All ship times are subject to change if extreme weather conditions are present here at the nursery or at the shipping destination.

Please note: Depending on the time of year, the foliage of the plants may be trimmed to fit into our shipping boxes. This could delay the flowering of the plant, but many perennials actually benefit from being cut back.
