Albuca viridiflora Jacq.
Green-flowered albuca
Unusual for its fully green flowers (viridiflora = green-flowered). Has broad strap-like leaves. Prefers shadier, moister habitats than most albucas. The tall flower spike bears many small green flowers. Its wider distribution towards Zimbabwe and Mozambique distinguishes it from strictly Cape albucas.

Origin & Habitat
Morphology
Broad strap-shaped, 2–5 cm wide and 30–60 cm long, deep glossy green; broader than in most albucas, reflecting their semi-shade habitat.
ecoTunicated bulb 4–7 cm in diameter, subterranean; erect, robust flowering scape, 60–120 cm.
ecoSmall nodding flowers entirely green, with all six tepals the same uniform green colour; arranged in a dense raceme of 20–50 flowers; spring flowering.
ecoWell-developed fibrous root system, adapted to moist, organically rich soils of riverbanks and understorey.

Propagation Strategy
- 1 Extract the mother bulb in winter when leaves enter rest.
- 2 Carefully separate lateral bulblets with a clean knife.
- 3 Treat cuts with activated charcoal or sulphur powder.
- 4 Plant in moist organic substrate and keep in partial shade.
- 1 Sow fresh seeds in moist organic substrate at 20–22 °C.
- 2 Keep in partial shade with constant moisture.
- 3 Seedlings need 3–5 years to reach flowering size.
- 4 Do not allow the substrate to dry out at any point in the juvenile cycle.
Grow in partial shade; unlike most albucas, it does not need full sun.
Placing in intense full sun, which scorches the broad leaves.
Every 2–3 years in spring when roots fill the pot
Balanced liquid fertilizer (NPK 10-10-10), monthly from spring to summer

"The entirely green flowers of A. viridiflora are unusual in the plant kingdom; this cryptic colouration is believed to be an adaptation to attract specific pollinators in the shaded riparian understorey environment where showy colours are less effective."
