Growing miniature orchids is a very worthwhile adventure. Not only are there so many to choose from, each with their own unique features, you can fit so many more into a small window. You can also sneak them in here and there around and on top of your larger plants if your space is getting slim. Today I'll showcase two cuties for which I have a couple plants available to share.
The first is Neobathiea filicornu, an angraecoid species with a leaf span of around three inches topped by a cute white flower with a long nectary and nice large lip. This is a rarely seen species for all you angraecoid enthusiasts out there. I keep this plant in our cool to intermediate basement under fluorescent light year round. Blooming seems to coincide with humidity peaks (i.e. foggy windows) in our basement, but I don't know if such a humidity spike is required to induce blooming.
The second is Dendrobium rigidum, or at least that's how I know it. If you lookup rigidum online you'll find some other images. But these plants came to me as rigidum, and I have a friend who has been growing a few plants of this for several years also with the name rigidum. So we're sticking with rigidum for now. Anyway, the species has the neatest succulent foliage. Leaves are 1 to 4 inches tall, and very thick with a rough texture. These are adorned occasionally with slightly fragrant cream flowers with red markings. The plants are fairly easy to grow in an East or West facing window and make great mounted specimens.
