The plant has a rosette shape, with ovate, thick, and fleshy leaves. The front of the leaves is slightly concave, while the back is convex with an arched shape. The tips of the leaves are sharply pointed, and the leaves display a powdery green color with prominent red edges. The overall appearance gives off the signature translucent look of the Moonshadow series succulents.
Growth Environment
Prefers warm, dry, and well-lit conditions.
Highly drought-tolerant and thrives in loose, well-draining, and aerated soil.
No distinct dormancy period.
Protect from cold when temperatures drop below 5°C (41°F).
Provide shade when temperatures exceed 30°C (86°F).
Light Requirements
Echeveria 'silhouette's love sunlight.
Place them in a well-lit location.
Rotate the pot occasionally to promote fuller and more even growth.
Repotting
This succulent grows relatively quickly.
To maintain optimal growth space, it is recommended to repot and replace the soil every 1–2 years.
Watering
Water only when the soil is completely dry.
During periods of consecutive rainfall or high humidity, wait a few additional days after the soil dries before watering.
Soil
The Moonshadow series, including Shadow, has higher soil requirements.
Ordinary potting soil may not achieve the plant’s best condition, especially for balcony growers.
Use highly granular soil to ensure excellent aeration and drainage.
A mix of 70% or entirely granular soil works well.
For root health, place a thin layer of nutrient-rich soil near the roots and surround it with granular soil.
This type of soil has strong water permeability, ensuring even water absorption and allowing the plant to store as much moisture as possible in its leaves, resulting in fuller, more vibrant foliage.
Fertilization
Apply fertilizer sparingly. Avoid concentrated or raw fertilizers.
Fertilize in conjunction with watering.
Seasonal Notes
In summer, when temperatures exceed 35°C (95°F), Echeveria 'silhouette's enter dormancy and stop growing entirely.
During dormancy, water absorption is limited, and excessive watering combined with high heat and humidity can cause root rot.
Flowering and Propagation
Echeveria 'silhouette's often produce flower stalks from the leaf center. Once this happens, the central growth stops, and side shoots often sprout between the leaf layers, forming attractive clusters.
Losing the central growth point can be beneficial, as it encourages the plant to develop beautiful offsets.
With proper care, Echeveria 'silhouette's will thrive and showcase their unique beauty, creating a stunning addition to any collection.
