opening from bud clusters at the stem tips. Leaves are thick, wide, strap-like and arching, medium green, forming a lush, dense clump. The plant is 18 to 24 inches tall and wide. At peak it looks like a full, leafy clump studded with big blue triangles.
Growing it with lavender
Spiderwort prefers richer, moister soil than lavender, so plant it in a rain garden, near a downspout or in a partly shaded border rather than in the dry lavender bed.
Care
Grow in full sun to shade in average to fertile soil with regular moisture; it tolerates damp spots. Hardy in zones 3-9; if the foliage flops or looks tired in midsummer, cut it back by half to get a fresh flush of leaves and flowers.
