Kalanchoe 'Pink Butterflies' is an incredibly сolorful, variegated form of Kalanchoe x houghtonii. The original hybrid is a cross between Kalanchoe daigremontiana and Kalanchoe delagoensis. The difference between the parent plant and K. 'Pink Butterflies' is that both parents of the original hybrid are "viviparous," producing hundreds of tiny plantlets on their leaves that readily fall from the parents and take root with little to no effort. K. 'Pink Butterflies' while still producing copious quantities of tiny, pink, butterfly-like plantlets on its leaves, have lost their ability to root from plantlets. Sometimes a couple might take, but in general, no. They are pink because they lack chlorophyll. Thus like any variegated plant that lacks chlorophyll, they Simply die.
