I purchased mine from Hidden Springs Flower Farm in 2010 for $24.95. Had bad luck the first spring when strong winds broke off the stem before it could bloom. Then it languished in a shady spot as another bush, a magnolia, spread too much. I transplanted it into its own raised bed last fall and is now showing 5 or 6 eyes. It should bloom this year.
Edit: I just checked HSFF's website and they do not have Wind Chimes for sale this year. I recall they had a 'collection' of 5 fern leafs and hybrids but it is no longer listed for this year. They are my go to vendor for species and fern leafs/fern leaf hybrids. Check their site very early next year and place your order then. They seem to sell out before midyear. You could e-mail them now and find out if they expect to have Wind Chimes next season.
