ok this is the other plant (the same) but this one is quite larger than the one first pictured, the first one was actually a division that went off of this plant, and bloomed several weeks before this one.
i do have this one growing in my backyard in a tree, only nature providing it what it needs, it is a cold grower, but i believe she also thrives in intermediate temperatures.
edit : there are a bunch of spikes that has not opened and are still forming.
