Care of the shrub Rhus undulata or Kuni bush |
|
The genus Rhus, family Anacardiaceae, comprises 250 of shrubs and trees native to subtropical and temperate regions of all continents. Some species are: Rhus undulata, Rhus typhina, Rhus standleyi, Rhus integrifolia, Rhus dentata, Rhus coriaria, Rhus aromatica, Rhus glabra. Common names: Kuni bush, Karoo kunibush. This species is native to southern Africa. They are highly branched dioecious shrubs that reach 5 meters (16.4 feet) in height. They have aromatic trifoliate waxy leaves with wavy edges and bright green color. The flowers are small, cream-colored and bloom in autumn. The fruits only appear on female plants. These low-maintenance, easy-to-grow shrubs are used in bushy groups, for informal hedges, and for creating displays. Rhus undulata grows in full sun or semi-shade exposures. They resist well the Mediterranean heat and frost. These shrubs can grow in any type of soil that is well drained and not very chalky. Use a normal garden substrate with 25% coarse siliceous sand. They have high resistance to drought; water occasionally in spring and summer as long as the substrate is dry. Fertilize with compost in late winter. Prune lightly in late winter to keep it compact. They are quite resistant plants to the usual pests and diseases. They are propagated by seeds sown in spring in a seedbed. |
