Gold Moss
Sedum acre
flowerGold 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.

Establishment
2-4 weeksTiny rosettes begin rooting and spreading horizontally; foliage is compact and tight
Water lightly to establish; ensure perfect drainage to prevent rot. Minimal care needed.
Vegetative Growth
6-8 weeksDense 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.
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.
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.
Winter Dormancy
3-4 monthsPlant 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.

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.

Uses
Groundcover and rock garden focal point
HouseholdGold 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
HouseholdExtremely 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
CraftGold 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
WildlifeThe 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
HouseholdGold 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.
