Great Purchase

I bought 5 plants and all but 1 arrived beautiful & ready to plant. I emailed the company about the damaged plant & attached pictures of it. They responded immediately to my email and replaced the plant. I am extremely happy with my purchases and the customer service. I will buy from Planting Tree again & also have recommended them to family & friends.

Blue Dune Lyme Grass

Started with a large pot of this grass an after a few years it declined. I searched local nurseries an on line to add into the pot - never came across it until Planting Tree had it! So very happy Planting Tree online garden center carried it - my large pot looks beautiful again! Thanks, from this Texas gardener.
