    Phlox subulata 'Emerald Blue' gives a unique gift of abundant deep-blue flowers on a thick mat of low growing needle-like foliage. Use as an edging in flower beds with spring blooming purple and reds to intensify the blue blooms. Phlox subulata 'Emerald Blue' is native to Eastern U.S. and will naturalize in a sunny, well drained spot. It will cascade slightly and looks luxuriant pouring over the side of a short retaining wall or garden trough.

    Shipping Methods

    Orders will be shipped via FedEx Home Delivery.

    Orders are generally in route for 2-5 business days (depending on where you live).

    We are sticklers about packaging and shipping your order in a way that guarantees healthy plants upon arrival. If plants are damaged on arrival, just let us know and we'll send you new ones or offer a full refund.

    All of our plants are container grown and shipped with the soil and roots fully intact. We DO NOT ship your plants bare-root. Being shipped as a containered plant greatly reduces the risk of the plant not surviving the transit to your home.

    excellent!

    I love these! They bloom for a LONG time. Unfortunately in the last year, the rabbits ate them down to the ground. I don't know what to do!
