Cremnosedum ‘Little Gem’: How to Care for This Tiny Clustering Succulent

Little Gem may be little but give it some time and it can turn into an entire mound of tiny rosettes. Its a compact succulent that has tightly packed leaves arranged in small rosettes. The leaves are usually olive to green, but with plenty of light, those leaves can take on a  bronze, copper and red tone. And it keeps growing. As the stems branch, new rosettes develop and begin filling in the space around them. Over time, a single Little Gem can grow into a dense cluster of miniature rosettes.

It’s compact, colorful and SOOO cute.

What Makes It Special?

It is actually a bigeneric hybrid, meaning its parents come from two different genera.

It was created by Mr. and Mrs. Robert Grim of San Jose, California, by crossing: Cremnophila nutans × Sedum humifusum. Those are two very different-looking plants. Cremnophila nutans is the larger parent, while Sedum humifusum is a tiny, mat-forming succulent. The resulting hybrid was named ×Cremnosedum ‘Little Gem’.

That “Cremnosedum” name comes directly from its two parent genera: Cremnophila + Sedum = Cremnosedum The hybrid genus ×Cremnosedum was formally published in 1981, when Little Gem was introduced through the International Succulent Institute. So this tiny plant has a pretty interesting history behind it.

How to Care for Cremnosedum ‘Little Gem’

Light

Give Little Gem lots of bright light. This is one succulent where good light can make a noticeable difference in both its shape and color. In stronger light it tends to stay lower and more compact. Its normally green to olive-green leaves can also develop beautiful bronze, copper or reddish coloring. Outdoors, it can handle direct sun, but a plant that has been growing in a greenhouse, indoors or in shade should be acclimated gradually. Start with gentle morning sun and slowly increase its exposure. Indoors, place it near one of your brightest windows. If Little Gem begins growing loose, tall or with larger spaces between its leaves, it may need more light.

Water

It stores water in its leaves, so it doesn’t need constantly wet soil. Give it a deep watering, allowing water to reach the entire root system and drain freely from the bottom of the pot. Then let the soil to dry before watering again. Avoid giving it frequent little sips. How quickly the soil dries will depend on your pot size, soil, temperature, airflow, humidity and whether you’re growing indoors or outside.

Soil

Little Gem needs a fast-draining succulent soil. A commercial cactus or succulent mix is a good starting point but you can add perlite or pumice if your mix holds moisture for too long. Your environment should determine how gritty your mix needs to be. Growing indoors with less airflow or in a humid climate? You may need more drainage. Growing outside somewhere warm and dry? Your soil will probably dry much faster. Whatever mix you choose, use a pot with a drainage hole.

Temperature

It can tolerate cooler weather better than many succulents, but we still recommend protecting container-grown plants from freezing weather. If temperatures are approaching freezing, move it somewhere protected. During warm weather, it can grow outdoors as long as it has suitable light and its soil drains well.

Fertilizer

It doesn’t need heavy feeding. If you fertilize, use a diluted balanced or succulent fertilizer while the plant is actively growing. A light feeding during active growth is plenty for most container-grown plants. Try to avoid overfertilizing in an attempt to make it grow faster. Too much fertilizer can encourage more soft, less compact growth.

Blooming

Little Gem blooms! It gives off small, yellow, star-shaped flowers in clusters above the leaves. Flowering time can vary with climate and growing conditions. Some flower from late winter into spring, while others may flower later in the growing season. 

Is Little Gem Pet Safe?

Because it is a hybrid of Cremnophila and Sedum, we also don’t want to make assumptions based solely on information about other members of the Crassulaceae family. We recommend keeping it out of reach of pets, especially if you have a cat or dog that likes to chew on plants. Eating plant material can also cause stomach upset even when a plant isn’t known to cause serious problems.

Humidity

It doesn’t require high humidity. Normal household humidity is usually fine.

What matters more is airflow and how quickly its soil dries after watering. If you live somewhere humid or grow indoors with limited airflow, the soil may stay wet longer. Use a more gritty soil mix and adjust your watering if needed.

Propagation

It is very easy to propagate from stem cuttings. Choose a healthy stem with one or more rosettes attached and make a clean cut. Let the cut end to dry and callus before placing it into well-draining succulent soil. Keep the cutting in bright light while it begins rooting. Once it has established roots you can transition it into normal care.

Troubleshooting Cremnosedum ‘Little Gem’

My Little Gem Is Green Instead of Red or Bronze

That’s completely normal. Its leaves changes color depending on its conditions. Plants grown in stronger light can develop bronze, copper or reddish colors, while plants getting less light might remain much more green.

If yours is healthy but greener than you expected, you can gradually increase its light to help encourage more colors.

My Little Gem Is Stretching

It probably needs more light. It should naturally form compact clusters. If the stems are becoming long and weak or the spaces between the leaves are getting bigger, move it somewhere brighter. Just don’t move a plant from low light directly into intense afternoon sun. Be sure to increase direct sunlight gradually.

The Lower Leaves Are Drying Up

A few older leaves drying near the base of the plant isn’t necessarily a problem. Succulents naturally reabsorb and shed older leaves as they grow. If the rest of the plant is firm and healthy, remove completely dried leaves and continue normal care.

The Leaves Are Soft or Mushy

Check the soil. Soft, translucent or mushy leaves combined with wet soil can be and indicator that the plant has been staying wet for too long. Let the soil dry and check watering habits, pot and soil mix. If the stem itself has become dark and mushy, you may be dealing with rot.

The Stems Are Getting Longer and Bending Over

As its stems grow and give more rosettes, they don’t remain perfectly upright. An established plant can spread outward and form a dense mound or mat. Look at the spacing between the leaves. If the stems are covered in healthy, compact growth then it may just be following its natural growth habit. If the growth is unusually thin and widely spaced, it may need more light.

The Leaves Are Turning Red

Little Gem is known for changing from olive green and bronze, copper and even red in stronger light. Color changes can also be influenced by environmental stresses as well. As long as the leaves are firm and healthy, stronger colors isn’t something you need to fix.

My Little Gem Isn’t Growing

Growth speed changes with light, temperature, root development and the time of year. Make sure it has plenty of light, well-draining soil and proper watering.

Tiny plant. Pretty cool story.
