TUFA ROCK The Ultimate Butterwort (Pinguicula) grow medium. Bring your carnivorous plants back to what nature intended.
Hand-harvested in British Columbia, Canada, our premium tufa rock is a naturally formed, highly porous stone created by cold, mineral-rich flowing waters. It’s the ideal growing medium for Butterworts (Pinguicula) and a wide range of rock and alpine plants.

Provides the higher pH environment that many Pinguicula and alpine plants thrive in.
Long-Lasting & Stable
Won’t break down or compact over time like traditional mixes.
Perfect for Crevice Growing
Mimics natural limestone habitats—ideal for mounting and display-style planting.
