Under a grow light, 6-10 inches away works well) with some direct sun (right in the window where sun actually hits the leaves. A strong grow light 4-6 inches away can substitute). Best growth comes from several hours of filtered sunlight daily. Full midday sun can scorch it; too little light causes leggy, loose stems. A south or east-facing window works well.Light

Toy Cypress

Crassula muscosa

Easy

Crassula muscosa is a bushy succulent with slender, branching stems covered so densely in tiny scale-like leaves that each stem forms a perfect four-sided column - like a miniature cypress tree, which explains the common name. It grows 15-20 cm tall and, if left to its own devices, will sprawl and trail as the stems get heavier, making it equally good in a pot or hanging basket.
