In the Pacific Northwest, Scotch heather (Calluna vulgaris) is widely appreciated for delicate flowers that appear from midsummer to early autumn. Then, with the onset of frosty weather, many varieties of heather put on a second show as their foliage turns glowing shades of red, orange, or golden yellow.
Scotch heather grows well in cool, moist Northwest climates (Sunset zones 2-7 and 17), but is not suited for the dry-summer, cold-winter conditions east of the Cascades.
These varieties display especially vivid winter foliage; most bloom in August and September. Shop nurseries now for plants in 4-inch pots or 1-gallon cans.
