Crassula rupestris ssp. commutata 'Tom Thumb'

The stems of this Crassula are adorable, forming little chains of bright green, triangular leaves which grow straight upwards, looking from the top like angular rosettes and from the side like miniature green skyscrapers. The succulent leaves grow so densely that they seem to be stacked one on top of the other, and its distinctive appearance really makes it stand out in any succulent collection. The compact nature of its adorable foliage also makes it perfect for smaller pots and desert terrarium or succulent arrangements - it doesn't grow too quickly and adds a little bit of height whilst not overly dominating the scene. Keep it happy with a decent amount of bright light, and letting it dry between waters, and you'll be treated to more of its gorgeous foliage. 

Scientific Name
Crassula rupestris ssp. commutata ‘Tom Thumb’ (thick-leaved, rock-loving plant, subspecies that's slightly different, cultivar: Tom Thumb)

Common Name(s)
Tom Thumb Crassula, Miniature Stacked Crassula, Rosary Vine Crassula

Origin
This species is native to Namibia as well as rocky parts of South Africa.

Light
It's important to give your Crassula plenty of bright light. It can cope with indirect light but will do best with at least a few hours of direct sun. Keeping it on a south- or west-facing window will give it a good light level and help to keep a red tint on the leaves for that extra bit of colour.

Water
Allow the soil to dry out completely between waterings. It needs a big soak when you water, and plenty of time to dry out in between as soil that stays soggy risks root rot. During winter, leave longer between waters.

Humidity
Thrives in low-humidity environments. Make sure you aren't keeping it anywhere especially damp.

Soil
Use a well-draining cactus or succulent potting mix, or one with added grit, sand or perlite. Ensure the pot has drainage holes to prevent waterlogging. Repot every 2-3 years in spring as the plant grows.

Food
Feed every two months in the growing season, reduce to every three in autumn and winter.

Temperature
Ideal temperature is 15-26°C; make sure it does not get colder than 12°C in winter.

Pet-safe
No, this plant is toxic to pets and small humans.

Sprouts Top Tips
The red edges on the leaves become more vibrant with brighter light exposure, so keep it on a bright windowledge if you like the eyecatching colour.

Extras
The red edges on the leaves become more vibrant with brighter light exposure, making this plant a great candidate for sunny windowsills or outdoor settings in warm climates.
