Kalanchoe tetraphylla H.Perrier
Based on an error introduced in The Plant List, the name Kalanchoe thyrsiflora has been treated by many online sources as a synonym of K. tetraphylla.
Kalanchoe tetraphylla is a very rare species closely related to Kalanchoe synsepala. It is an interesting succulent with a thick, short, upright stem that grows up to 5 feet (1.5 m) tall, bearing a terminal rosette of soft, glandular-hairy leaves. The leaves are short and broad with serrated margins. From within the leaves are produced short inflorescences with hair stalks, 1 or 2 pairs of bracts, and pale yellow-green flowers.
USDA hardiness zones 9a to 11b: from 20 °F (−6.7 °C) to 50 °F (+10 °C).
How to Grow and Care
Kalanchoe care is minimal but be cautious about light levels. Intense sunlight can burn the tips of the leaves. Place pots in partial sun to light shade areas when growing Kalanchoes.
The flowering varieties are highly rewarding for their colorful and long-lasting flowers. They prefer bright, sunny locations, especially in the growing season. Water moderately from fall to winter when the growth is most active. Reduce watering during the hottest summer months when the plants are mostly dormant and winter when the growth slows down significantly. Let the soil surface dry out between waterings. Watch the fleshy leaves for signs of water distress. An ordinary potting soil mix is fine. Feed bi-weekly during the growing season with a liquid fertilizer, or use slow-release pellets.
These small plants require repotting every few years. When repotting, take additional care in handling as the leaves are somewhat brittle and can snap easily. Clay pots work exceptionally well for planting Kalanchoes. Ensure pots can drain well, and saucers can empty easily.
