Here is a little plant that is versatile, super hardy and foolproof (as long as you grow it in sun and well drained soil). It hasn’t been in the US very long, but already has acquired the common names of “Chinese Stonecrop”, as it hails from Asia, and “Coral Reef” , (still not sure what the Coral Reef reference is). Sedum tetractinum grows only 1-2″ tall, and spreads modestly, rooting into the soil as it creeps along. It is especially dramatic spilling over edges: retaining walls, pottery, troughs, you name it.
Sedum tetractinum is also lovely enough to use in mixed succulent planters. Its rounded olive green leaves turn a lovely copper bronze shade in the autumn, and this color change contrasts well with other shades of succulent foliage. In the planter you see here it is paired with tender Sedum adophii and Euphorbia tirucalli, but it could easily accent hardy Sedum ‘Angelina‘ and Sempervivum. Pale yellow flowers appear in summer, but the blossoms are not the highlight. “Chinese Stonecrop” takes temperatures as cold as minus 30F (zones 4-9).
