I had large clumps of K. hirsuta in Oswego NY (USDA zone 5b, to 0 to -10F in most of the years I grew it, but with persistent snow cover of several inches to a foot or two) and it never wavered. It multiplied vigorously and bloomed well. Soils were clayey loams. Other dependable performers were K. northiae, K.caulescens, and K. uvaria from the eastern Cape. But then, several eucomis were also hardy. In some ways, that was a great climate. Now I'm checking out central Massachusetts, where this year it seems alarmingly like Oswego. March 3 and we still have more than a foot of snow on the ground. Ellen On Mon, Mar 3, 2014 at 8:22 AM, <arnold140@verizon.net> wrote: > Chris: > > I have Kniphofia northiae here for ten years.
