I am doing my best to "branch out", no pun intended, and obtain a more varied collection of orchids. I have a batch of vanda, gramm., dtps., den., and mtssa. (all "baby" or "teen" plants) and have several varieties of terrestrial ones that I am trying my hand with. Of my 600 or so plants, 2/3 are still cattleya alliance ones.
One thing I find most interesting with vandas, is their roots. I only have two mature plants, and while their flowers are nice, but not fragrant, the roots are all over the place. One in particular, a purple NOID, has the most unusual root formation I have ever seen. Since I don't grow lots of vandas, I am not sure if the roots are all that unusual. But those roots are bizarre when compared to cattlelas.
