This interesting succulent comes from south-east South Africa and is a spiny succulent shrub up to 60cm. Mine is grown raised as a charming caudiciform and has the appearance of a rubinesque lady. It has now come into bloom and has tiny reddish-brown flowers up and down the succulent spines. This grows in my south windowsill and has been happy in this location for several years now. Watch out for the spines!
