This is a very vigorous growing reed-stemmed Epidendrum.....and one of my favorites of it's genus. I currently have about 200-250 seedlings of it's offspring from a little cross I made with Bl. Richard Mueller...they are not even a year old, and most are already 6"-8" tall (they got that from their momma!) The plant pictured is a little over three feet tall. It seems to do well in bark or soil....or just about anything, as long as it gets lots of light.
