Description
This is a subshrub or liana with twining, flexible, woody stems that twist around each other or around other plants. Leaves oblong-lanceolate, glabrous and dark green, covered with a dense tomentum that gives them a greyish look. Foliage evergreen or semi-evergreen. Flowers in axillary inflorescences of 2 or 3, white or bluish-white. Fruit small capsules with several black seeds.
Propagation and growing
This species is propagated by seed. Germination is helped by mechanical scarification, sowing in standard substrate. It should be grown in semi-shade, in the mid-altitude zone of the south of the island, and prefers somewhat humus-rich soils.
Garden use
This species is ornamental for its profuse flowering. Because of its climbing nature, it is used decoratively on fences and walls. No fertiliser is needed for maintenance; watering should be light in winter and spring if there is no rain, and in summer watering is not recommended.
