Hi Martin, Mike Mace gathered together lots of information from this list over the years and from other sources about how to grow bulbs from seed and added it to the wiki: http://pacificbulbsociety.org/pbswiki/index.php/… It's a treasure trove of information. Read over the section on Amaryllids. Seedlings can usually be grown on without a dormancy in their first year and sometimes longer. So keep them watered until they show signs of wanting to go dormant. Brunsvigia grandiflora has adjusted to growing on a different schedule for us in Northern California. It has been an exception to other South Africans Amaryllids that at least I have grown as they eventually were growing in the time frame you would expect. Here it has bloomed from November to December for me and November at the University of California Botanical Garden and another Northern California friend has one blooming right now. So it must be one of those species that responds to moisture. I made a note on the entry for it on the wiki that my plants bloomed in December in the Northern Hemisphere in our late fall-winter and weeks later on a trip to South Africa I saw it blooming in the wild in their summer.
