Crassula Susannae

Morphological Characteristics

Crassula susannae is a compact and rare succulent known for its stacked, rounded leaves and geometric symmetry. The plant grows in tight, columnar clusters, with thick, pale green leaves that overlap like tiles or shingles.

Its unusual architectural form gives it a sculptural appearance that’s appealing in minimalist or modern succulent arrangements. The surface of the leaves is matte and may develop a slight pink blush in cooler temperatures or with stress.

Mature plants can reach 5–10 cm (2–4 inches) in height and form dense clumps over time. In autumn or early winter, it produces small, star-shaped white to pale pink flowers on short stems that emerge between the leaf clusters.

Growth Habits

Crassula susannae is a slow-growing, clumping succulent that stays compact and tidy. It propagates naturally by offsetting, forming a low mound of repeating rosettes. Its slow rate makes it ideal for bonsai-style arrangements or decorative pots where controlled growth is desired.

Best suited for indoor containers or sheltered outdoor spaces with bright light and good airflow.

Maintenance Points

• Lighting: Prefers bright, indirect sunlight or morning sun. Too much direct sun can cause leaf burn.

• Watering: Water deeply but only when the soil is fully dry. Avoid overwatering, especially in cool weather.

• Soil: Requires fast-draining cactus or succulent soil. Add pumice or perlite for extra drainage.

• Temperature: Ideal range is 16–25°C (60–77°F). Protect from frost. Not cold-hardy.

• Fertilization: Feed with a diluted succulent fertilizer once per month during the growing season.

• Handling: Easy to handle, but avoid excessive moisture at the base to prevent rot.

Display & Use

Crassula susannae is best showcased in:

• Shallow ceramic dishes or minimalist succulent bowls

• Rock gardens and bonsai-themed compositions

• Window sills or shelves with controlled lighting

• Mixed arrangements with other compact, stacking succulents like Crassula ‘Tom Thumb’ or Echeveria minima
