Melianthus major


USDA Zone: 9-10

Plant number: 1.359.100

A spectacular specimen foliage plant, particularly effective in containers or in a prime frontal position in the border. This forms a large clump of blue-green leaves, looking almost like some kind of exotic fern. Well worth growing as an annual in colder climates. Where hardy, this can form a large woody bush with big spikes of reddish-brown fragrant flowers in early summer. Sometimes called Peanut Butter Plant, because of the scent of the leaves when rubbed.In Zones 9 and higher this will often survive the winter. Protect from hard frost with a mulch of dry straw or similar organic material. To control the size, cut stems back in winter, leaving only two to three buds at the base. Where hardy this can grow up to 8 feet tall by 6 feet wide. In colder regions, either treat as an annual or grow in containers to winter indoors in a cool but frost-free place. Evergreen in Zones 9 and 10.
