I had them in pots, 5x5x6 inches deep and placed them, with most of my other bulbs, in an above ground stepped platform that was closed from the outside. It was also under deciduous trees that provided shade in the summer. I used ordinary potting soil mixed with sand and pearlite. They thrived, returning every year and blooming each spring. Since moving to Spain I have continued to grow them with little trouble, having had several flower for me last year. Many were bulbs that I brought with me, most, which have yet to flower, were grown from seed that spent three to four years in refrigeration. I had mostly good germination and regrowth from those I planted last year. I have been having very good germination from most of those I planted this year as well. My climate here is very much like the Central Valley of California. Hot dry summers and cool moist winters. Despite being inland and at a higher elevation we do not get as cold as the Sacramento Valley, more like the banana belt in the foothills above the valley. The key issue I have found is keeping the bulbs cool during dormancy. What losses I had since moving here was in pots that were not kept in deep shade over the summer. This was complicated as we were remodeling the house we bought and keeping things safe from the contractors sometimes took precedence over providing ideal summer storage conditions for my dormant bulbs.
