well Dach, that just proves how good exercise is for you, I've never exercised in my life and don't intend to start now.
Dove has just done as much excersise as is needed in a day😀
That's a Begonia.
The small curly ones on the left will grow into plants as well, they are all seeds, just some bigger than others I always collect these seeds, grow them every year. and have given several away on the seed swap.
Make sure you leave them on the plant until they go brown, those look a bit green.
Have you tested your soil, if you are trying to grow anything from the Brassica family they will not grow for you in acid soil, I have to lime mine in the autumn.
Try Runner beans, easiest thing and seem tolerant to any soil, mine are fantastic in the acid soil. Others grow them well in alkaline.
The secret is to find out what your plants need and act accordingly. There are some very good books, but I always use this book, may be old fashioned but what's changed? 🙂
Keep them cool then sow around March, kitchen worktop of greenhouse, they need no special treatment, they germinate easily.
I bought this one, bit more expensive but I think it's worth it, I used it brown side up choice is yours.
Linaria purpurea Purple Toadflax
Congrats on first frog, don't count on him eating any slugs though, I have lots of frogs and toads and all my plants are chewed, 😀
Spray your white vinigar on a worm and see what happens😱
I don't know names of any particular ones, but I do know that they mostly have a short flowering season, so you will have lots of green for most of the year, you could think about other plants on the same trellis flowering at different times so that you will have flowers all year round. .
