Coris is a group of hardy perennial plants that thrive with proper light, water, soil, and temperature conditions. They prefer bright, indirect sunlight and moist, well-draining soil. Adequate watering is crucial, but soil should not remain waterlogged. Coris are generally tolerant of a range of temperatures but should be protected from extreme cold. Common challenges include susceptibility to root rot with improper watering and potential infestations of aphids or spider mites. Seasonally, coris may require protection from frost in winter and may benefit from reduced watering in dormant periods.
