Growth Stages

Establishment

2-4 weeks

Young plant develops root system and establishes growth pattern

Water sparingly after planting. Avoid fertilizing for first 6 months. Place in bright location.

Vegetative Growth

3-8 months

Plant produces new leaves and elongates stems; foliage is silvery-gray and coin-shaped

Provide full sun for compact, attractive form. Water moderately during growing season (spring-summer). Pinch back leggy growth to encourage branching.

Pre-flowering

1-2 months

Leaf growth slows; plant accumulates energy for flowering

Reduce watering slightly. Provide cool winter period (50-60°F) to trigger flowering. Maintain bright light.

Flowering

3-4 weeks

Plant produces clusters of small, fragrant white or pale pink star-shaped flowers

Do not overwater during flowering. Flowers typically appear in late winter (January-March). Continue bright light.

Dormancy/Maintenance

2-3 months

Plant rests after flowering; minimal growth occurs

Water very sparingly (once per month or less). Maintain cool conditions if possible. Resume normal watering in spring.

Fun Facts

🌱 The common name 'Silver Dollar Tree' refers to the coin-like, silvery-gray leaves that resemble silver dollars; in South Africa it is sometimes called 'Money Tree' for the same reason.
🌱 Crassula arborescens can live for 40+ years with proper care, making it a potentially lifetime companion plant that can be passed down through generations.
🌱 The plant's thick, waxy leaves store water, allowing it to survive extended periods without rainfall—a survival strategy from its native semi-arid South African habitat.
