This succulent will grow in a shrubby, almost tree-like style. However, gardeners can easily trim it to meet their needs in terms size and shape. While your succulent may not make the cut, trimming the root system will give it a greater chance of survival. The more you have exposure to light, the more flowers will grow during the flowering period. A grow light may be the best option for winter if your area isn't exposed to the sun for more than 4 hours per day. What hours of sunlight does a succulent need?
