Thanks for your question. Orchids come in so many different varieties and styles that we cannot list all of them. The difference between standard, medium and large is basically the variety. Standard would be a basic, most likely single stem orchid plant. As you upgrade to medium or large, we have fancier orchid varieties with 2 or more stems. Whichever you choose, we will pick the nicest variety in that price range. If you have any special requests, you can always enter that at check-out in the special instructions field. Feel free to call, email or live chat with us with any additional questions.
