Begonia 'Tiny Gem' - Welsh Grown

As the name suggests, Begonia ‘Tiny Gem’ is a petite powerhouse of foliage interest. It forms a tight, low-growing mound of rounded, iridescent leaves, often in tones of deep green, bronze, and silver, depending on light levels. This rhizomatous begonia stays compact and is perfect for terrariums, small pots, or grouped indoor plant displays where space is at a premium.

Scientific Name
Begonia ‘Tiny Gem’ (from Latin gemma, meaning “bud” or “jewel” – a fitting name for this glittering miniature variety)

A cultivated rhizomatous hybrid, likely developed from Begonia bowerae or similar species. Part of a group bred for compact growth and bold foliage, it is often found in rare plant collections and terrarium displays.

Common Name(s)
Tiny Gem Begonia, Miniature Begonia

Origin
Cultivar bred in cultivation; parent species native to tropical Central and South America

Light
Bright, indirect light is ideal. Too much sun will scorch the leaves; too little may dull its iridescence and slow growth.

Water
Water when the top 2–3cm of soil feels dry. Keep soil lightly moist but never soggy. Avoid letting water sit on the leaves or in the crown. Reduce watering in winter.

Humidity
Loves moderate to high humidity – perfect for terrariums or enclosed displays. If grown in open air, use a pebble tray or keep with other humidity-loving plants.

Soil
Use a loose, airy mix – a blend of compost, perlite, and orchid bark or leaf mould works well. Excellent drainage is essential to avoid root rot. Repot every 1–2 years in spring.

Food
Feed every 4–6 weeks in spring and summer with a diluted balanced liquid fertiliser. Do not overfeed – excess nutrients can cause leggy growth.

Temp
Ideal temperature range is 18–24°C. Protect from draughts and avoid temperatures below 15°C.

Pet-safe
Toxic if ingested – keep out of reach of pets and children.

Sprouts Top Tips
‘Tiny Gem’ thrives in shallow pots and appreciates being slightly rootbound. Rotate occasionally for even growth and remove spent leaves to keep it tidy.

Extras
Flowers are small and pale pink, often appearing in loose clusters – but the real attraction is the shimmering foliage.
