Indigenous plants of Zimbabwe Grewia occidentalis by Wayne Black Grewia occidentalis ticks many boxes in being a gem and a ‘must have’ for your bird-loving garden. In Zimbabwe, there are a variety of indigenous trees that will naturally attract fauna to the garden and one genus of shrub that fits into this category is the genus Grewia. Of the 23 species of Grewia found in this country, one specific species well worth focusing on is Grewia occidentalis var. occidentalis, commonly known as the Cross-berry or Pink Grewia. Where it occurs The plant is commonly found in the Eastern Highlands of Zimbabwe. It is a non-descript species that can be best identified when it bursts into magnificent pink flower. Don’t be put off by planting it in Harare or other parts of the country, as it is very adaptable and is perfectly content in a temperate climate. How it grows This tree grows as a scrambler or a creeper, but if pruned, can grow into a beautiful bush or shrub and can even create a thicket. It is an evergreen to semi-deciduous plant that can reach to ten metres in height if left on its own. The tree has a fast growth rate, growing up to 1.5m per year in the first 3 to 5 years. The Cross-berry can be grown in either full sun or shade and is frost and drought tolerant. It is easily grown from seed should you wish to propagate it yourself. The best place to plant it An ideal place to plant this specimen is at the base of an exotic or large indigenous tree. The Pink Grewia will scramble to the top and create a thicket in the crown and when in flower, it will put on a spectacular show. It also grows well on trellises, providing a fantastic screen if need be. If it is pruned as a bush or shrub, it can then be placed anywhere in the garden. With its non-aggressive root system, it can be positioned near buildings, paths or swimming pools. It is a nice touch to include it in a spinney of trees (many trees planted close together), which will then create a great breeding thicket for many nesting birds. 28
