Many varieties of croton plants, such as the Croton ‘Petra’, are popular houseplants that thrive in sunny conditions in average room temperatures. Generally, croton plants are easy to grow indoors. Colorful croton plants thrive in room temperatures between 60°F and 70°F. Croton plants can drop leaves if they grow in cold drafts. Mist the foliage frequently and keep the soil moist in summer.
