Cloudy Day Sedum

Sedum 'Cloudy Day'

succulent

Cloudy Day Sedum is a compact, low-growing succulent with distinctive gray-blue foliage that deepens to purple-burgundy tones during cooler months or stress conditions. This hybrid sedum forms dense mounds and produces delicate pink or white flowers in late summer to fall. It's an excellent choice for rock gardens, containers, and xeriscape landscaping due to its extreme drought tolerance and minimal care requirements.

Growth Stages

1

Establishment

2-4 weeks

Young rosettes are establishing roots and beginning to form the characteristic compact mound

Water lightly every 7-10 days for first 2-3 weeks to encourage root development; then taper off. Ensure excellent drainage.

2

Vegetative Growth

Spring through mid-summer (12+ weeks)

Plant expands horizontally, forming dense cushions of gray-blue foliage; new leaves continuously emerge from rosette centers

Minimal watering; only during extended drought or if in containers. Remove any dead or diseased leaves. No fertilizer needed.

3

Flowering

Late August through October (4-8 weeks)

Flower buds appear at stem tips; delicate pink or white star-shaped flowers bloom in clusters above the foliage

No special care needed; do not deadhead unless you want to redirect energy to foliage. Flowers attract pollinators.

4

Winter Dormancy

November through February (12-14 weeks)

Foliage deepens to burgundy or purple tones; growth slows dramatically; leaves may appear slightly stressed or withered

Reduce or eliminate watering; excellent drainage prevents rot. No fertilizer. Plant is hardy and requires no protection in zones 3+.

5

Spring Renewal

March through April (4-6 weeks)

New growth emerges from the center; foliage gradually returns to gray-blue tones as temperatures warm

Begin light watering only if conditions are exceptionally dry. Gradually increase watering as growth accelerates.

Companion Planting

Plan your garden →

Plant with:

Sempervivum (Hens and Chicks) Echeveria Delosperma (Ice Plant) Penstemon Lavender Catmint Russian Sage Ornamental grasses (Festuca, Stipa)

Avoid planting near:

Water-loving plants (hostas, ferns, primrose) Heavy feeders that require frequent irrigation Plants requiring rich, organic soil Shade-dominant perennials

Common Pests

  • Prevent through excellent drainage and reduced watering; repot in fresh dry soil if affected; improve air circulation

  • Isolate affected plants; spray with insecticidal soap or neem oil; wipe leaves with rubbing alcohol on cotton swab

  • Spray with strong water stream; apply insecticidal soap or horticultural oil; rarely a serious problem on sedums

  • Increase humidity slightly; spray with insecticidal soap or neem oil; remove heavily infested leaves

Uses

🏠

Drought-Tolerant Landscaping

Household

Cloudy Day Sedum is ideal for xeriscaping, rock gardens, alpine troughs, and container arrangements where water conservation is prioritized. Its minimal maintenance needs and extreme hardiness make it perfect for busy gardeners or water-restricted regions. [source]

🦋

Pollinator Support

Wildlife

The late-season pink and white flowers provide valuable nectar and pollen for bees, butterflies, and other pollinators when other food sources are scarce in fall. [source]

🎨

Living Walls & Vertical Gardens

Craft

The shallow root system and low sprawling form make Cloudy Day Sedum excellent for living walls, green roofs, and vertical succulent arrangements. [source]

🏠

Container & Indoor Gardening

Household

Thrives in shallow pots and troughs indoors or outdoors; provides colorful foliage year-round with minimal care and no special equipment needed. [source]

💊

Mild Skin-Soothing Properties

Medicinal

Like many sedums, Cloudy Day contains compounds with potential skin-soothing benefits when used in traditional preparations, though it is primarily grown as ornamental. [source]

Harvest Tips

Not harvested for crop; flowers are ornamental and best left on plant. For propagation, gently detach individual leaves in spring/summer and lay on dry soil; new rosettes form in 2-4 weeks. Stems can be cut and propagated similarly.

Fun Facts

  • 🌱 Cloudy Day Sedum's color-changing foliage is a stress response triggered by cold temperatures and reduced water—the purple pigmentation (anthocyanins) actually protects leaves from UV damage and cold injury, making the color shift a sign of hardiness.
  • 🌱 Sedums can propagate from a single fallen leaf; a tiny rosette will form at the leaf base within weeks, making this an incredibly efficient and nearly cost-free way to multiply your collection.
  • 🌱 This sedum is hardy to USDA zone 3, making it one of the toughest sedums available and suitable for gardeners in cold climates where many succulents fail—it can survive temperatures below -40°F.
