|'Gloriosa' is a choice cultivar and a favorite of long standing (cultivated since 1860). 'Gloriosa' bears extremely big flowers that bloom at a young age, and large glossy leaves. This evergreen tree has a broadly conical growth habit. Leaves are dark green, leathery, glossy, broadly ovate, to 8 in. long with rust, hairy undersides. Large fragrant flowers are cup-shaped and creamy white with 9-10 petals up to 10 in. across.
