Portland is nice and misty and mostly cool, some Bulbophyllums, or masdevallias might be perfect. (My mother lived across Jansen (?) island in Vancouver, WA.) I am also a fan of planted tanks. I have a 75 gallon tank with lots of anubius and buce. My latest triumph was some white anubius nana-- very slow growing. It takes about 4 months to double. You have Seattle Orchid near to you. How lucky you are. Also some great aquarium stores!
