Pickle plants are low growing succulents. In the spring they produce small, daisy like flowers of white or yellow.
Delosperma echinatum are native to South Africa. So they like bright sunny spots with lots of indirect light. A west or south facing window is your best. A cactus or succulent soil mixed with coarse sand or perlite is a good option.
As a succulent, a pickle plant doesn’t require heavy watering. It’s important to give your plant a good water, then let the soil dry out before watering again.
