This little thing is still with me, despite neglect and general mistreatment. It seems very easy to care for. The pictures are from its second blooming since I got it (I've had it for...eh...some time, which I can't remember), where it got two spikes, the first with four flowers (the pictures), and the second with three. It's in spike again, but with five (!) spikes this time.
I love this little Den. and I'm so happy I managed to get a hold of one.
