Description

‘Emerald Blue' creeping phlox (Phlox subulata) delightfully welcomes spring with lush foliage and hundreds of blooms. This ground cover forms a low-growing carpet that spreads vigorously and adds color year-round. The flowers are so abundant in the spring; you can barely see the foliage underneath! Delicate, star-shaped blue flowers are fragrant and adored by butterflies. Though the flowers look delicate, this plant certainly is not! It's highly adaptable and able to thrive in challenging sites, including gravelly soil. Plus, it's unbothered by deer. Try planting in rocky areas, on steep slopes, or as a border, and it won't disappoint!

Details

Botanical name: Phlox subulata 'Blue Emerald'
Common name: Creeping phlox
Zone: 3 - 9
Sun exposure: Sun (> 6 hours sun)
Height x width: 4-6" x 24"
Flower color: Purple, blue
Foliage color: Green
Season of interest: Late spring and early summer
Bloom time: Spring, summer
Features: Winter interest, suitable for slopes, space savers, rain gardens, heat tolerant, ground covers, drought tolerant, deer resistant, best sellers

How to Grow

Soil: Well-drained soil enriched with organic matter. Plants prefer soil with a slightly acid to neutral pH.
Light: Phlox grows best in sun (> 6 hours sun).
Water: Low to Average.
Spacing: 18" apart.
Fertilizing: Generally unnecessary, but a slow-release granular fertilizer worked into the soil around the plants in the spring is sufficient.
Winterizing: No special care is needed. Leave foliage standing in winter, and clean up spent foliage in spring.
Maintenance & Pruning: Cut back stems after flowering by 1/2. This will maintain dense growth and attractive habit for the summer months. This will also encourage some fall rebloom. Cut out any brown stems.

All About: Caring For Creeping Phlox

Creeping phlox (Phlox subulata), often called moss phlox, mountain phlox or moss pink, loves sun, tolerates drought, attracts butterflies, & even resists deer. This superstar ground cover is great for gardeners of any skill level; if you’re looking to add easy-care color & interest to your landscape, consider making creeping phlox your next garden addition.

Grow with confidence

Plant spacing is based on the ultimate width of the plants. This figure is normally given as a range; for example, 3-5’. If you live in a cold climate and/or want plants to fill in more quickly, plan to space at the shorter end of the range. If you live in a warm climate, are on a limited budget, or are willing to wait longer for plants to touch, use the higher end of the range. Using the larger number is recommended when calculating distance from a building or structure. There’s really no such thing as "maximum spacing": if you don’t want your plants to touch, you can space them as far apart as you’d like. All plant spacing is calculated on center, or in other words, the centers of the plants are spaced one half of their eventual width apart:

bush distance

Unless you are planting in a straight line, as you might for hedges or edging, space your plants in a staggered or zig-zag pattern for a more interesting and naturalistic look:

bush distance zigzag

Not sure just how many plants will fit in your garden? Our calculator gives you the exact amount of plants required for your space. Simply update the values and the calculator will re-calculate accordingly. Spacing information can be found in the 'How to Grow' tab on each plant's page.

Terrible waste of money purchasing these

Terrible waste of money purchasing these. The plants I received are tiny. Basically paid for a quart of potting soil and a tiny seedling. I purchased a dozen of these -all smaller than I would expect for “plug” size- definitely not what anyone would expect when purchasing a quart sized plant.

We’re sorry you’re not satisfied with your plants! On each product page and our plant sizes page, we note that all of our plants are young. The size of our plants varies depending on the time of year and whether they were recently trimmed. The most important thing when purchasing plants, online or in garden centers, is a full and robust root system, which we prioritize. Trimming only encourages stronger root development!

Disappointingly small

I'm not sure if this is a mistake. This is all I received for $16. A lot smaller than what others received. This just can't be right.

Hello! We’re sorry that you received plants that are not up to our standards. We try our best to provide excellent plants, but some factors, like shipping and handling, are outside our control. That’s why we have a 60-day guarantee on all of our orders. Please email your order number and pictures of your plants to [email protected] to start the claims process.

Still unsure

These arrived on April 25th and continue to struggle to become established. With the drought here, I water them daily as they are looking brown and struggling. Hopefully they will grow well.

Our friendly customer service team is here to help! Browning in the center of your creeping phlox could be caused by excess moisture which could be caused by the pine needles surrounding the plant in addition to watering everyday. Our expert horticulturists would love to take a closer look. Just contact us at [email protected] with your order number and photos of the plants. After further investigation, we will be able to better assist you. All orders are covered by our 60-day guarantee. We appreciate your feedback and look forward to helping! https://bit.ly/ggp-guarantee

Not what I expected

The plants arrived well packaged and over watered. We followed all instructions to keep them watered daily with partial sun until planting yet they developed mold in 3 days and 10 days later all 3 pots were dead.

Mixture of Creeping Phlox and Hardy Geraniums

We planted ‘Emerald Blue’ Creeping Phlox plants between ‘Apple Blossom’ Hardy Geraniums to provide a contrast of colors and to fill the bare spaces more quickly. Plants arrived in good condition. All of the plants have become established and appear to be growing well.

Incredible for patio borders

I purchased several of these for a border coverage for my patio beds, and they are simply "Fantastic". I live near Indianapolis, and just wish they bloomed year round. Definitely worth the purchase!

Hi Chuck, thank you for sharing a picture of your gorgeous landscape with us! We're so glad to hear that you're happy with your Phlox. Happy Gardening!

They arrived looking healthy, but looked like the same size as the plugs I previously ordered, but in larger pots.

Not as expected

Each pot had 1 tiny little vine, no flowers in it, abiut the length from my pointer finger to my thumb. What a rip off. And they were spilling out everywhere in the shipment.

Disappointing

I planted a handful of these in a few places around my yard (three pink, three blue). They didn't look great last year after planting. All three have not returned this year.

I bought out of flowering season but the plugs were incredibly healthy with great root systems. Took to the spoil perfectly. Can't believe how fast they came, less than 24 hours!

Not sure yet

Came healthy, still healthy looking. It’s been a year and it’s not even doubled in size. One got three flowers this spring and the other got one. I hope it kicks in high gear soon.

Thank you for your feedback! It’s surprisingly normal for newly transplanted plants to appear like they aren’t growing. That’s because most of the growth occurs below ground in their first year as they allocate more energy to root development. Once your plant is established, it will start investing more in shoot and flower development.

Landscape Plugs very high quality!

I buy a decent amount of by-the-flat plants online and the quality of these plugs was through the roof. Well packaged in deep cells and very strurdy trays, lots of vigor, excellent root development, only 3 'dud' cells across 4 trays. I got everything in the ground and they look happy after 48 hours, looking forward to the growth!

Rabbit food

Unfortunately I cannot give a true eval. Within 2 weeks if planting, I think.... Rabbits ate most of them.

We're sorry that the rabbits enjoyed your plants before you could. Young plants are especially susceptible to rabbit damage, so we highly recommend protecting new plants in areas with high rabbit traffic.

Love these!

Super hardy and quick growing. Seem to be almost an evergreen even in zone 3 if protected with snow over winter.
