Plant is from Altman Plants, Vista, Ca. and the label reads: Kalanchoe hybrid 'Behartii'
A hybrid between Kalanchoe beharensis and Kalanchoe millotii that forms shrubby stems with frosty green leaves with marginal serrations and cinnamon markings along the margins.
I cannot find any exact information regarding a cultivar by the name 'Behartii' and some sites say it is incorrect, that the plant is actually a cultivar hybrid of K. tomentosa ...
