Family

Aizoaceae

Botanical Name

DELOSPERMA nubigenum

Plant Common Name

Golden Ice Plant, Hardy Ice Plant

General Description

The succulent, three-sided foliage of golden iceplant forms beautiful lush green mats that remain evergreen and turn russet hues in winter. The short, fleshy leaves are a pencil's width thick and form dense low mats. For many weeks in late spring or early summer, they become covered with golden yellow daisy-like flowers that are highly attractive to bees. These open in the morning and close in the afternoon, with new blossoms emerging each day.

This native of eastern South Africa naturally inhabits rocky screes on mountainsides where conditions are both cold and dry. So, sunny locations with average to poor, sharply drained soil are ideal. Allow plants to completely dry out between water applications, and limit water through the winter months if at all possible. Cold wet conditions will cause root and stem rot. Golden iceplant is easily divided and can be propagated by seed or cuttings.

Modern gardeners love the bright hues and neat habit of this adaptable succulent. Plant it in broad shallow containers, stone troughs, rock gardens or pebbly sunny border edges. It also thrives in rock wall or walkway crevices.
