Closed Bell Terrarium – Bulbophyllum auratum (orchid) & Solanum evolvulifolium
Glass size: ±15 × 21 cm
This closed bell terrarium pairs the sculptural presence of Bulbophyllum auratum with the fine, trailing detail of Solanum evolvulifolium. The orchid anchors the composition with its bold, architectural growth, while the solanum weaves gently through the landscape, softening the scene and adding movement. Together they thrive in the stable, humid environment created by the bell, forming a miniature forest edge that feels both wild and carefully composed, a slow-evolving ecosystem designed to be admired up close.
Why I love this one
This terrarium feels like a tiny forest edge frozen in time. The strong structure of Bulbophyllum auratum contrasts beautifully with the delicate, creeping habit of Solanum evolvulifolium, creating depth and flow within the glass. It’s one of those pieces that keeps revealing new details as it matures, subtle growth, shifting textures, and a sense of quiet balance that makes it incredibly rewarding to live with.
Light
Bright indirect light
Ideal for a well-lit room, office, or shelf near a window
Avoid direct sun, magnified heat inside the glass can damage both plants
Temperature

Watering
This terrarium includes a dedicated drainage layer of stones / clay balls
Water must never rise above this drainage layer
Only top up once the drainage layer is dry
Use reverse osmosis or distilled water only
A small amount goes a long way — this is a self-contained system
Condensation
Light condensation on the glass is normal and healthy
Heavy, constant condensation means too much water or too much heat
If needed, briefly lift the bell for a few minutes to rebalance
Air refresh
Refresh the air every 2–4 weeks by lifting the bell for 5–10 minutes
This helps prevent stagnation and supports long-term plant health
Care level
Low, once established This terrarium is designed to settle into a stable rhythm. Resist the urge to interfere, minimal input keeps the internal balance intact.
