Yes, these two house plants are still on my glassed in porch. They are supposed to be chilling down to about 40 degrees Fahrenheit. Nature isn’t cooperating with me this year, although we will get there eventually. I just hope that I remember to bring the plants in at that point.
Clivia miniata are tough, long-lived house plants. They bloom in flower spikes of orange or yellow in late winter if you can get them to bloom. Otherwise, they might bloom naturally for you in summer–or maybe not at all. That’s why I called them “challenging ” in my title.
To get them to bloom in late winter, the trick is to stop watering in October. Keep them cold. Let them get as cold as 40 degrees.
In mid-January, warm them up a bit (to the mid 60s) and begin watering. If they are going to bloom for you, a bloom spike should form shortly. If it doesn’t happen, continue to water until summer–or whenever you can set them safely outside. That’s the second opportunity for them to bloom.
Clivia like to be tightly potted so don’t repot until they are almost breaking out of the pot.
And if these plants take a year–or two–vacation from bloom, enjoy the lovely foliage!

Houseplant? I grow them in the garden. The yellow sort used to be rare, but then became a fad, and are not more common than the orange.
These can’t stay outside here. In fact–& I should know better because it happens every year–I went out onto my porch yesterday and it was 37 degrees on the porch. The first thing I thought was “yikes! I left the clivia out here again!” But they’ll be fine. They can take one night of that.
