Gardeners' Notes:

Positive coriaceous On Nov 17, 2012, coriaceous from ROSLINDALE, MA wrote:

Showy spires of white flowers to 30" in early June, a great companion to Allium christophii. It's a long-lived perennial, one I've grown it over 12 years (in Boston Z6a) without seeing it self-sow or produce offsets like some of its thuggish invasive congeners.

Cheaply and easily available in autumn from purveyors of spring bulbs. Why this is so rarely seen in gardens is a mystery to me.


This plant has been said to grow in the following regions:

Roslindale, Massachusetts
Honesdale, Pennsylvania
