Lachenalia trichophylla is a rare and distinctive winter-growing bulb native to the Western Cape of South Africa. This species is highly valued by collectors for its unusual fine, thread-like (filiform) leaves, which give the plant a delicate, grassy appearance unlike the broad leaves seen in most Lachenalia.

Growth begins in late autumn as temperatures cool. One to two narrow leaves emerge from a small subterranean bulb, followed in winter by a short flower spike bearing small tubular to bell-shaped flowers, usually in soft greenish-white to pale yellow tones. The flowers are subtle and refined, making this species more appreciated for its botanical uniqueness than bold color.

During late spring to summer, the foliage dies back completely and the bulb enters dormancy, requiring dry conditions.

Plant Details

Growth type: Winter-growing geophyte

Dormancy: Summer (fully dormant)

Origin: Western Cape, South Africa

Habit: Compact, slow growing

Best use: Pots, bulb pans, collector displays

Light / Sunlight

Full sun to partial shade

Bright light encourages compact growth and healthy flowering

In very hot climates, light afternoon shade is beneficial

Watering

Start watering when new growth appears in autumn

Water moderately during winter growth; allow soil to dry slightly between waterings

Stop watering completely in summer dormancy

Avoid excess moisture at all times to prevent bulb rot

Soil Mix

Requires excellent drainage

Recommended mix:

40–50% pumice / perlite

30–40% coarse sand or grit

10–20% light organic soil or coco peat

Shallow pots with good drainage holes are ideal

Temperature

Prefers cool winter temperatures

Can tolerate mild frost if kept dry

Summer heat is safe only when dormant and dry

Propagation

Offset bulbs (slow)

Seeds (flowering may take several years)
