I am glad to see this - I had a flask about ten years ago , and struggled with the seedlings for years , but they never liked my conditions and all faded away, one by one.. I shall have to look out for a BS size plant. It is very nice.
perhaps the flowers are not long lasting, as is so often the case with these South American things ? Not that this would deter me, as long as "not long-lived" gives me a week or so.
