How to Grow and Care
Othonnas fleshy leaves and daisy-like flowers make them excellent in a desert or rock garden (where hardy) or indoors as houseplants or greenhouse specimens.
Othonnas tend to be fairly hardy, but some of them as Othonna cacalioides, can be extremely difficult in cultivation if you do not give them the right conditions: space to develop a radicular system, better to keep them in flat pots. In summer, protect plants from direct sunlight. In the growing season, they like to be moist, fresh, and plenty of light. They don't like temperatures below 50°F (10°C).
In the warmer months, Othonnas go into their dormancy period, stop watering, place them in a shaded, cooler area, away from getting direct sunlight and with good air circulation, relatively dry. In the fall, when nights cool down, the plants may start growing on their own, but a good soaking will help them to leaf out.
A typical succulent soil mix should be suitable for growing Othonnas, but additional drainage material would be recommended. See more at How to Grow and Care for Othonna.
