Titanopsis calcarea, commonly called concrete leaf, is a low growing perennial succulent flowering plant in the stone plant family, Aizoaceae. Titanopsis calcarea is native to South Africa and grows in rocky arid areas. Its leaves are green and tongue shaped with gray bumps at the tips and are in a rosette arrangement. The plant reaches up to 3 inches in diameter. It is grown as an ornamental plant for its unique leaves and bright yellow flowers that bloom in spring or autumn. The plant thrives in well draining soil sitting in full sun to very partial shade. It is a fall and spring growing plant and should be adequately watered during that time. Watering should be heavily restricted during summer months. USDA plant hardiness zones 9a to 11b.
Titanopsis calcarea seeds require consistent moisture and humidity to germinate, but soil should not be soaking wet. Cloning boxes, ziplock bags, and other containers that retain moisture are ideal to store sown pots. Use a well draining sterilized potting mix. Seeds should be sown on top of potting mixture and lightly covered with a thin layer of sand or potting mix, just enough to cover the seeds. Germinating pots should be kept indoors out of extreme light and heat. Ideal germination temperatures range from 60°F to 80°F. Germination typically takes 2 to 4 weeks to occur. Even with optimal conditions, germination may be slow and sporadic.
