Products > Kalanchoe 'John Bleck'   Kalanchoe 'John Bleck'     [2nd Image] Habit and Cultural Information Category: Succulent Family: Crassulaceae (Stonecrops) Origin: Madagascar Evergreen: Yes Flower Color: Orange Red Bloomtime: Winter/Spring Parentage: (K. daigremontianum x K. tubiflorum) Height: 1-3 feet Width: 1-2 feet Exposure: Full Sun Irrigation (H2O Info): Low Water Needs Winter Hardiness: 25-30° F 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 labeled as Kalanchoe peteri but as it didn't match the description of this species he speculated that it was actually a hybrid, possibly between Kalanchoe daigremontianum and K. tubiflorum.. Both 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 are certain that this plant has a valid cultivar name, but until such time as we discover what it is, we are call it by the name of the person we received it from.  The information provided on this page is based on research we have conducted about this plant in our nursery's library, from what we have found about it on reliable online sources, as well as from observations in our nursery of crops of this plant as well as of plants growing in the nursery's garden and those in other gardens. We will also incorporate comments received from others and welcome getting feedback from anyone who may have additional information, particularly if it includes cultural information that would aid others in growing  Kalanchoe 'John Bleck'.     [MORE INFO]
