List of Award of Garden Merit magnolias

Last updated

Below is a list of magnolia species and cultivars which currently (2016) [1] hold 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 start flowering. They are suitable for cultivation in parks or gardens in temperate regions. [2] M. stellata is suitable for smaller gardens. All are deciduous except for M. grandiflora, which is evergreen. The AGM citation includes a hardiness rating: [3] all of the plants listed here are rated H6 (hardy down to -20 °C to -15 °C) or H5 (hardy down to -15 °C to -10 °C). This is indicated in the column marked H. Nevertheless, magnolias prefer a sheltered spot, and flower buds may be damaged by late frosts. The maximum size (height and spread) is shown in metres.
