My experiance with these small daffodil species is that the flowers often abort if they are coverd or kept too dry in growth. Also crowded clumps seem to set a disproportionately small quantity of seed, as recently discussed with another section which Ina is growing. N triandrus is not sterile in cultivation, -I have had seeds on my plants in the past. The bulbs sold by Michael at Slack Top Alpines were seed grown and some of my plants came from him. Seed of N triandrus varieties is regularly offerd in the Alpine Garden Society seed exchange.
