About
Crassula rupestris subsp. marnieriana is a perennial succulent characterized by its pairs of thick, rounded leaves that are grey-green and fused at the base. This leaf arrangement envelops the stem so completely that it is often obscured from view. In certain conditions, the leaves may exhibit a reddish hue. During spring, the plant bears small clusters of white flowers at the ends of its stems, although these blooms are uncommon in cultivated specimens.
About the genus
Crassula encompasses a variety of growth forms, including succulent annuals, perennials, and both evergreen shrubs and sub-shrubs. These plants feature thick, fleshy leaves and produce small flowers that are either star-shaped or funnel-shaped, arranged in terminal clusters.
