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.
