I wouldn't try to attach a cultivar name but agree that it looks like K. blossfeldiana. Did the plant decline or just stop blooming? They bloom seasonally, during the shorter days (if you are in the N hemisphere.)

During the shorter days if you are in the S hemisphere too. ;-)

LOL! That didn't come out right, TY for the help. :)

looks like a florist plant .. forced in greenhouses for sale when in full bloom ...

many such.. are not really easy to keep growing ... as sometimes they are dependent on the perfect conditions in the greenhouse ... and we end up treating them almost like cut flowers ... the word ephemeral pops to mind ...

that said.. i would take the latin name to a search engine.. add the word propagation .. and see if i could make more ... increase my odds of keeping some around:

i would also see if i could get some of those outdoors ... and at least grow them outside for the summer ...after hardening off.. etc ....

and i would just enjoy the beegeebees out of it... and not get all wound up.. in worrying about whether i could make it an indoor forever plant ...

you might want to ask in the houseplant forum.. if anyone has had long term success with such ...

IDK why any greenhouse or florist would need to make any effort at forcing, unless they're trying to get blooms during long, hot days. These plants bloom very reliably, predictably. I don't get to stores where plants are sold much anymore, but have only ever seen them for sale in the spring, when they would naturally be blooming. Thank goodness this insistence on selling only while blooming is not extended to all plants.

As with other florist pot crops forcing would be to get flowering at times other than the natural blooming season. Reliable post purchase flowering of this kind does not seem to be the general experience, with many appearing to have specimens that go on for years thereafter without blooming. And references discussing the culture of the plant describing specific conditions being required in order to induce flowering.

I understand the theory, TY. It just does not apply to K. blossfeldiana with the normal bloom time coinciding with when they are sold. After having observed hundreds of specimens in various conditions such as various amounts of light, various temps, I can see that there is no special condition required for blooming, I don't even fertilize plants except very sporadically over summer, and don't usually get around to giving any to succulents, ever. While not outside over winter, most get some direct light, but not all. The one winter I put plants above my shower with no light except 8 hours of a fluorescent shop light about 3 feet above the plants, the K. blossfeldiana individuals in those pots bloomed. Some plants are kept in barely above-freezing shed over winter, some in unheated rooms of house, some in rooms where the heat can be around 80 over winter. What else would forcing consist of beyond a specific temp range, unusual amount of light, being fertilized?

Are you able to provide a link to a reference describing these specific conditions?

I have no way of confirming but it's my assumption that those plants that do not produce further blooms past the initial blooming occurring when purchased/given, are getting too dry, are in never-replaced soil that is too infertile (and not fertilized,) just in a darker room/spot, or experiencing temps outside of the range between about 35°-80°F. So many people post pics of their Kal plants re-blooming in forums & other online groups, it's extremely common, downright pedestrian.

This Powerpoint describes the necessary day length criteria for blooming.

These things are sold all year round here so flowering is definitely manipulated by growers. As well as bloom time, height is also manipulated using chemical growth regulators. Older plants kept at home lose their compact habit quite quickly.

Names:

Flaming katy (common). -- Kalanchoe blossfeldiana (botanical/scientific).

THANKS THAT'S IT !Max Growth (approx):18 inches in height.Poisonous for pets:

Toxic to cats and dogs.

We have 2 small DOGS that share the bay window with this plant ( only sunny window) . Time to toss it !

Probably for the best, John, if you can not find anyone who would give it a home. There are plenty of plants that would be harmless to pets. The ASPCA website has a reference list for that kind of thing. Good luck!

Thanks for the comments and link, Flora. The information seems to be aimed at professional growers, and doubtlessly perfectly outlines a foolproof plan, but the parameters are unreasonably tight for a home grower to try to follow. From the number of people who post pics of blooming plants regularly, not necessary to follow such a stringent regime.

No room in my house stays within such a narrow range of temps over winter, with heat only being on in rooms where people occupy at the time, then turned off for the day if nobody is home. From what I have observed, temps are irrelevant, as long as they are above freezing.

This may be trying to pick gnat poo out of the pepper but it seems like really long days cause blooming to stop, as a more strong factor than shorter days causing blooms to begin because the blooms usually last for 7-8 months. The really short days of winter don't cause the blooms to stop. I've only had this species in south AL so if high heat is also a factor that causes blooming to stop, I have no way of comparing with more moderate summer temps. It's 94 today.

In regard to compact habit, a cutting has to grow. Lack of etiolation can be achieved with plenty of direct light. That's all one can hope for, since a plant can't avoid aging and growing, but taking cuttings often & discarding the lignifying stump could be an option for those who want to maintain the tiny plant look that one might get if starting with a small, short plant. Otherwise, they start to look like a tiny tree, with a trunk and many branches, if kept in enough light to stay upright. The first one I got was already a foot tall with enormous, shade-grown leaves. Significant direct sun yields much smaller leaves.

Do you (or others, any reply welcome) think "postharvest" in the quoted point below means after being taken
from the grower's nursery / greenhouse to be potted & sent out for
sale? I don't know what other harvest there would be. "Especially valued in Europe for its long lasting postharvest quality"

I imagine 'post harvest' means flower duration once the buyer has taken it home. Personally I've never had one rebloom.
