I bought this little gem last summer. Put it into a semi-hydro setup using lava rocks and pumice as substrate, and it just sat there doing nothing for months; but finally, it began to send out new growths and flower spikes couple of weeks ago.
Mine developed some deep purple tinge on the leaves, indicating it had received more than enough sunlight...but so far there is no sign of sunburn or damage, so I am going to keep it as it is for now...it looks pretty btw.
