Stylidium graminifolium and it's hardinessGo to latest contribution by Jon Evans, 22 April 2008, 17:35. Go to bottom of this page.
I'm sorry that Stylidium graminifolium has succumbed in Northumberland. All I can say is that it is alive and well in an unheated greenhouse in Bury and has been for 5 or 6 years. Several of it's progeny are also thriving.
Good for you, Shelagh! Of course one should never judge hardiness on one individual, or indeed one place. Any idea what is the coldest tempertature it has experienced? John Richards
Here in Surrey, this Stylidium has survived the last three winters in the open garden. Of course, it is not as cold here as it is in Northumberland, but it has managed night time temperatures of -7 deg C without any problem.
