Gold Moss

Sedum acre

flower

Gold Moss is a low-growing, mat-forming succulent groundcover with tiny, needle-like golden-green foliage that turns brilliant yellow to orange in cooler temperatures and bright sunlight. It produces delicate star-shaped yellow flowers in late spring to early summer and is extremely hardy and drought-tolerant once established.

Growing Conditions

☀️
Sun: Full sun, 6-8 hours daily; intense sun intensifies golden-yellow coloring and prevents legginess
💧
Water: Low water needs once established; water sparingly during growing season, only when soil is completely dry. Drought-tolerant. Reduce watering in winter to prevent root rot. Overwatering is the primary cause of failure.
📏
Spacing: 6-12 inches apart for mat-forming coverage inches
📅
Days to maturity: Blooms appear 60-90 days after planting; groundcover fills in 3-4 months
🌱
Planting depth: Plant at soil level; do not bury; press gently into well-draining soil

Soil

Type: Well-draining sandy or gritty soil; tolerates poor, rocky soil
pH: 6.0-7.5
Amendments:
Coarse sand or perlite for drainage Gravel or small stones Avoid heavy amendments—lean soil encourages color and hardiness

Growth Stages

1

Establishment

2-4 weeks

Tiny rosettes begin rooting and spreading horizontally; foliage is compact and tight

Water lightly to establish; ensure perfect drainage to prevent rot. Minimal care needed.

2

Vegetative Growth

6-8 weeks

Dense mat of needle-like foliage expands outward; coloring shifts from green-gold to deeper golden-yellow with sun exposure

Allow soil to dry completely between waterings. Full sun exposure intensifies color. No fertilizer needed.

3

Flowering

4-6 weeks (late spring to early summer)

Delicate yellow star-shaped flowers appear on short inflorescences above the mat; blooms cluster densely

Continue dry conditions; deadheading is optional but can encourage longer bloom. Light watering acceptable during active growth.

4

Post-Bloom & Dormancy Preparation

6-8 weeks (late summer through fall)

Flowers fade; foliage intensifies color in fall, turning deeper orange-yellow or russet in cool temps; growth slows as temps drop

Reduce watering significantly; allow dormancy. Cold exposure enhances fall color. Minimal maintenance required.

5

Winter Dormancy

3-4 months

Plant enters dormancy; growth nearly stops; foliage retains rich golden-orange hues in cold climates

Withhold water; no feeding. Extremely cold-hardy—survives well below -30°F. Excellent winter interest.

Companion Planting

Plan your garden →

Plant with:

Sempervivum (hens and chicks) Other Sedum varieties (Dragon's Blood, October Daphne) Creeping Thyme Delosperma (ice plants) Pulsatilla (pasque flower) Dianthus Armeria (sea pink)

Avoid planting near:

Shade-preferring hostas Moisture-loving ferns Plants requiring rich, amended soil Aggressive spreading plants that may smother it

Common Pests

  • and

    Rare due to succulent foliage; remove by hand if spotted. Copper tape or diatomaceous earth if severe.

  • Increase air circulation; rarely serious. Spray with water or mild insecticidal soap if necessary.

  • Not a pest but a cultural issue—ensure perfect drainage and allow soil to dry completely between waterings. Remove affected plants and replant in fresh, dry soil.

  • Spray with strong water stream or insecticidal soap; rare on healthy plants.

Uses

🏠

Groundcover and rock garden focal point

Household

Gold Moss forms dense, attractive mats ideal for rock gardens, alpine troughs, and between stepping stones. Its golden-yellow foliage provides year-round color contrast and requires minimal maintenance once established. [source]

🏠

Living roof and erosion control

Household

Extremely drought-tolerant, shallow-rooted nature makes it suitable for living (green) roofs, walls, and banks where erosion control is needed without ongoing irrigation. [source]

🎨

Container and terrarium garden design

Craft

Gold Moss thrives in shallow containers, hypertufa planters, and succulent terrariums. Its compact form and vibrant color make it a top choice for mixed succulent arrangements and dish gardens. [source]

🦋

Pollinator attraction

Wildlife

The delicate yellow flowers attract bees and other small pollinating insects in late spring and early summer, supporting beneficial insect populations in xeriscapes and drought-tolerant gardens. [source]

🏠

Low-maintenance xeriscape and drought-tolerant landscaping

Household

Gold Moss is essential for water-wise gardens, requiring no supplemental watering after establishment, no fertilizer, and virtually no pruning. Perfect for semi-arid climates and sustainable landscape design. [source]

Harvest Tips

Gold Moss is ornamental; no harvest needed. Flowers can be enjoyed in situ. Foliage can be gently trimmed if it spreads beyond desired boundaries—cut or pull stems and allow to dry for propagation. Best visual impact from late spring through winter, with peak color in fall and early winter.

Fun Facts

  • 🌱 Gold Moss naturally propagates by fragmentation—tiny stem pieces falling to the ground root easily, allowing it to spread and fill gaps with minimal human intervention.
  • 🌱 The plant's color transformation is temperature-dependent: golden-yellow in warm seasons intensifies to brilliant orange-red or russet in cold temperatures, making it a living seasonal indicator in the garden.
  • 🌱 Despite its delicate appearance, Gold Moss is so hardy it survives in alpine environments and on rocky hillsides across Europe and Asia, earning it the alternative name 'Biting Stonecrop' from its peppery taste and resilience.
