Special Attributes

'Royal Star' Magnolia has larger and more showy flowers than the species...and they're fragrant! Produced in abundance at the tip of every stem on the tree, the pure white flowers are 4 inches across with 25 to petals on each flower. It blooms about two weeks later than the species, in early spring, so the flowers are less susceptible to damage from a late frost. The tree typically grows to around 15 to 20 feet tall with a spreading, rounded canopy to about 10 to 15 feet wide. We've seen no problems with pests or diseases. 

Landscape & Garden Uses

Growing upright to 15-20 feet tall and 10-15 feet wide, the Royal Star Magnolia is ideal for use as a larger specimen shrub or small tree in landscape and sunny woodland borders or to frame corners or against a large open wall in home foundation plantings. Can also be grown in large pots, planters and containers of 18 inches or more in rim diameter. A fine addition to the cut flower or cottage garden. 

Cultural Preferences

Royal Star Magnolia is easy to grow in most any moist but well-drained acidic soil of average fertility and full sun to part shade. She prefers full sun for best flowering, however will handle some partial shade. In the South, some shade during the hottest mid-afternoon hours of summer will be appreciated. Avoid constantly soggy or wet soils. In alkaline soils, apply soil sulfur and/or chelated iron to increase acidity. Pruning usually isn't necessary, however stray or damaged branches can be pruned immediately after flowering in spring. Feed after flowering in spring with a mild organic plant food or a well-balanced shrub and tree food containing iron or sulfur.
