Crassula perforata is a sprawling shrublet found in the Western Cape, the Eastern Cape and KwaZulu-Natal. It grows to 60 cm in height in scrub veld in a variety of soil types.
The name perforata has originated from the fusion of the opposite leaves into each other, so that the stem may be removed, leaving the leaf pairs as one structure with a hole in the centre. This has prompted local children to make toy necklaces, using the leaf pairs as beads, or just playing with the loosened leaves on the stem. The Afrikaans colloquial name of inrygertjie (little stringer) refers to this feature. The names necklace vine and concertina crassula are also on record (Gledhill, 1981; Van Jaarsveld, et al, 2006; www.smgrowers.com).
