OPUNTIA
Family Cactaceae
Optunia, native only to the Americas, imported to Europe during the 1500s and Australia in the 18th century, fast became an invasive weed, eventually covering over 1,500 square miles of farming land per year. The Australian government tried many ways to contain this menace, mechanical removal and chemicals all failed. The moth Cactoblastic cactorum from South America whose larvae eat the prickly pear was introduced in 1925, and was successful in combating the problem. Up dated 12/9/2018
Opuntia microdasys
Opuntia microdasys, Latin “microdasys” meaning small and shaggy, may also become invasive in the garden. This plant needs careful handling; instead it has no spines, instead yellow ‘glochids’ (mounds of prickles), finer than the human hair, that are lethal once they penetrate the skin. Opuntia microdasys, is easy to grow, needing only poor well drained soil and full sun.
ORBEA VARIEGATA
Family Apocynaceae
Orbea variegata, a native to the coastal belt of the western part of South Africa, has approximately 20 species. It is a leafless succulent, which makes an attractive ground cover and can form large matted clumps. The carrion-like smell from the beautiful flowers attracts flies for pollination. The plant requires a rich gritty medium of well-drained soil with river sand added to grow successfully. In the wild, these succulents are shaded by growing under larger plants. They root easily from stem cuttings. Up dated 12/9/2018
