That seems a very dark spot for a plant that wants lots of direct sun.

As to your Question, those are called aerial roots & they're just fine, it's normal behavior for some succulents, especially Kalanchoes (which I believe this is a kind of one).

It's a very rainy cloudy day, otherwise a bright southern exposure...until late spring when it goes outdoors. Thanks for the info :)

Is it the same plant as the plants below (ones with the large leaves)? It is difficult to tell from your photo, but the leaves of the plant with aerial roots look narrower, so it could be different plant. Could you get a close up or top view photo?

Regardless, the roots should be no problem - while they are sometimes signalling certain 'problem', it isn't usually anything too serious. They grow sometimes in humid environment. Or plant may not be getting enough moisture thru the roots. Some plants grow them at all times.

What zone are you in? Even if your window has southern exposure, plants may not be getting enough sunlight. Looks like they are some distance from the window. If that's the case, sooner or later they will start growing longer, skinnier and the leaves will be spaced further apart - etiolated, reaching for more light.

Yes, that's 'Fred'. Great plant.
