Opuntia is a large genus of plants native to North America and South America. All have succulent stems, some of them becoming woody with age. Stems may be cylindrical or flattened pads. Tiny, succulent leaves may be present on the newest growth (see photo below.) Most species are spiny.
If you notice one of your plants becoming top-heavy Jane recommends nipping off ten to twenty centimetres of tip growth. One Australian native plant that confuses many people about its pruning time is the Native Hibiscus, Alyogyne huegelii.hen it comes to pruning Australian native plants, we sometimes think they're a bit sensitive because they don't have a long history of human intervention that many exotic plants do. But the reality is, in the wild, native plants are pruned constantly by animals and weather.
