Scarlets Cut Flower Patch 2022/23/24

I have an eryngium row, I am running out of space and I'm hoping they don't cast too much shadow on my old GH. Thinking that early on in the season they don't flower. Very good growth I think from an early sowing this year?

The foliage on that sea holly stays very close to the ground, it's only the flower stalks which are tall but they're also very thin so don't cast much shade. The colour of the stems on mine right now is fantastic, like a metallic blue/purple.
