Begonia variabilis sp. ‘Nopphitan’

Begonia variabilis sp. ‘Nopphitan’ is a rare Southeast Asian Begonia known for its elegant, patterned foliage and compact growth habit. It is typically identified by:

• Small to medium heart-shaped leaves

• Silvery or pale green surface with dark veins or mottled patterns

• Slightly textured, often matte or soft-glossy leaf finish

• Upright but delicate stems, making it suitable for terrariums and cabinet growing

This variant is admired for its subtle beauty rather than dramatic coloration, making it a favorite among collectors of miniature and species-type Begonias.

Background and Origin

• Originates from Southeast Asia, likely Thailand or adjacent regions

• Related to the Begonia variabilis complex, a group adapted to moist forest floors

• Found in shaded, humid habitats with steady warmth

• Grows naturally among leaf litter, limestone rocks, and mossy substrates

The name “Nopphitan” refers to a locality or collection reference used by Thai growers. It is not an officially described taxonomic variety, but a horticultural identification used in cultivation.

Care Tips

Light

• Prefers bright, indirect light or medium filtered light

• Too much sun washes out the patterning

• Too little light produces elongated stems and dull leaves

Watering

• Keep the soil evenly moist but never soggy

• Allow the top layer to dry slightly before rewatering

• Use soft or filtered water if possible

Humidity

• Requires moderately high humidity: 70–85 percent

• Ideal for terrariums, glass cabinets, or grow boxes

• Low humidity causes leaf curl and dryness at the edges

Temperature

• Optimal temperature range: 20–26°C (68–79°F)

• Avoid temperatures below 17°C (62°F)

• Sensitive to sudden drops in temperature

Soil

• Airy, well-draining mix

• Recommended blend: coco/peat, perlite, fine bark, a bit of sphagnum

• Avoid compact or heavy soils, which quickly lead to rhizome and root rot

Fertilization

• Light feeding every 2–3 weeks during active growth

• Use a gentle, diluted balanced fertilizer

• Avoid strong fertilizers, which can stress the roots

Additional Notes

• Very stable in terrariums but more sensitive in open-air environments

• Propagation is possible through leaf cuttings or small stem cuttings

• Keep airflow gentle but consistent to prevent fungal issues
