in the house and out

My purple-edged pink african violet is almost done with this round of bloom. The purple edges seem less distinct than before...

The other two violets are forming buds, so I might have all three briefly flowering simultaneously

I gave up on keeping the sensitive plant mimosa indoors. I don't know why they always yellow and die on me. Last time I looked up info, found suggestions that it has to do with the water temperature. I pay attention to that now- but it still drops yellowing leaves. I put it outside on the deck to see if there's any improvement with another site change.

Also my lithops appears to be in bad shape. I was all ready to start watering again when the last of the old leaves withered away- but it started growing another set of new leaves. And they are all small, leggy, unhealthy-looking. The pot isn't in a good spot- it has the most sun, but also as you can see gathers dust too easily. I am not sure what I can do for it at this point. Might be another plant I'm just no good at keeping.
