This miniature vandaceous blooms reliably every summer, given a front row seat in a kitchen garden window, and moderate watering. This year, it pumped out two spikes, with two buds on each.
This is a primary cross that first bloomed for me in late Spring. The flowers have the Christensonia size and coloring, but with a smaller, less frilly lip. Being as far North as I am, I tend to have trouble with full sized vandaceous orchids over the winter, but miniatures do very well for me. It probably has more to do with being potted vs. in hanging baskets than it does plant size, per se. For a first bloom, my verdict is “not bad.” They only get better with age. The entire plant is only about 7″ tall, so far.
