Many of us like compact orchids because they fit nicely into growing spaces like windowsills and tanks, plus you have room for more of them. While I love minis, most of my favorite plants are the BIG ones. Here are my favorites in no particular order: 1) Vandopsis gigantea; 2) Vandopsis lissochiloides; 3) Dimorphorchis lowii; 4) Vanda merrillii and 5) Vanda suavis.
