Yup, it is just green while in bud..then it becomes into a peach/orangey color or is it the pink one..sorry not sure which color it will make my similar kalanchoe has not bloomed for me..it just makes babies which I often find here and there
It will enjoy a bit more sun now that it is in blooming mode. And I prefer that it will not make blooms.
Hope you can position it by your sunniest window. Enjoy the bloom show formation, as I understand it, kalanchoes are monocarpic, meaning it is at the end of that plants life. But hopefully it will make many babies first before it goes.
