Do you have a garden store near you? If so go there and look at what they have. I always prefer buying plants I can see over those I cannot and prefer plants I can drive home over those that are mailed in boxes.

Having said that I don't know of any online store that offers everything for anything. It is always something from here, something from there.

Try glasshouseworks.com- reasonably priced for most of their philos. They've a wide selection of beautiful philos. The ones that are very expensive, are also very expensive elsewhere online. The best bang for your buck is always going to be your local greenhouse.

I've ordered aroids from them before and was pleased.

I see you're in N. TX too! =) You might want to try your local Calloway's. They're pretty good about carrying a wide range of named plants, and will sometimes seek out specific plants that you're looking for f/their growers. It's worth a try!
