Crimson King is a striking evergreen succulent cultivar with rosette-forming leaves that display deep crimson to burgundy coloring, especially in cool seasons. This hardy, low-maintenance perennial is prized for its ornamental foliage and forms dense mats of "hen" plants surrounded by smaller "chick" offsets. It thrives in rock gardens, containers, and alpine settings with minimal care.

Growing Conditions

☀️

Sun: Full sun, 6+ hours daily (more sun intensifies crimson color)

💧

Water: Low water needs; water moderately during growing season (spring/early summer), reduce in fall, nearly dry in winter. Allow soil to dry completely between waterings. Overwatering is the primary cause of failure.

📏

Spacing: 6-12 inches apart (rosettes spread 3-6 inches; allow room for offset production) inches

📅

Days to maturity: Not applicable; this is a perennial. Flowering occurs in 3-4 years when mature.

🌱

Planting depth: Plant rosettes at soil level; do not bury the crown. Offsets can be pressed lightly into soil surface.

Soil

Type: Very well-draining, gritty soil (sandy or rocky loam)

pH: 6.0-7.5

Amendments:

Perlite or pumice (30-40% of mix) Coarse sand Gravel or small stones Avoid peat moss or heavy organics

Growth Stages

Establishment

2-4 weeks

Young rosettes are planted or offsets begin rooting. Foliage is present but may not show full crimson coloration.

Keep soil barely moist for 2-3 weeks until roots establish. Provide bright light. Protect from excessive moisture and heavy rain.

Vegetative Growth

Spring through early summer (3-4 months)

Rosettes expand and deepen in color, especially in cool temperatures and full sun. Offsets (chicks) begin forming around the base of the mother plant (hen).

Water sparingly; allow drying between waterings. Ensure excellent drainage. Increase sun exposure for deeper color. No fertilizer needed.

Maturation

Year 2-3 onward

Rosettes reach full size (3-6 inches diameter), displaying intense crimson coloration, especially in cool fall/winter or when stressed slightly by drought.

Continue minimal watering. Reduce watering frequency in fall and winter. Rosettes that have flowered will die after blooming; remove spent plants.

Flowering

Spring (4-6 weeks blooming)

In spring of their 4th-5th year, mature rosettes produce tall inflorescences with star-shaped pink, magenta, or red flowers clustered at the top.

Flowering is optional; you can remove flower buds if you prefer to keep plants compact. The flowering rosette (hen) will die after blooming; remove it and let offsets take over.

Offset Production & Division

Ongoing, spring through summer

Hen rosettes continuously produce chick offsets throughout the growing season. Clumps become denser and can be divided for propagation.

Allow offsets to root naturally on the mother plant, or gently detach rooted offsets and replant. Division refreshes older clumps.

Companion Planting

Plan your garden →

Plant with:

Sedum (various species) Stonecrop Echeveria Aeonium Alpine phlox Creeping thyme Dwarf conifers Ornamental grasses (small varieties) Saxifrage

Avoid planting near:

Water-loving plants (hostas, ferns, astilbe) High-moisture plants (hydrangea, ligularia) Plants requiring frequent deep watering Areas with poor drainage or standing water

Common Pests

Spray with water to dislodge; improve air circulation. Use neem oil if severe; typically not a major issue outdoors.
Remove with rubbing alcohol on a cotton swab. Improve drainage and reduce humidity. Isolate infested plants.
Prevent with well-draining soil and minimal watering. Do not overwater. If affected, repot in fresh, dry soil; discard rotted portions.
Spray with water or insecticidal soap. Usually minor; rarely requires treatment in outdoor settings.

Uses

🌿

Rock Garden & Alpine Display

Ornamental

The intense crimson coloration makes Crimson King a standout specimen in rock gardens, alpine troughs, and xeriscape designs. Its compact rosette form provides year-round visual interest and winter color when many plants fade. [source]

🏠

Container & Arrangement

Household

Perfect for container gardens, living wreaths, and succulent arrangements due to its compact size and striking color. Use in shallow pots, fairy gardens, and as part of mixed succulent compositions. [source]

🏠

Green Roof & Living Wall Installation

Household

Extremely hardy sempervivums like Crimson King are ideal for living roofs and vertical succulent walls where low maintenance and drought tolerance are essential. Their shallow root systems and lightweight structure suit these installations. [source]

💊

Traditional Folk Medicine

Medicinal

Hens and Chicks have been used in traditional herbalism for minor skin irritations and wounds, though evidence is limited. The gel-like sap was historically applied topically for its presumed soothing properties. [source]

🦋

Pollinator Support

Wildlife

When flowering, the star-shaped blooms attract bees and other pollinators, providing a late-season nectar source in alpine and rock garden settings. [source]

Harvest Tips

Not harvested for produce. For propagation: Detach rooted offsets (chicks) in spring or summer by gently twisting or cutting from the mother plant. Allow cut surfaces to air-dry for 1-2 days before planting. Mature rosettes can be divided every 3-4 years to refresh the clump.

Fun Facts

🌱 The common name 'Hens and Chicks' refers to the mother rosette (hen) and the smaller offsets clustered around it (chicks); this growth pattern is unique among succulents.
🌱 Sempervivum tectorum translates to 'live forever on the roof'—historically, these plants were planted on thatched roofs in Europe for both decoration and the folklore belief that they would protect the home from fire and lightning.
🌱 Crimson King's dramatic color intensifies in cold temperatures and under stress (drought, bright light), making winter the showiest season in cool climates.
