List of Award of Garden Merit magnolias

Below is a list of magnolia species and cultivars which have gained the Royal Horticultural Society's Award of Garden Merit. Magnolias are shrubs or trees which put on a showy display of tulip-like flowers, often scented, in early to late spring. Many are slow-growing and may take several years to flower. They are suitable for cultivation in parks or gardens in temperate regions.[1] M. stellata is suitable for smaller gardens. All are deciduous except for M. grandiflora, which is evergreen. All magnolias require shelter from cold winter winds. Those cultivars marked f may not be frost-hardy.
