Coprosma

(Copros'ma)

DESCRIPTION: This group consists of about ninety tender, evergreen shrubs or small trees that are mostly natives of New Zealand. They are mainly grown for their attractive foliage and pretty fruits. C. kirkii 'Variegata' is a dwarf, spreading shrub that is a suitable ground cover. It has small, narrow, pale green leaves edged with white. C. Baueri has green leaves and its variety, variegata, has green leaves with yellow margins. C. Petriei is a low-growing shrub that is fairly hardy when planted in a sunny position. These plants produce attractive, purple or scarlet berries. Coprosma have a putrid odor when bruised.

POTTING: Coprosma can be planted outside in mild climates only; otherwise, they may be planted in greenhouses having a minimum temperature of 40 º F. They should be planted in equal amounts of sandy loam and leaf mold that is lightened with sand. Repotting is done in March and they should be trimmed into shape as soon as fresh growth begins. Water should be applied liberally in the summer, but the soil should only be moistened in the winter when it becomes fairly dry.

PROPAGATION: Cuttings of firm shoots can be inserted in the greenhouse in August or September and a bell jar should be placed over them until roots have formed.

VARIETIES: C. Baueri & var. variegata; C. Cunninghamii; C. Petriei; C. kirkii 'Variegata'.
