120 Seeds Dwarf Smoketree Royal Purple Tree
The Royal Purple Smoketree is an upright, highly ornamental shrub noted for a long bloom period. It produces large flower clusters in summer that shift colors—from yellow to yellowish pink, then pinkish-purple—resembling fuzzy smoke. In fall, glossy bluish-green leaves transition to orange, peach, yellow, red, and purplish tones. Best for gardeners seeking a dramatic seasonal display and resilience to diverse soil types, including clay and drought-prone areas. Growth rate is medium, about 1–2 feet per year. Recommended for zones 4–8. Seed preparation involves heat soaking and a long stratification period (60–90 days in fridge). Germination typically occurs in spring.
Who this is best for: Gardeners who want a seed-based option with strong late-summer color and tolerance to varied soils. Great for beds, borders, and mixed shrub plantings.
Limitations: Seed germination can be slower and more variable; seed treatment is required before planting.

Buying Guide
- What form fits your space? Seed packets suit patient gardeners who want to grow from scratch; live plants provide instant color and quicker impact for smaller spaces.
