Pebble plants (sometimes called living stones) are native to southern Africa. They look so magical that the man who discovered them thought that he had just come across some unusual stones.
Pebble plants – description
They don’t have a stalk and their leaves form pairs growing together in a bizarre shape resembling a stone.
The leaves have got an opening at the top often dividing the plant into 2 separate parts. Pebble plants in the spring form new leaves and at the same time the old leaves die away. This usually takes place in March – May.
The plant blooms for the first time after three years. The leaves open and the flower is either white or yellow.
