Botanical Name: Titanopsis calcarea
Common Names: Concrete Leaf, Jewel Plant, Limestone Living Stone
📌 Product Description
Titanopsis calcarea is a compact, highly distinctive succulent known for its rough, warty leaf surfaces that resemble small pieces of limestone. The thick, triangular leaves form a tight ground-hugging rosette with textured tops in shades of grey, green, and sandy brown.
This remarkable camouflage adaptation allows it to blend into rocky environments in its natural habitat. In autumn to early winter, it produces bright yellow daisy-like flowers that contrast beautifully with its stone-like foliage.
A unique collector’s succulent perfectly suited to South African rock gardens and specialist succulent displays.
