Scoth Heathers are what's known as bud bloomers, with tiny plump blooms that never open, lining the stems. All the more intriguing for this characteristic, callunas also provide surprising but delightful color changes in the foliage, often having purple-hued buds on chartreuse foliage. 'Bonita' has pink to red buds on green stems in the summer, with the foliage taking on gold to orangey hues in the fall and winter. Eventually spreading up to two feet wide, but staying about a foot tall, callunas provide wonderful year-round texture and interest to hanging baskets, container planters, borders, and in mass plantings.
