Arbor Day Foundation from Nebraska, USA

I give this supplier 2 out of 10 acorns.

Website is slick, it is a big production.
Prices are generally high for small landscape plants. Sometimes they will have a deal on a package that might look worth it.
Delivery is whenever they are shipping to your USDA zone, which is much later than I usually plant.

The big problem is the stock.
Quality is poor. I ordered some hawthorn and crabapple, and both were visibly diseased. The plant inspection must be cursory. The hawthorn was not a hawthorn. It appears to be a pear. The crabapple suffered 50% mortality immediately because the roots were moldy.
My big beef is the "thornless honeylocust" had visible large thorns on delivery. How they screwed that up is beyond me. I had only a few that had small or absent thorns out of 10. Some plants in the family will make thorns under browsing pressure, but these came installed.

I will not order from them again.
