HI, another idea might be to join the Hardy Plant Society / Cottage Garden Society as they lots of info plant/gardening info throughout the year put together by members. They also have an annual seed swap which produces a diverse range of seeds to choose from. It's brilliant, as well as being part of a group of like minded people. I'm hooked, having grown many plants I had never heard of or seen before, Dierama, Tulbaghia, Adenophora, species Clematis etc, and others such as different Eryngium, Asters, Lavender, Agapanthus. There are veg as well , although the swap is mostly annuals/perennials/shrubs/trees, some very unusual. Some of the seed might take 2-4 years to come to flower (such as Agapanthus) but it is often well worth the wait. I sowed some seed of Cornus Capitata about 10 or so years ago and this year they produced their first flowers, followed by strawberry like fruits. Magic! It's a great eco friendly and cost effective way of producing plants, and it's also great to curl up in the armchair with the list and the laptop checking out plant information online.
Visit their websites and maybe give it a go? The next seed swap submissions will be around August/September.
