The Emerald Blue Creeping Phlox has amazing purplish-blue color that really pops in your landscape. This native groundcover offers distinctive beauty and year-round interest that is hard to beat!

Lavender blue flowers smother this pretty and petite phlox in spring. This evergreen shrub is lush and deep green with petite, slender leaves. This variety is also known as moss phlox as the foliage has a resemblance to moss. Emerald Blue Phlox reaches a mere 6 inches tall at maturity, but it spreads to 2 feet wide. This perennial is vigorous and low maintenance.

Avoid mowing! Plant creeping phlox instead of grass in hard-to-mow areas.

Emerald Blue Creeping Phlox are lovely groundcovers. These plants have a low, spreading habit that becomes mat-like over time. Plant in mixed beds, rock, woodland, and cottage gardens, containers, low walls, and next to walkways. This phlox cascades like a waterfall over edges and down slopes if you like or trim them for a tight, clean edging. Plant in mass for a cool pop of color and a unique grass substitute.

Caring for Emerald Blue Creeping Phlox

Spring and fall are ideal times to plant your Emerald Blue Creeping Phlox. In cooler zones summer is a great time to plant as well. Phlox can grow in zones 3 to 9.

Phlox thrive in full sun and prefer moist, well-drained soil. Some subtle afternoon shade may be ideal in hot climates. Water deeply when planting and 2 times per week for the first 3 months while your plant is establishing. Once established, Phlox are drought tolerant. Add 2-3 inches of mulch to prevent weeds and protect your plant's roots in extreme temperatures. Fertilize with our slow release fertilizer when planting and in spring for best results. Deadheading isn't necessary, but it can increase blooms and extend bloom time. Phlox are deer resistant and salt, pollution, and erosion tolerant. Creeping Phlox tolerate rocky and sandy conditions.

The best way to prevent disease and pests is by providing the appropriate care for your plants. Proper location choice, air circulation, watering, and fertilization are the keys to your success. Phlox don't tend to have a lot of issues with pests of disease, but because they grow at ground level there are a couple things to watch out for. Mites can be treated naturally with neem oil, or insecticidal soap. For severe infections you can use pesticides like carbaryl, also known as Sevin. To determine if mites are an issue look for the foliage to be dull and webbing to appear. Phlox can, on occasion, encounter fungal issues especially when moisture is high and air circulation is low. Neem Oil is an organic method of treating and preventing some fungal diseases and pests. It can be effective, but the entire plant must be coated in order for this method to be effective. Water at the base of this plant to avoid fungal disease on the leaves. For severe fungal infections treat with a fungicide.
