Oxalis pes~caprae

Oxalis pes~caprae Bermuda buttercup


This glorious plant has become an invasive weed in many countries, as can be seen on the bank above. It contains Oxalic acid, which in small doses was used to treat tapeworm and other worm infestations. In large quantities it can be extremely toxic and fatal, as it is quoted that many sheep died from gorging on this plant in Australia. It grows from small bulbs which multiply each year, like many Oxalis.

It is a native of South Africa and flowers from December to May, and can grow to a height of 30cms. The petals can be used as a yellow dye.
