The genus 'colquhounia' comprises flowering, perennial plants, often demanding medium to high sunlight exposure. They thrive in well-draining, fertile soil without excess moisture, and prefer temperatures between 20 and 30 degrees Celsius. Common challenges involve pests like slugs and aphids, while fungal diseases can also pose a problem if the plants are overwatered. Seasonal considerations for 'colquhounia' include reduced watering and protection from frost in winter, while during summer, the plant may require increased watering and possibly shading during peak heat hours.
