Hello Nicholas, Welcome to the PBS, you will find a lot of inspiration and information here! Why hesitate with seeds from the Southern Hemisphere? Amaryllid seed which has a short life span only should always be sown immediately on receipt. It is no good idea to store it until a presumably good moment in our northern hemisphere will come. Seed of southern hemisphere origin, if sown immediately will germinate when it wants to, most Amaryllid seed will germinate very quickly if the seed is good. The seedling will not go (fully) dormant during the first year in most species so the time of sowing does not matter anyway. Also you have good conditions, maybe too warm for some of them but this will show. After its first year, sometimes even later the seedling will automatically adapt to the seasons where it is actually grown and will then be either winter or summer growing. If you want to sow winter growers at the wrong time of the year it is important to keep the seed pot as cool as possible especially if the seed germinates. Iridaceae seed, Araceae seed and even some Amaryllid seed have a longer life span than we often think and if there is enough seed it is always a good idea to keep some seed for a later sowing if the first one fails. Also it is important to know that a lof of species have seed dormancy that need specific conditions to be broken, sometines it takes more than one or two years from sowing to germination, do not throw such pots away too early. All the best and good luck Uli
