Melianthus Major

Honey Bush. Almost hardy in very mild gardens if planted in a warm sunny border and given a protective mulch in winter. Full sun, sheltered aspect. Unfussy about soil but a rich moist soil will see the most growth. Flowers are borne on previous years growth so worth protecting through the winter. Height 2m  Is really a shrub but listed here as perennial as it can be cut back to the ground in severe winters
