Planting and Care Guide

Planting Tips

Plant in average to lean, well-drained soil. Space 3–4 feet apart. Water thoroughly after planting.

Care Tips

Water regularly after planting; once established it is quite drought tolerant. Cut the entire plant back hard to within 4–6 inches of the ground in early spring before new growth begins- this annual hard pruning is essential for maintaining a compact form and promoting vigorous new growth for flowering. Fertilize lightly in spring after cutting back. Largely pest-free. The bright yellow flowers in midsummer and attractive blue-green foliage are reliable season-long ornamental features.
