'Snow Cap' broad-leaf sedge
Carex siderosticha 'Snow Cap'

Zones: 5 to 9
Conditions: Part to full shade; average soil
Size: 6 to 8 inches tall; 12 to 15 inches wide

What is new? Imagine this as the reverse of 'Variegata' broad-leaved sedge. That cultivar has a broad green leaf with a thin white stripe. But 'Snow Cap' has a broad, creamy white leaf with a thin green stripe.

What does someone who has grown it say? Though it has very little green in its leaf, 'Snow Cap' is just as vigorous –and as deer-resistant as other broad-leaved sedges. Also like it's cousins, it can look a little ratty at the end of the season, but this isn't the plant's fault: slugs will eventually take their toll with any member of C. siderosticha.
