It has unusual flowers that appear in mid-spring and fall at the end of up to 8 inches (20 cm) long stalks. They are yellow to orange or purplish.

How to Grow and Care
Monanthes are easily grown, even in very small pots. They all like hot, sunny spots and well-drained soil to thrive.
The only things that can kill these plants are the cold, hot, blasting sun, and overwatering. They like to have a winter rest period where watering should be reduced to a bare minimum. The plants will begin to grow from early spring, and watering should be increased gradually until late spring when the plant should be in full growth. During the growing period, water regularly as long as the plant pot is allowed to drain and not sit in a water tray.
Monanthes may be attractive to various insects, but plants in good condition should be nearly pest-free. Repot it every 2 or 3 years to evaluate the plant's health and provide a larger growing space being careful not to damage the sensitive roots.
