Star Magnolia (Magnolia halleana, recently, M. stellata)
All magnolias have scented flowers, but the Star Magnolia is most fragrant of all, and as a bonus the flowers are double. This is a slow growing tree with an upright and open habit. Its leaf color is medium green in the summer and yellow to bronze in the fall.
The Star Magnolia has beautiful star-shaped flowers in early spring which like the Saucer Magnolia are vulnerable to late frosts. Later flowering cultivars are being developed to escape late frost or freeze. The flowers are usually white; however the cultivar "Rubra" has purple-rose flowers that fade to pink.
