The Kalanchoe species that reproduce from plantlets were moved to the Bryophyllum genus way back in 1805. But, as usual, many did not accept this change or simply ignored it and they have likely been moved back and forth over the years. Plants of the World Online list 45 accepted species in the Bryophyllum genus that were formerly Kalanchoe species. Now, once again, they are back in the Kalanchoe genus. Who knows how long that will last and I will try and keep this blog updated… I have changed the name from Kalanchoe to Bryophyllum and back to Kalanchoe AGAIN. It is highly likely I will have to move it again…

Kalanchoe x houghtonii D.B.Ward is the correct and accepted infraspecific name for this Kalanchoe. It was named and described as such by Daniel Bertram Ward in the Cactus and Succulent Journal in 2006.

Bryophyllum x houghtonii (D.B.Ward) P.I.Forst. is now, once again, the synonym for this infraspecific species. It was named and described as such by Paul Irwin Forster in Austrobaileya in 2006.

The genus name, Bryophyllum, comes from the Greek word bryo (sprout) and phyllo (leaf) referring to the ability to propagate from leaf cuttings…

The original hybrid was known as ‘Houghton’s Hybrid’. It is a cross between Kalanchoe daigremontiana x K. delagoensis. ‘Pink Butterflies’ was a variegated sport of the offspring. Both parents produce plantlets along their phylloclades (leaves) which readily root just about anywhere. ‘Pink Butterflies’ also does this, but the plantlets produce no roots and are sterile. Information suggests this is because they lack chlorophyll.

My ‘Pink Butterflies’ was not originally my plant. I am not into “pink” even though I have more than my share of plants with pink flowers. A good friend of mine, Kyle Hall, bought this plant when we were plant shopping at Lowe’s in August 2012. Then he later gave it to me even though it was at the mansion the whole time. The label said it was Kalanchoe daigremontiana x K. delagoensis ‘Pink Butterflies’.

Family: Crassulaceae
Origin: Madagascar
Zones: USDA Zones 10a-11 (30 to 40° F)
Size: 24-36”
Light: Sun to part shade
Soil: Fast-draining mix amended with grit and perlite or pumice
Water: Regular water during the growing period, barely in winter
Propagation: Leaf or stem cuttings


Kalanchoe x houghtonii ‘Pink Butterflies’

I sold the mansion and moved back to the family farm in mid-Missouri in February 2013. I gave up around 200 plants but took most of my succulents including the Kalanchoe x houghtonii ‘Pink Butterflies’. Whether it was because of the 8-9 hour long trip in 30-degree temps or something else, it died not long after I came here.

I would like to have another Kalanchoe x houghtonii, but not a ‘Pink Butterflies’. I have enough pink in my life. There is one pink thing I am particularly fond of, but I won’t go into that.

I don’t have much experience to share with you, but you can click on the links below for further reading.

I am keeping my eye on Llifle, SucculentGuide, Dave’s Garden, etc. to see how long it is going to take them to recognize Bryophyllum as an accepted genus. Never know, maybe the other side will switch back to Kalanchoe. It wouldn’t surprise me. Maybe the APG group should step in and to a phylogenetic test. Heck, maybe they already have and I just don’t know it.
