I got my first Clivia miniata 'Solomone Hybrid Yellow' last Nov 2014; repotted and placed it by our front door protected by an alcove in case it rains. I left it there not giving it any water, just letting it get that cold treatment it needed. I know we had one day in Dec where we had a freeze warning, but I was away, so when I came back in January, I pulled the plant indoors. I have placed it now by our north facing window.
After a couple of days, I gave it some water, not a lot. Then I noticed it started showing new offsets. And today, 23Jan2015, I see some buds forming at the center of the main plant. It is a total surprise for me, but that is just what I did. Nothing much about fertilizers even. I guess the plant is just mature already to start making flowers. To be honest the existing leaves are not that impressive, looks tired and somewhat wrinkly, but there are new leaves from the center that are newer and more shiny. Temperature inside my house is set at 60 to 68f range.
I counted the leaves this plant has 11 leaves right now.
From my readings, Clivia does take awhile to bloom if it is still too young. I guess I just got lucky my plant is already quite matured and the timing to let it do a cold dormant rest that it needs so now it is ready to bloom. I was advised that at this point, I can start giving it more water, because sometimes the spike stalls inbetween leaves. So I will observe how it goes and if it does that, that will be my remedy.
So maybe for those with problems having it bloom, the cold treatment aspect is what needs to be improved and got to keep it really dry while doing the cold treatment. It has such fat noodle-like roots. It can take the dry conditions.
