if at first you don't succeed

Try again. And keep on trying. Eventually something will grow.

Here in this tub are 2 cauliflower seedlings on the left; 2 broccoli seedlings on the right.
One of my favourite winter side dishes is cauli and broccoli baked in cheese sauce. Preferably served alongside roast beef.

 Another cauliflower. I have 4 altogether.

Here is another broccoli. The feathery green in the background is carrots.

 In this tub are 4 cabbage seedlings. I really love my green vegetables. See that tiny seedling on the left in the middle?

Here it is again. It's a mini cabbage. Full sized the head is firmly packed and about 4 inches across.
Much more economical for a single (or two) person household.
I have mini cauliflowers too, they're about the same size as this tiny cabbage.

Once this lot is harvested and shared around with my family, the tubs will be dug over, have compost and a little manure added, then they'll sit idle for a couple of months before planting again with summer produce.
I'm thinking of trying cucumbers.......
