Kalanchoe 'John Bleck' - An upright growing succulent with a central stem to 2 feet tall with succulent green leaves that have red serrated margins and interesting triangular auriculate basal lobes that rise perpendicular to the leaf surface. From the top of the stem arises a 12 to 18 inch tall branching inflorescence holding clusters of pendulous flowers with light purple calyces and orange petals. Plant in full to part sun and irrigate occasionally to very little. Hardiness is not well known but has withstood light frosts and should be hardy to between 25-30° F. Will produce plantlets at the bottom of the hastate leaf bases. We received this plant from noted aloe breeder John Bleck, who received it from Ed Mercurio labeled Kalanchoe peteri. As it didn't match the description of this species Bleck speculated that it was actually Kalanchoe rosei or a hybrid involving this species and possibly K. daigremontianum or K. tubiflorum. All of these species are ones that were once placed in the Bryophyllum genus and produce plantlets on the leaf tips as this one does - this plant has the foliage more like Kalanchoe daigremontianum but with flowers more similar to K. tubiflorum. We were certain that this plant had a valid cultivar name could only call it by the name of the person we first received it from. We have since been filled in more on its origin by Ed Mercurio, who noted that he originally purchased the plant in the 1970s from Kelch Cactus nursery in Prunedale and thought it might also go by the name 'Arrowhead' in reference to the leaf shape.
The information about Kalanchoe 'John Bleck' 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. |
