Homalomena sp. 'Platinum Black' – Sculptural Dark Foliage for High-Humidity Interiors
Homalomena sp. 'Platinum Black' isn’t oversized or flashy. It’s compact, quiet, and strikingly elegant — thanks to foliage so deep green it borders on black. With consistent humidity above 75%, leaves develop a satin sheen and stay crisp-edged, reflecting just enough light to highlight their sculptural form. This species remains under 30 cm and forms a slow-spreading, self-heading clump — ideal for terrariums or plant cabinets.
Not a beginner plant: Success depends on stable warmth, high humidity, and precise watering. When those conditions are met, it rewards with dense symmetry and rare texture.
