Liatris does very well in my garden, including the alba variety. However, I found the alba variety to be somewhat unattractive. The white color is not very brilliant and when the blooms move down the stalk the plant looks somewhat like a weed to me. I have many of the purple variety but I removed the alba plants in favor "whiter" perennials.

Bulbs planted in Oct and Nov started growing almost immediately. Beautiful foliage has not been affected by frost, I'm waiting for blooms next season!
They have unbranched, erect stems with grass-like foliage and a bottle-brush like flower which blooms from the top down. Popular with florists. Can tolerate excess soil moisture in summer but not winter. It is a long-lived perennial bulb which increasingly multiplies in size.
