Home Gardening Tinkerbelle Lilac Grow this great little lilac as a shrub or small tree! No matter how you train it, youll love the spicy-scent of its bright pink flowers (which emerge from wine-red buds, creating a two-toned effect) in late spring. And best of all, you dont need to worry about it getting too big — Tinkerbelle only grows 5 feet tall.
