Jim, I finally flowered N. laticoma after 10-11 years from seed in 2007, just one bulb out of several. I would echo exactly what Alberto said as to culture, except for "regularly flowering". In Los Angeles my bulbs grow in half day full sun and still have some green leaves even now; they are protected from rain all winter. The flowers are amazing and fortunately it is, in this instance at least, self-fertile (perhaps even autogamous or self-fertilizing). Dylan
