Darkest Dendrobium orchid?
We bought this orchid several years ago because of its very dark red purple color. It was so dark it almost looked black. It's very difficult to capture the true color of the flower so the photos are only a pale approximation of what it really looks like. It didn't bloom for a couple of years after we bought it. So last summer I placed it outdoors in dappled sunlight and voila it sent out two flower stalks with many blooms on each. The only problem with Dendrobiums is that it grows so tall it's difficult to keep in our portable greenhouse when the plant is indoors. Also unfortunate that the label is so illegible I can make out only Red Bull? Red Bul.?
