About Temple Bells

Smithiantha cinnabarina · also called Temple Bells, Cinnabarina Temple Bells · houseplant

A rhizomatous gesneriad from Mexican cloud forests bearing scarlet, tubular bell flowers on velvety stems from late summer into autumn. It enters a dry winter dormancy, dying back to scaly rhizomes, then resurges in spring. Grow it in bright, filtered light with high humidity and a peat-perlite mix — treat it like a warm, moisture-loving African violet.

Preferred mix: Peat-based, well-aerated mix

Watch for — Rhizome rot: Overwatering or cold, waterlogged soil during or after dormancy causes scaly rhizomes to rot. Ensure excellent drainage and reduce watering sharply as foliage dies back.

Reusing tired, compacted old compost or skipping the perlite. A free-draining mix in a pot with a hole solves most "why is it struggling" cases for temple bells.

pH — does it matter for temple bells?

Temple Bells is not fussy about pH — a slightly acidic to neutral mix (around pH 6.0-7.0), which a standard peat-free compost provides, is perfectly fine. No testing needed.

If you want to check or adjust it, the soil pH guide walks through testing and the safe ways to nudge a mix more acidic or more alkaline.

DIY mix vs a bagged one

A decent bagged houseplant compost works for temple bells as long as you mix in perlite for air. The simple DIY ratio above is cheap and more reliable than a budget bag alone.

Drainage and the pot

A pot with a drainage hole and a saucer you empty after watering is all temple bells needs — the free-draining mix does the rest.

Refresh temple bells's mix every 18-24 months; even good compost slumps and compacts, and fresh, airy mix is often the simplest fix for a tired plant. When the time comes, our repotting guide for temple bells covers the timing and technique step by step.
