Gardeners' Notes:

Positive coriaceous On Oct 15, 2014, coriaceous from ROSLINDALE, MA wrote:

This sedge is truly evergreen here in Boston Z6a, and looks great all winter.

This cultivar frequently reverts to the non-variegated form, and needs division to keep the non-variegated part from outcompeting the variegated part.

I just read the comments of a gardener on the missouri botanical garden website post that this plant almost killed her cat. After chewing the leaves, the cat could not expel them due to small barbs and required extensive medical attention. Those with pets who chew grasses may want to reconsider using this beauty.

A real winner--very graceful form and lovely color. Looked great all season spilling out of a shady half barrel.

Grew this plant in a pot over the summer and loved it! What a beautiful "waterfall" effect pouring out of the pot! I don't think it would be hardy here in zone 4a, so I brought it into the garage for the winter - hope it survives!

Friends always comment on this plant it really stands out in the shade garden. This is a 5 star plant!

I have a beautiful golden clump grown over several years. It is a real eye-catcher and brightens up a dark area.

Love this sedge! It has a lovely graceful form, looks great all year, with just a bit of fading in the winter and needing light trimming in the spring to get rid of some tatters. Through the summer it just looks better one day after the next. Always nice to find something to offset my hostas in the shade beds.
