You would need to check locally to see what the different stores have in stock. Otherwise there are some speciality mail order houses that would offer a selection for example

Keep in mind that the term dwarf is a relative term and so while the plants may grow slowly and mature to a smaller size than is normal for their type, very often they can still grow to be quite large over time. Your local professional nursery staff and cooperative extension can help you determine which plants might be suitable to the location you want to plant. Enjoy your little trees!
