Eating those flowers

Thanks for your kind messages  you lovely people.  I had a snooze and feel a bit (not a lot) better. I have to tough it out as there's no point sitting around feeling sorry for myself  because it won't change a thing. Being British, a nice cup of tea soon roused me and I nipped out into the garden and planted some more Rainbow Chard and Purple Kale. At the moment I am tucking edible plants that will feed us in the colder months in between the flowers in my pretty borders but next year I plan to grow a whole load more food in my garden. I have just sown a few more runner beans so that I can extend the harvest a bit.  Yesterday I planted the tomato cutting down in the secret garden even though it hadn't been hardened off. It's really quite warm outside and the secret garden is very sheltered. I checked the tomato last night and it was looking very sorry for itself so I didn't know if it would survive the transplanting. This morning it looks amazing, all perked up and ready to grow.  Next year I am planning to put some Jerusalem artichokes into a far corner of the secret garden. The flowers will be pretty and I can eat the tubers without having to give them too much attention. I intend to grow a lot more climbing beans up the supports that I put in for my sweet peas and will plant fewer sweet peas. Just enough for a little vase full every few day. I would really appreciate some suggestions for pretty but edible plants that will grow in a UK climate.  It doesn't have to be something that can be planted  right now as this is a bit of a long term project for me.
