while I agree to some extent - I would mention - that if you have trouble with one type of orchid - even if it's "supposed" to be "easy" or "beginner" don't be afraid to try a different type.
After a few years of orchid growing I am just now getting the hang of Phals - easy for a lot of people, but not me I guess
But probably is a good idea to not go way overboard with lots of different alliances all at once while you are starting out. But even within alliances, even within genera, some plants will be easier or harder to grow than others - and some will be easier or harder for individuals depending on their care habits and climate.
That said - Phalaenopsis is a good place to start - just don't feel you can't grow orchids if you have trouble with them. Every one here is happy to help with questions you may have - or if problems arise.
I'm sure others can answer your questions regarding reading and frequent bloomers
Tho - I would recommend as general orchid books for beginners - "Orchids for Dummies" and "Ortho's
Complete Guide to Orchids" (Ortho has another much less informative orchid book - so if looking for this make sure to look for the
Complete Guide to Orchids
Orchid shows are great for buying orchids - usually from reputable vendors, and no shipping charges! lol You can search online for any Orchid societies in your area, and then look when they may have shows.
Many of us started with box store and grocery store plants - and good ones can be found in those places - just sometimes they have been sitting a long time in soggy potting media and so may have no roots left by the time they are sold. I still buy plants at Trader Joe's, a local hardware store chain, and a garden center. Just do not succumb to the impulse to "save" a sorry looking plant, and try to buy only ones that look very good.
There are lots of excellent online vendors as well, and I am sure board members will be happy to point you in the direction of their favorite vendors
