Culture
Easily grown in medium to wet soils in part shade to full shade. Likes moist, shady areas. Soils should not be allowed to dry out and need consistent supplemental watering in hot summer weather.

Noteworthy Characteristics
Carex laxiculmis, sometimes commonly called creeping sedge, is an evergreen sedge that is native to rich wooded areas in eastern North America. In Missouri it is uncommonly found in mesic upland forests in the southern part of the State (Steyermark). It typically grows in a dense rounded clump to 12” tall with grassy blue-green leaves to 12-14” long and 1/2” wide. Non-showy, yellowish-white flowers bloom in May-June atop triangular flowering stems.
Over 1500 species of Carex grow in a variety of habitats (often moist to wet areas) throughout the world. Identification of individual species can be very difficult.
Genus name from Latin means cutter in reference to the sharp leaves and stem edges (rushes are round but sedges have edges) found on most species' plants.
‘Hobb’ is a silvery blue-leaved cultivar that is commonly sold under the trade name of BUNNY BLUE. It typically grows in a dense rounded clump to 12” tall with grassy leaves to 12-14” long and 1/2” wide. Insignificant flower spikes appear in late spring.
Problems
No serious insect or disease problems.
Uses
Group or mass as a clumping ground cover in shady areas of borders or woodland gardens. Edging plant for paths or woodland areas. Also appropriate for areas with moist soils such as low spots or on the periphery of streams or ponds.
