Blue Sedge
by June Hutson       #Hot Plants

This carex is easily grown in medium to wet soils. Ideal light is shade to part shade. Many members of the genus share the common name of rush or sedge. The cultivar ‘Blue Zinger’ refers to the bright blue color of the leaves, which endures winter in all but the coldest temperatures.

Green and white blooms occur in July to August but the flowers are inconspicuous. Mature height is 1 to 1½ feet with the same width.

Ideally, landscape use would require wet soil such as in a rain garden. However, average garden soils are acceptable and it also exhibits some drought tolerance once established. For best results, rid the plant of all foliage in late winter for a flush of new vigorous growth.
