Eastern white pine, P strobus, is a frustrating species for bonsai. You will get a wide range of reactions to this question, some surprisingly emotional, the degree of emotion will be directly proportional to the number of years the poster tried to get P. strobus to become bonsai. In theory, they should be good bonsai, in practice, they are endlessly frustrating. I know, I have 3 right now, and off and on over the last 35+ years have had zero success creating acceptable bonsai with P. strobus. One tree I worked for 25 years before composting it. There are a small handful of ''good'' P. strobus bonsai, but they were collected trees, near a century old, very rare and very special. P. strobus is a very poor choice to learn bonsai with. It will frustrate you. If you collect an old, but still small specimen of P. strobus, you may have a better chance of success. It needs to be old enough it already has rough bark forming on the trunk, meaning most likely over 40 years old. Hard to find 40 year old trees that are still small enough they can be successfully collected.
Osoyoung, and a few others have select grafted cultivars of P. strobus that behave different, and much better for bonsai in that they tend to break buds more easily than the type form of the species. Some of these mostly dwarf cultivars may indeed become good bonsai, but most that are working on these cultivars have not had them long enough to be ready for the ''show circuit'', so basically they are too young to pass a conclusive verdict. The ''wild form'' of strobus will frustrate most but the most skilled of bonsai artists.
Your climate is mild enough, you should be able to grow Japanese black pine, Japanese white pine, Scots pine, and many many others, all are better choices. Japanese white pines are not the easiest pine to learn, Scots pine is probably your best choice. Mugo pines are also a good choice, but you need to follow a slightly different calendar than the old books recommend, read the thread ''all aboard the Mugo Train'' if you want to learn to do Mugo pines. There is also a resource page dedicated to mugo here on the BNUT site.
