Hardiness: Not reliably hardy.
Growth: Evergreen. Active growing season fall to early winter; enters semi-dormancy in late spring. A shy bloomer in general. Main flowering season late summer to fall. In milder climates, it flowers at any time of year. Bulbs multiply rapidly.
Cultural Requirements: Bulbs generally enjoy being neglected. No particular soil requirements. Bulbs enjoy sandy, well drained and heavily mulched soil or growing medium with high organic contents. Grows well in indirect sunlight and shade. Reduce watering when growth slows down. Withhold watering up to few months to induce flowering. Feed bulbs 2 - 3 times in the spring. In severe climate, bulbs can be removed indoors or dug out and stored dry until the weather is warm enough. Excellent subject for both pot and ground cultivation. Generally pest free.
Natural Habitat: West from Curitiba to Rio Parana, southern Brazil.
Distinguishing Features: Flowers are reticulated with lilac-purple to deep cerise pink.
Leaves: mid-rib with a prominent white stripe which is dominant in F1 hybrids, successive breeding dilutes the character.
Variations/Forms: Slight variation of darker, narrower leaves and flowers of varied degree of "ruffling", sizes and pinks are observed.
Comment: Said to be self-compatible but it is also observed that some clones are self sterile. Widely cultivated throughout Asia.
