Being new member since this year, and consequently this is my first seed exchange to which I will be contributing with 5 different species I may as well put here what motivates me to do it. First, I find it fun to collect the seeds from my plants and compared to previous years I am doing this much more 'involved', really trying to harvest as many good seeds as possible. By the way, since my seeds all are of the late maturing kind (It's early November and most of my seeds are still hanging to the plants) but I promised Stuart to send seeds, I feel I must honor this now of course. Sending the E-mail was the easy part of the job
But I also think that if I feed the seed exchange with my seeds, this will inspire other persons to do the same, in the end I think most of us want to enlarge our collections with hard to find species or at a better price than on commercial websites, and this community makes it possible.
Also, in the past I often had way too much seeds, I really do not have space & time to take care of thousands of Eucomis bulbs for instance, so rather than throwing away I may as well make somebody else happy with my seeds. And in some way it will be fun to know seedlings of my plants growing all over the world. And the cost to me is moderate, probably it will cost me 15 EURO or so to send the seeds, and twice a week half an hour of my time to collect and clean the seeds.
