Oh wow! I had no idea you could buy live plants from Zulily! Some even come with a warranty! Some as low as $12.99! This ships to you when it's time to plant in your area!
You will have to pay shipping for the first item you check out with but after that you should have free shipping for the rest of the day on Zulily (not completely sure if this works for plants tho- let us know if you know!)
