Description

Carex laxiculmis  'Bunny Blue' (also called Carex laxiculmis 'Hobb' BUNNY BLUE) is an ornamental grass (cool season grass) that preforms well in shade and wet sites. It will tolerate some standing water but not a bunch. If you want to encourage the plant to produce new growth, then in the winter, you can prune the leaves back.

Meaning Behind the Name: This plant's leaves and stem's edges can be sharp which parallels to the word Carex'smeaning cutter in Latin. BUNNY BLUE is the plant's trade name while 'Hobb' refers to the cultivar that has silver/blue leaves.

Technically there are two types--rushes and sedges. This plant can be a rush or a sedge. You can tell the difference because rushes have rounded-off stems while sedges have edges that can be sharp.

Pest, Disease, or other Plant Problems: No major insect or disease issues.
