Gardeners' Notes:

Neutral saskboy On May 5, 2010, saskboy from Regina, SK (Zone 3b) wrote:

this shrub is indeed a beautiful and hardy addition to the garden, providing interest thru 3 seasons with its wonderful changing leaf colors and vibrant flowers. But beware, it will grow larger than claimed ; mine are over 2 feet tall, not 12-18 inches as claimed on the tag when i purchsed it. Its not really a "carpet" at all.

Easy, colorful plant, and a great choice for shearing.
Two warnings, however: rabbits will prune them if it's a tough winter, and these plants will self-seed. I wouldn't call it invasive, but I do have quite a few 'Magic Carpet' babies here and there. (It might be that all S. japonica self-seed.)

The contrast that this plant provides in the landscape is wonderful, especially combined with 'Wine and Roses" Weigela. I just wish the tiny pink flowers would last a little longer. They are so vibrant compared to the lime green leaves of this cultivar.
