Umbrellaworts, often referred to as 'Four O'Clocks', require moderate care. They thrive in sunlight or partial shade, with well-drained soil and regular watering, while being tolerant of various temperatures. They are prone to challenges such as aphids and spider mites, and fungal diseases aggravated by overwatering. During winter, in colder climates, they should be brought indoors or treated as annuals. With attention during the growing season, umbrellaworts's colorful flowers will add a delightful splash to gardens and landscapes.
