Moss Phlox ‘Emerald Blue’ (Phlox subulata) is a spreading, sun-loving phlox that only grows up to 6” tall but spreads up to two feet. It is noted for this creeping, moss like appearance and growth habit and it’s profuse carpet of butterfly attracting early-spring flowers. Best grown in medium moisture, well-drained soils but will tolerate drought as well as deer, erosion, and air pollution. It prefers somewhat dry, rocky, or sandy places, open woodland areas and slopes. They are quite attractive to butterflies and other insect pollinators, and a good source of early-season nectar, making it a lovely addition to any garden. Common uses of moss phlox are rock gardens (as it will naturally drape nicely over the edges of rock walls), edgings, foundations or as a ground cover. It is especially valued in sunny areas of woodland gardens, slopes, native plant gardens or naturalized areas.

“Emerald Blue” is essentially the same plant as the standard Moss Phlox, except that it’s flowers will have a blueish tint when it blooms.

Shipping Information

At Direct Native Plants, we take many precautions to make sure your plants will arrive in the best condition possible.

Our perennials are grown in a 4” quart-sized pot. These plants are then cut back to fit our packaging, placed in a protective clamshell container (made from recycled materials), and then shipped to you in a cardboard box. PLEASE NOTE: Perennials can be shipped in bundles up to 6. After that we start a new package, so keep this in mind if you’re trying to get the best shipping rates.

Trees and shrubs are grown in a 7” tall container (referred to as a 1-gallon pot), and depending on the species will be between 12” and 36”. We bag the root section of these plants to prevent them from drying out in transit and ship them in a tall cardboard box. PLEASE NOTE: Trees and shrubs can be shipped in bundles up to 4. After that we start a new package, so keep this in mind if you’re trying to get the best shipping rates.

Direct Native Plants now ships via FedEx. Orders ship out Monday through Wednesday of each week, and depending on how close you are to our nursery in Maryland, shipping will take anywhere from 1-4 business days.
