Many thanks, Tarev and JB. I have decided and prepared to move in my confed (together with 5 big Aloes + 12 baby aloes) when winter cold and rain come.
Oh, JB: I am pretty sure that I got a confed by looking its flower. The petal is not as long as star and the edge is not as smooth. And it has a yellow color around the hole in the center of the star shaped flower.
