Within a few days of our order, we had beautiful, healthy plants delivered to our yard. Talk about a pleasant surprise to have everything we asked for unloaded and waiting for us when we were ready to plant without having to leave the house.

An amazing resource for plants, advice and landscape expertise. ServScape designed a rooftop garden for me which included the design, sourcing the planting materials, and installation, including a small irrigation system.
