Cistanthe grandiflora 'Jazz Time' (Rock Purslane) - A succulent plant, native to Chile, that forms mounds to 1 foot tall by 3 feet wide of fleshy obovate gray-green leaves to 4 to 6 inches long. In spring through fall, rising on delicate 2-3 foot tall stems, emerge the 2 inch wide purple flowers that each last only one day. Plant in full sun to part shade in a well-drained soil with only occasional irrigation. It is often listed as hardy to USDA Zone 8 (10-20 F) but we are not in a climate that can test this but have heard from others that it gets damaged at around 18 F and does not recover so we have raised its hardiness level to 15-20 F but note that it is sometimes planted as an annual in cooler climates. This plant has long been known as Calandrinia grandiflora but recently the name Cistanthe has been reinstated for many New World species formerly placed in the genera Calandrinia. The species is a widespread polymorphic species found in north central to central Chile. The name for the genus is presumed to have originated from the genus name Cistus and the Greek word 'anthos' meaning "flower" in reference to the flowers resembling those of the Rockrose (Cistus sp.) with the specific epithet referring to its large flowers. We first received Cistanthe grandiflora, under the name Callandrinia grandiflora from Mr. John Bleck in 1991 and offered it in our 1993 and 1994 catalogs but while nice it struggled to persist in the garden. In 2004 we received a much more robust form that Dave Bernstein at Cactus Ranch called 'Jazz Time' and we have been growing this very nice selection of the species ever since. In the nursery trade this plant is often still sold as Callandrinia grandiflora and we have also seen the name Calandrinia spectabilis applied to this same plant. In Dr. Donna Ford-Werntz and Iris Perata's treatment of the Portulaceae in The Illustrated Handbook of Succulent Plants: Dicotyledons Springer Press 2002 Calandrinia spectabilis is a name noted as having unresolved application but referred to the genus Cistanthe.  The information on this page is based on our research conducted in our nursery library, from online sources, as well as from observations made of this plant as it grows in our nursery containers, in the nursery's garden and in other gardens where we have observed it. We will also incorporate comments received from others and welcome getting feedback of any kind from those who have additional information, particularly if this information is contrary to what we have written or includes additional cultural tips that would aid others in growing  Cistanthe grandiflora 'Jazz Time'.
