Expert delivery: healthy plant

Healthy on arrival is exactly what we aim for, Linda. Blackhawk Big Bluestem is a great choice, and once it settles in you should see that deep burgundy fall color really develop over the seasons. Thanks for sharing your experience.

Very Expensive & Poor quality!

When it was delivered it was totally dead looking! And there has beenNo signs of life yet🥲
Hopefully it will do a rebirth for next year, because I didn’t purchase the warranty!

Poor quality and crappy customer service

I ordered these. When they came it had like 5 blades. I don’t even know if it’s going to make it. I paid $149 for 4 of them. You can’t get ahold of anyone at nature hills through email, calls, or texts to get it taken care of. And 2 of my plants I ordered with these did not even come. And like I said can’t get in touch with anyone to get my money back.
