Yamamoto Dendrobium nobile in Bloom. 3.20.18

These are Yamamoto Dendrobium nobile hybrid orchids that I've had for, maybe, 10 years. During the summer, I just sit them under a tree. During the winter, I keep them in the sunroom, although any sunny window would do. This is when they bloom like crazy. I gave them a little diluted general plant food in January. Super easy to grow and maintain.
