Minimum: 500+ Seeds

Transform your garden into a springtime wonderland with Mountain Phlox (Phlox subulata), a hardy, low-growing perennial that bursts into vivid carpets of pink, purple, and white flowers. Renowned for its long-lasting blooms, dense evergreen foliage, and ability to thrive in challenging sites, this alpine beauty is a favorite for rock gardens, borders, slopes, and spring ground cover. Its cheerful blossoms attract pollinators and bring eye-catching color to early-season gardens, making it a must-have for home gardeners, landscape enthusiasts, and native plant lovers.

🌿 Plant Description
Mountain Phlox, commonly called Creeping Phlox, forms a dense mat of needle-like, evergreen foliage that hugs the ground, growing just 4–6 inches tall while spreading gracefully up to 24 inches or more. In early to mid-spring, the plant produces clusters of star-shaped flowers in vibrant shades of pink, lavender, purple, and occasionally white, creating a living tapestry across rocky slopes, garden beds, or edging pathways.

This hardy perennial is evergreen in many climates, so even when not in bloom, the lush green mat provides texture and year-round interest. Its low-growing habit makes it ideal for filling gaps between stones, softening borders, and providing a polished look in rock gardens. The blooms also emit a light, sweet fragrance, attracting bees, butterflies, and hummingbirds for an added ecological benefit.

☀️ Growing Conditions & Environment
Mountain Phlox thrives in full sun to light shade and well-draining soil. It is remarkably adaptable, tolerating poor, sandy, or rocky soils, making it a perfect choice for challenging garden sites.

• Light: Full sun produces the most prolific flowering; partial shade is tolerated in hotter zones.

• Soil: Prefers well-draining soil; avoid heavy clay that can hold water and cause root rot.

• Water: Moderate during establishment; once established, drought-tolerant but benefits from occasional deep watering.

• Temperature: Hardy in USDA Zones 3–9, tolerating cold winters and hot summers with minimal care.

• pH: Neutral to slightly acidic or slightly alkaline soils (6.0–7.5) perform well.

Mountain Phlox is naturally suited to alpine and rocky environments, making it perfect for slopes, erosion control, and low-maintenance garden designs.

🌱 How to Grow from Seed
Starting Mountain Phlox from seed allows you to enjoy a thriving carpet of color in your garden year after year:

1. Timing: Sow indoors 8–10 weeks before the last frost or directly outdoors in early spring.

2. Sowing: Lightly press seeds into a fine, well-draining seed mix; do not cover, they need light to germinate.

3. Germination: Maintain a temperature of 65–70°F (18–21°C) and keep the soil lightly moist. Germination usually occurs within 14–28 days.

4. Transplanting: Once seedlings develop two true leaves, transplant outdoors, spacing 6–12 inches apart to allow the mat to spread.

5. Maintenance: Once established, Mountain Phlox is low-maintenance. Mulching lightly can retain moisture, and deadheading spent flowers can encourage additional bloom.

💧 Care & Maintenance
Mountain Phlox is an exceptionally hardy and low-maintenance plant. Once established, it thrives with minimal watering and care. Light pruning after flowering helps maintain its shape and prevents legginess. Dividing mature mats every few years encourages healthy growth and rejuvenates flowering. Avoid overwatering, especially in winter, to prevent root rot.

🦋 Pollinator & Ecological Benefits
Creeping Phlox is a magnet for early-season pollinators. Bees, butterflies, and even hummingbirds are drawn to its vibrant flowers. By planting Mountain Phlox, you are not only creating visual impact but also supporting local ecosystems and pollinator populations. Its dense growth also provides shelter for small beneficial insects.

🌸 Garden & Design Uses

• Rock Gardens: Forms a natural, colorful carpet among stones and boulders.

• Borders & Edges: Perfect low-growing accent along pathways, walkways, and garden beds.

• Ground Cover: Fills gaps and slopes with evergreen foliage and spring blooms.

• Containers & Raised Beds: Ideal for compact, decorative plantings in outdoor pots.

• Erosion Control: Dense mats stabilize soil on slopes and hillsides.
