Kalanchoe hildebrandtii Baill.
Kalanchoe gomphophylla, Kalanchoe hirta
Kalanchoe hildebrandtii is a shrubby, succulent plant, up to 3 feet (90 cm) tall, with woody stems and lovely, smooth, silver-grey leaves. K. hildebrandtii and Kalanchoe bracteata are similar looking and sometimes mistaken for each others. They are distinguished by their flowers. K. hildebrandtii has white flowers that are not as attractive as the red ones of K. bracteata. The flowers are very small and bell-shaped.
USDA hardiness zones 10a to 11b: from 30 °F (−1.1 °C) to 50 °F (+10 °C).
How to Grow and Care
Kalanchoe care is minimal but be cautious about light levels. Strong southern light can burn the tips of the leaves. Place pots in partial sun to light shade areas when growing Kalachoes.
The flowering varieties are highly rewarding for their colorful and long-lasting flowers. They prefer bright, sunny locations, especially in the summer growing season. During the winter, consider a south-facing window. Water moderately throughout the summer and reduce watering in the winter. Let the soil surface dry out between waterings, and in the winter, the plant can almost dry out. Watch the fleshy leaves for signs of water distress. They prefer warmth. Don't let fall below 55 ºF (13 ºC). An ordinary potting soil mix is fine. Feed bi-weekly in the summer 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… – See more at: How to Grow and Care for Kalanchoe
