Thank you so much for these lovely hardy kiwis. They are much bigger than expected. Will be ordering from you again.

I have been buying from your nursery for years, and hands down your citrus has survived the best out of all of my sources. I have never lost a plant in my colder climate.

It looks like it is at least 7 feet tall. I certainly was not expecting it to be that big.
