I like the plant and seed society idea, and my contribution/suggestion would be to make the back garden actually into a winter garden, speak to build a greenhouse or polytunnel to extend the season and have room for hanging out and plant propagation, sanctuary for suffering Forest cafe plants, herbs etc. whatever you wish...
I will be back to realise the project (if agreed by the commitee and possibly the Settlement) in September, until then, if you want to use the garden for propagation in the meantime etc. feel wellcome. We have heaps of plant pots, compost is coming along slowly. There are seeds in the filing cabinet in the Forest garden file to be used, flowers, herbs, radish etc.
If you find any beautiful flowers getting into seed, please collect the seeds so we can propagate them.
PS: for isabelle
I found a papyrus plant and am in the process of letting it develop roots, when ready You can have it. they grow beautiful and enormous.
