Den. spectabile can be a small grower and Den. aggregatum is a compact grower. Lots of the Dtps. are small and I do grow the Phal. equestris, Dtps. I-Hsin 'Sun Beauty', Phal. Hitomi Watanabe, and a few other compact/sub-compact ones.
I have added the "Window Sill Orchids" page to my site but it will take some time to populate it. It looks like I will have at least 40 varieties on that one page.
