Portulaca grandiflora 'Cerise' (Cerise Moss Rose) - An evergreen perennial, often used as an annual, low-growing succulent 3 to 9 inches tall by 1 to 2 feet wide with succulent narrow lanceolate 1 inch long green leaves along reddish stems and bright colored 3 inch wide cerise colored flowers that appear summer through fall. Plant in full sun in a well-drained soil and water occasionally to infrequently. Hardy to a light frost - treat it as a tender perennial in USDA Hardiness Zones 9 through 11 and an annual elsewhere. A great plant for containers, hanging baskets, as a ground cover in a rock garden or sprawling over a wall or around other larger succulents. Our plants were from a discovery of a cultivated plant growing in a Bali garden that made its way back into cultivation in the US. To distinguish it from other selections we simply called it Portulaca grandiflora 'Cerise'. Many other forms of Portulaca grandiflora have double flowers with the related Portulaca umbraticola, commonly called Purslane, usually having single flowers. Both Portulaca umbraticola and the edible garden weed, Portulaca oleracea, also commonly called Purslane, have flattened paddle shaped leaves with a rounded tip. While Portulaca grandiflora has narrow lanceolate leaves. Portulaca grandiflora is often listed as an annual that can re-seed, but in our near frost free southern California gardens this plant is definitely an evergreen perennial as it is in Brazil, Uruguay and Argentina where it is native. The name for the genus comes from the Latin name for edible purslane, Portulaca oleracea, and the specific epithet means large flowers.  The information on this page is based on our research that has been conducted on this plant in our nursery library, from online sources, and from observations made of the crops growing in the nursery, plants in the nursery's garden and those in other gardens where we have observed it. We also have incorporated comments received from others and welcome getting feedback from those who may have additional information, particularly if this information includes cultural information that would aid others in growing Portulaca grandiflora 'Cerise'.
