Central America.  B. nodosa has been used extensively for hybrids, but even on its own, it will produce flowers whenever it's ready, without a special season! And it's fragrant...during the night! B. harrisii is fairly new to collections and not very common. Flowers are smaller than those of B. nodosa, and will form many clusters of flowers, with fragrance! Flowers are green with white lips and very attractive. Available in 2" pots.
