Rhubarb I cut my rambling rose, of a similar size to yours right back, down to the base last spring, and it looks gorgeous this year. Mind, a climber might not respond as well...
My Teasing Georgia rose (a yellow David Austin English Rose) looks good as it fades - gets rather blousy, and paler.
I have to say I really recommend Mara des Bois strawberries - they taste divine, and, as I have happily discovered, having forgotten to net them, the birds don't eat them (some slug damage but not much). My Alexandria wild strawberries are doing really well this year too - such large berries - I don't know if it's the variety or the rain earlier in the year (probably both).
Bertha I haven't any flowers on my runners yet - just masses of growth. But great excitement - I have some teeny yellow courgettes. Little Bearleigh's vegetables are doing nicely too.
I picked all the redcurrants on the bush on Sunday - 15 1/2 oz, and made Jane Grigson's/Eliza Acton's redcurrant jelly - so much simpler than any other recipe I have tried - light covering of water in bottom of pan, melt berries (no need to destalk) with equal weight of sugar - when sugar dissolved, boil for 8 minutes, strain through a sieve, pot. It's beautiful - maybe not absolutely crystal clear, but so little work!
