Eye-catching purple, star-shaped flower clusters on foot long stems arise in late spring to early summer from a bulb-like corm. The bright green, strap-like foliage emerges in late winter and begins to go dormant just before flowering so plant among low growing perennials or groundcovers which will cover the fading Triteleia leaves.

- Culture Notes
- Triteleia laxa 'Queen Fabiola' grows best in full sun and very well-drained soil; this bulbous corm will tend to rot if the soil doesn't drain well during the winter. The plant blooms in late spring to early summer so be sure to water regularly if the dry season begins before it flowers. After flowering it goes dormant and is drought tolerant. The bulbs can be divided at any time during dormancy.
- Geek Notes
- Triteleia laxa is native to most of California and, less commonly, in southwestern Oregon from sea level to 4,600 feet (0 to 1500m). The habitat is variable from mixed evergreen forests, grasslands, and foothill woodlands to areas of chaparral. In the wild the timing of foliage dormancy depends on the weather and where a particular form grows; this is also true for the time of bloom which can be from April to July. Flower color varies considerably from lavender to purple or violet with an occasional white. This selection of Triteleia laxa was named in honor of Queen Fabiola of Belgium (1928-2014).
