Too late to sow flower seed

Would it be too late to sow flower seed to flower for this year and also veg sweet corn and beans in pots etc.

I usually sow in trays /pots rather than straight in the ground.as we have better luck this way .

My carrots I sow in July to beat the fly


I did sow some earlier but germination wasn't too good.

 

Same problem here, PS. Now the soil's warm and we've had some rain, I'm going to try direct-sowing sweetcorn and beans and re-sowing carrots. We have quite a long growing season, so might get something before autumn

 

I sowed beetroot, kale, psb, swede and winter cabbage yesterday. Loads of lettuce and a few endive for salad a couple of days before.
