How to Grow and Care
Like many South African desert plants, Concrete Leaf Living Stone tends to become dormant or semi-dormant during the height of summer to conserve moisture. It is often a mistake during mid-summer to keep the plants wet, although they require some water during this period.
Titanopsis are all fairly similar plants and seem to make most of their growth in the fall, with another shorter burst in the spring. Flowers may be produced in fall, spring, or both. This charming little plant is worthy of a place in most collections. Concrete Leaf Living Stone is quite tolerant of temperatures down to 40 °F (5 °C) if kept fairly dry. Like most plants, it will benefit from good ventilation.
Concrete Leaf Living Stone should be kept in a bright, sunny situation at all times. It will grow well in a south-facing window.
Water this succulent well during the spring, allowing the to dry between waterings. During the summer, the semi-dormant Concrete Leaf Living Stone should be watered sparingly to avoid any chance of it rotting.
