Albuca spiralis L.f.
Frizzle Sizzle albuca
Instantly recognisable by its leaves that coil into a tight corkscrew spiral, which earned it the cultivar name "Frizzle Sizzle". Compact bulbous plant from the Western Cape. Produces fragrant, nodding yellow-green flowers in spring. Enters summer dormancy. Extremely popular in succulent collections worldwide.

Origin & Habitat
Morphology
Filiform or linear, 10–20 cm, bright green, spontaneously coiling into tight helices of 1–3 full turns; the degree of spiralling increases with intense sun exposure.
ecoTunicated bulb 2–5 cm in diameter, buried; the flowering scape is erect, 20–40 cm, and emerges in spring before dormancy.
ecoNodding, yellow-green with darker-toned keels on outer petals; fragrant; gathered in a loose raceme of 4–10 flowers in spring.
ecoContractile roots capable of pulling the bulb to greater depth in sandy soils; moderately developed root system.

Propagation Strategy
- 1 Collect seeds after flowers wither in spring.
- 2 Sow in autumn in sandy substrate with perlite at 15–18 °C.
- 3 Keep slightly moist until germination (3–5 weeks).
- 4 Respect the summer dormancy in the first year without watering.
- 1 Separate bulblets from the mother bulb at the end of summer dormancy (August–September).
- 2 Plant in sandy substrate with the apex at soil level.
- 3 Begin moderate watering and place in direct sun.
- 4 Bulblets will produce spiral leaves in the first season.
Maximum direct sun exposure during the active season to maximise leaf spiralling.
Watering during summer dormancy, which rots the bulb within weeks.
Every 3 years at the end of summer, before resuming autumn watering
Low-nitrogen liquid fertilizer (cactus type), diluted to half strength, once a month from October to March
Uses & Applications
Precautions / Toxicity
No known toxicity to humans; keep away from pets as a precaution.

"The leaf spiral of A. spiralis is not a fixed trait: in low-light conditions leaves grow straighter. Collectors use this induced photomorphism to obtain tighter spirals by placing the plant in intense direct sun during the growing season."
