Just an FYI in case you guys were wondering like I was, I couldn't find the graft line for my dwarf lemon meyer improved that I bought at HomeDepot a couple months ago and wanted to know if it was truly grafted or just a cutting. I emailed La Verne Nursery (HomeDepot's citrus + other fruit trees supplier) and received the following:

Thanks for your inquiry. It is grafted; the reason you cannot see the graft union is because we do a great job in our grafting!! Thanks again for purchasing our products, we appreciate it. The rootstock is C35.
Richard Wilson - CEO
La Verne Nursery Inc.

To my surprise, I got a reply back from their CEO and found out that it is graft and it looks like they are using C35 (semi-dwarf) now instead of flying dragon. Hope this helps.
