This is a comparison of two kalanchoe's I own. The first is a cutting of a 40+ year old mother plant and the other is one I bought from a market last summer. The heirloom grows as more of a vine than a normal kalanchoe. I just thought this was interesting and would like to share :)

That is interesting. Are the two plants kept in the same exposure? I wish I could see more of what you're referring to in the pics, but it's hard to complain about such gorgeous blooms taking up most of the images!

Great growing!

With the close up shots, I cannot see the difference in the two plants either but they sure are gorgeous! Usually Florist Kalanchoe (Kalanchoe blossfeldiana) has an upright, branching habit but if the one growing more as a "vine" is receiving insufficient light, it could be "stretching", trying to reach the light ... or, it's possible that there's a trailing variety I'm not aware of.

Both are in a southern exposure so I doubt it's etiolated. Heres some other pictures.

Unfortunately, I can't really grasp the vining habit of the heriloom one, but they're both stunning!

They're both beautiful!
