Family: Stonecrop [Crassulaceae]










Many Stonecrops have 5 petals, such as Biting Stonecrop, English Stonecrop, White Stonecrop, Pink Stonecrop, Orpine, Ice-Plant, and Navelwort (which has bell-shaped flowers but with 5 triangular points. But some particular members have 3 petals (Mossy Stonecrop), others 4 petals (Roseroot and Pigmyweed), 6 petals (Reflex Stonecrop), 7 petals (Rock Stonecrop) or 12 petals (Houseleek). It could be argued that the Stonecrops exhibit flowers with the most varied number of petals, rather like chlorine or a transition metal element exhibiting the most valences.

Most Crassularaceae are bisexual, apart from Rhodiola which is dioecious (with male and female flowers on separate plants). Many species have succulent stems or succulent leaves, or both, but not all.
