Petrea, commonly called Queen’s Wreath and the Sand Paper plants are beautiful members of this family. Petra volubilis is well known to gardeners in sub-tropical and tropical gardens. ‘Snow Stars’, this rare white form grows to around 3metres if not pruned. It will grow dome shaped if free standing but if allowed to climb a trellis of a small tree will scramble higher.
Petrea ‘Snow Stars’ is used in gardens and parks because when in flower the stunning pure white flower will give a great contrast in the garden colour layout. The white flowers are borne in terminal heads shooting out for up the main plant for up to 20-25 cms. from all new spring growth. If planted stand-alone it maintains a dome shape eventually growing to 3 metres X 2 metres if unpruned. On a supporting trellis ‘Snow Stars’ will cover the trellis. With judicious pruning taking out weak and crowded growth and any unwanted shoots each year in late winter so the plant is easily maintained.
Petrea ‘Snow Stars’ responds well to ordinary soil, needs full sun to partial shade, and give little or no trouble in the garden. Pruning may be needed to restrict the plant to size and shape. Mulching will improve the maintenance factor making the plant much easier to grow and flower for you in your garden. In early spring just as the plants are coming back into growth a fertilising application with a complete balanced fertiliser would be beneficial.
Native from Mexico to Central America and the West Indies, Petrea are easily grown in most soil types. They have been spread around the word by garden enthusiasts over the year so are well established in many countries.
