In the Pacific Northwest sustained dormancy is a big problem for winter
growing bulbs. Moraea in addition to many genera fail to break dormancy in
fall due to a lack of warm temperatures in summer to signal that summer has
actually come. What is recommended if you are really serious about growing
Moraea and other SA winter growers in climates that are perennially cold or
cool, is either have them in a greenhouse where summer temperatures will
actually get higher or lift the bulbs and store them indoors or somewhere
where you can keep them as warm as possible (80-90 is ideal), then plant
them or bring them outside when temperatures start to drip. Ive dealt with
this for years, its a problem but if you're dedicated you can get around it.
