While I had a family emergency and was away for a few months, I had my ever never flowering Amaryllis bloom!
I have tried placing the plant under all kinds of position and had given up assuming maybe I have a rare kind of Amaryllis that never flower. I had them uprooted the bulbs because the leaves withered away and I gave them one last chance and moved them into a tiny pot since it is going to be only foliage.
The position I put the Amaryllis plant now will get exactly about 1 hour evening sun, the one that wont hurt anyone even if you stand in the heat for 20 minutes straight. That is the exact same position that the Amaryllis plant wants to live in, apparently.
