Gardeners' Notes:

Positive Ursula On Jul 2, 2007, Ursula from Santiago
Chile (Zone 9b) wrote:

This lovely Iridaceae has its natural habitat at full sun is dry soils (requires little watering). The bright gold-yellow flowers have very fine brownish veins that bloom during spring and summer. They are of fast growth and bloom the first year if grown from seeds, reaching its best flower display from the second year on. Again, good drainage is a must.

Propagation from seeds: during autumn in a mix of equal parts of compost, regular garden soil and river sand. Place a layer of sharp river sand on top of this mixture, distribute the seeds and slightly cover with another layer of sand. Place the sowing pan in a cold frame or cold greenhouse. Transplant once the seedling reaches 5 cm (2"). This plant can also be propagated dividing its rhizomes.

Recommended for borders, to naturalize on a meadow, in flowerbeds, pots, containers, etc. Can be used as cut flower.
