Aeonium arboreumAlso known as: Tree Aeonium, Tree Houseleek, Black Rose

Aeonium is a striking succulent from the Canary Islands, forming rosettes of spoon-shaped leaves on woody stems. It can grow up to 3 feet (90 cm) tall and is unique among succulents for being winter-growing and summer-dormant. Popular varieties include the dramatic dark purple 'Zwartkop' (Black Rose).

Seasonal Care Schedule

Adjust your care routine based on the season for optimal plant health.

Watering Schedule

Season	Schedule
Spring	Every 7-10 days during active growth
Summer	Sparingly - dormant period, every 2-3 weeks
Fall	Every 7-10 days as growth resumes
Winter	Every 7-14 days - active growing season

Opposite of most succulents - grows in winter, dormant in summer. Adjust watering accordingly.

Fertilizing Schedule

Season	Schedule
Spring	Monthly with diluted balanced fertilizer
Summer	No fertilizing during dormancy
Fall	Monthly as growth resumes
Winter	Monthly during active growth

Fertilize during the growing season (fall through spring), not summer.

Pruning

Frequency: As needed for shape

Best Season: Fall or winter

Cut stems to encourage branching. Cuttings root easily. Remove dead rosettes after flowering.

Repotting

Frequency: Every 2-3 years

Best Season: Fall

Use well-draining soil. Repot at the start of the growing season (fall). May need staking when tall.

Flowering

Season
Late winter to spring on mature plants

Color
Yellow pyramid-shaped flower clusters

Monocarpic - the flowering rosette dies after blooming. Takes several years to flower.

Propagation Methods

Stem cuttings - root easily in soil
Individual rosettes with stem attached
Let cuttings dry for 2-3 days before planting

Common Problems

Dropping leaves in summer: Normal dormancy behavior
Leggy growth: Not enough light
Closed rosettes: Conserving water during dormancy - normal
Root rot: Too much water, especially in summer

Pro Tips

Remember: winter grower, summer dormant - opposite of most succulents
Dark varieties need more sun to maintain color
Protect from temperatures below 40F (4C)
Rosettes naturally close during dormancy - don't overwater
