About Little One Temple Bells

Smithiantha 'Little One' · also called Little One Temple Bells, Temple Bells · houseplant

A compact Gesneriad hybrid prized for its velvety, red-flushed leaves edged in green and nodding yellow-orange tubular flowers. Grows from rhizomes and goes dormant in winter. An ideal size for windowsills and small containers, it rewards warm, bright conditions with a long summer-to-autumn flowering display.

Mature size: 20–30 cm tall; 20–30 cm spread

Indoor size vs how big it gets in the wild

Little One Temple Bells is a naturally small plant — it stays shelf- and desk-sized for its whole life, so it never becomes a space problem. Indoors and in a pot, expect 20–30 cm tall. In the ground with no restriction it is a completely different plant — 20–30 cm spread — which is why the pot, the light and the pruning matter so much for the size you actually end up with.

It grows mostly by adding leaves, offsets or a slightly wider rosette rather than gaining height — the footprint barely changes year to year.

Growth rate and years to mature

Little One 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: feed fortnightly during active growth (spring to early autumn) with a half-strength balanced liquid fertiliser. stop feeding once leaves begin to yellow in autumn; do not feed during winter dormancy.
