PLACEMENT & CULTIVATION
A delight of early summer, the starry flowers of cupflower cover the densely branched fine foliage in a wave of ultramarine blue. Provide a sheltered spot protected from harsh winds and rain, and grow in a container for the best show of the petite gold-centered flowers. It is also useful as garden edging and massing in summer climates where heat and humidity are not extreme. It is perennial in western coastal areas, In hotter areas, afternoon shade will keep flowers color saturated and the blooms coming. Mulch with compost to keep the soil cool while supplying nutrients. If flowering slows, shear lightly in midsummer and apply flower fertilizer for a fresh crop of blossoms until frost
