Cremnosedum 'Little Gem' Care
× Cremnosedum 'Little Gem'



Little Gem' is a hybrid of Cremnophila nutans and Sedum humifusum, though the taxonomy of Cremnophila has been questioned and it is sometimes placed within the genus Sedum, thus rendering the intergeneric hybrid name unnecessary. Other cultivars have been recognized, such as 'Crocodile', which has tessellated stem markings that resemble crocodile skin. However, the Illustrated Handbook of Succulent Plants published in 2003 noted that only 'Little Gem' is the only formally named hybrid. The 'Little Gem' cultivar was made by Mrs. and Mr. Robert Grim of San Jose, California and is described as producing a low mat of small rosettes. It prefers direct sunlight and produces small yellow flowers on short stalks.

How to Care for the Plant
Water
They will need regular irrigation in spring through summer. Water when the soil is dry to the touch. Provide half the water in winter when plants are dormant.
Fertilizer
A handful of all-purpose granular fertilizer sprinkled on the soil each spring is generally all sedums require. If a sedum is growing in rich soil, it should only be fertilized every other year. Dry granular fertilizers must be watered into the soil.
Sunlight
These succulents need bright light. Place indoor plants near a southern or western window but not so close to the glass that they will sunburn. Outdoors, plant in pots around the patio or in the ground around pavers, border edges and even in rockeries. They will do very well in full or partial sun.
Soil
Provided the soil is loose and gritty, it need not be very fertile. Use a cactus soil or a mixture of half and half potting soil and horticultural sand.
Temperature
These succulents can be grown outside in the areas with the lowest winter temperatures 15°F (−9.4°C) to 35°F (+1.7°C). However, they have little frost tolerance and should be brought indoors when the temperature drops below freezing.
Container
This plant can be grown in containers. Choose a pot with enough drainage holes. Repot when the container becomes overcrowded.
