Titanopsis calcarea - Concrete Leaf

This succulent has come far from its native South Africa to be awarded the RHS' Award of Garden Merit as an ornamental, and it's not hard to see why this one has caught the eye of some of the most senior botanists in the country! Its textured leaf-tips make it look more like limestone than succulent. When it flowers, the bright yellow blooms stand out against the 'stony' backdrop. And you can grow it indoors or in a greenhouse, as long as it gets plenty of bright light. Growing no taller than 4cm, this plant spreads a little further outwards than upwards, and will love a spot with some sun in your home or under glass.

Scientific Name
Titanopsis calcarea (sun-like limestone plant)

Common Name
Concrete Leaf, Sheep's Tongue, Carpet Leaf, Jewel Plant

Origin
Native to arid areas in South Africa

Light
This plant loves bright light and will thrive with a few hours of direct light each day- a south or west facing window will help it get the most of its sun in the UK!

Water
Make sure all the soil on your Concrete Leaf succulent dries out before you water it again. You can test this with a wooden skewer or similar; and be aware it will need less frequent watering in winter!

Humidity
This plant is adapted to low humidity, so most household locations will be fine. Make sure it's not somewhere too damp/soggy, and not too near an operating radiator.

Soil
Use a well-draining soil mix; one with added sand and grit, or one designed for cacti and succulents will work well here. Repot every 3-4 years in spring as the plant grows.

Food
Fertilise every two months in the growing season, reduce to every three in autumn and winter. Use a feed designed for cacti, or dilute your usual houseplant feed, for best results.

Temperature
This plant can stand a large range of temperatures as long as it stays dry. In summer, it will love temperatures from 20-32°C, and in winter can stand temperatures down to 5°C. A cooler winter will also help it grow better the following summer!

Pet-safe
Yes, but too much nibbling won't be good for pets, small humans or the plant!

Sprouts Top Tips
Allowing your Titanopsis to have a dormancy period, with less water and food, and lower temperatures, will help it to grow better when it warms up again. Use the winter as an opportunity to help your plant recharge!
