The Story
Plant Bio
Star Magnolia is a slow-growing, multi-stemmed deciduous shrub or small tree from Japan, celebrated for its profusion of fragrant, star-shaped flowers that emerge in very early spring before the leaves. 'Royal Star' is a renowned cultivar that produces larger, fragrant, pure white double flowers with up to 30 tepals. It also tends to bloom slightly later than the species, helping its flowers escape damage from late frosts.
