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 nice 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 of Portulaca grandiflora were from a discovery of a cultivated plants growing in a Bali garden that made its way back into cultivation in the US and were given to us by the amazing plantsman John Bleck, who grew them for several years in his Goleta, California garden before deeming them worthy enough for us to put into production. 'Double Cerise' was a vegetative sport from another selection of Portulaca grandiflora we continue to grow that has single cerise colored flowers. For more information about this plant see our listing for Portulaca grandiflora 'Cerise'. We discontinued his double flowering form as it was not as strong as the parent plant and we also grow a very nice white flowering form we call Portulaca grandiflora 'Blanca' and this one is the most durable of the Portulaca grandiflora cultivars we grow. 

The information about Portulaca grandiflora 'Double Cerise' displayed on this web page is based on our research conducted in the nursery's horticultural library and from reliable online resources. We also include observations made about it as it grows in our nursery gardens and other gardens we have visited, as well how the crops have performed in containers in our nursery field. We will also incorporate comments we receive from others and welcome hearing from anyone with additional information, particularly if they can share cultural information that would aid others in growing this plant.
