Royal Purple Smokebush is a deciduous shrub that is highly prized for its stunning foliage and unique smoky appearance. The plant gets its name from the billowy, smoke-like clusters of small, pinkish-purple flowers that appear in late spring or early summer. Known for its attractive deep purple leaves are its most striking feature. The leaves have a velvety texture and are oval-shaped with serrated edges. As the summer progresses, the foliage intensifies in color, turning even deeper shades of purple. In the fall, the leaves often transform into vibrant shades of red, orange, or yellow, adding to its overall appeal.
In terms of size, the Royal Purple Smokebush typically grows as a medium-sized shrub, reaching a height of about 8 to 15 feet (2.4 to 4.5 meters) and spreading up to 10 feet (3 meters) wide. However, its size can vary depending on the growing conditions and pruning practices. The shrub has a rounded and bushy habit, creating a visually pleasing and full appearance.
- Sunlight: It thrives in full sun to partial shade. For the best foliage coloration, provide it with at least six hours of direct sunlight per day.
- Soil: Well-draining soil is essential for the health of the plant. It can tolerate various soil types, including sandy or clay soils, but prefers slightly acidic to neutral pH levels.
- Watering: Once established, Purple Smokebush is somewhat drought-tolerant and requires moderate watering. Water deeply and regularly during prolonged dry periods, particularly in the early stages of growth.
- Pruning: Pruning can be done in early spring before new growth emerges to control the size and shape of the shrub. It can be pruned back hard if necessary, as it tends to produce vigorous regrowth.
- Fertilizer: Purple Smokebush generally doesn't require heavy feeding. However, an application of balanced slow-release fertilizer in early spring can help promote healthy growth and foliage color.
