The &bul; Ann&bul; Japanese Magnolia tree can grow to heights of ten feet in height and an equal width of ten feet with the canopy displaying a rounded shape. The dark purple color of the Ann Magnolia tree is distinct with even darker veins that parallel the petal length. The chalice (cupped) and shaped flowers on the &bul; Ann&bul; Japanese Magnolia tree mature into a rounded flower and contain 7-9 petals that reach a blooming peak in late March in zone 8 on trees that grow about 10 feet tall. When the fragrant flowers of the 'Ann' Magnolia tree mature, they will fall to the ground and form a large round circle of petals beneath the tree. The buds of the Ann Magnolia tree begin to swell anytime the weather begins to warm up, even during an Indian Winter. The Ann Flowering Magnolia tree is very cold-hardy growing even as far North as zone 5 and blooms there in April or May, and unpredictably small flowering spurts can occur anytime of the year, depending on weather.
