A suggestion... mini-Catts. They are extremely forgiving of just about everything... bred for windowsill growing in terms of size, happy outside in good weather but also happy indoors if that's where they are, really don't care much about humidity either. And some brilliant colors, bloom 2 times a year in many cases, Take a look at
Sunset Valley Orchids Great plants, and Fred Clarke (the owner) is extremely responsive, very willing with answers to questions. They do sell out quickly so if you see something you want, buy it and get it held for better weather. You can get the email list for the "drop" of new offerings. Also
Diamond Orchids
