Gardeners' Notes:


On Apr 19, 2011, GardenDroid from Puyallup, WA wrote:

I purchased three of these last year during a fall clearance sale at my local Portland Ave Nursery. I assumed the bloom time was long since spent and that I was effectively buying root clumps for the next year's enjoyment. Imagine my delight when, after potting them up and sticking them out by the half shade corner under the tree, they got a second wind and put out another round of beautiful pink and white plumes, in September! I'm currently watching clusters of new furry red shoots darting out in every direction; I'm confident they'll perform perfectly in my PNW conditions. They tolerate the sun and neglectful watering quite well, I should add. If you see any of this variety for sale, snap them up!
