About Many-Flowered Temple Bells

Smithiantha multiflora · also called Many-Flowered Temple Bells, White Temple Bells · houseplant

The tallest of the wild Smithiantha species, native to Oaxaca, Mexico, bearing dense spikes of creamy-white flowers with a pale yellow throat from summer through autumn. Velvety, heart-shaped leaves are soft green. It dies back to scaly rhizomes in winter. Grow in bright filtered light with consistently high humidity; an excellent species for collectors seeking the classic white-flowered form.

Mature size: Up to 1 m tall in flower; spread 30–40 cm

Watch for — Root rot: The tall stem demands well-draining soil; waterlogged conditions quickly rot the scaly rhizomes. Always use a pot with drainage holes and a light, porous mix.

Indoor size vs how big it gets in the wild

Many-Flowered Temple Bells grows into a room-scaled plant of roughly up to 1 m tall in flower — bigger than a tabletop plant, but not a tree. Indoors and in a pot, expect up to 1 m tall in flower. In the ground with no restriction it is a completely different plant — spread 30–40 cm — which is why the pot, the light and the pruning matter so much for the size you actually end up with.

It builds steadily in both height and spread to a medium, manageable size, filling a pot and a corner over a few years.

Growth rate and years to mature

Many-Flowered Temple Bells is a moderate grower. Realistically, expect three to six years to reach mature indoor size, gaining a steady amount each growing season. Its feeding profile backs this up: apply a balanced liquid fertiliser (or one slightly higher in potassium) at half strength every two weeks from spring through to the end of flowering. discontinue once foliage begins to die back in autumn.
