  • US Perennials: Great Plants, Great Customer Service! 5

    Posted by Lisa Mundy on Jul 04 2022

    The plants in my most recent order from US Perennials arrived in perfect condition. Their method of packaging the plants is the best I’ve seen from any nursery, and I’ve ordered from a lot. Plant selection is great, and the website is highly informative. Order with confidence!
