I grow lots and lots of flowers alongside the veggies and fruit. each bed has a section of one end planted with flowers, and there are several beds just for flowers too. I do have the luxury of space, but it lifts the spirits to see it all so colourful, and passers by often comment at how good it looks too.
The flowers feed insects too, hoverflies, solitary bees, lace wings, all sorts of beneficial creatures, and I try to choose those that help them out. Except for dahlias... I grow them as I love them, and this year several othe r plot holder nearby also have planted some. Thye fell out of fashion for a while so it is good to see their resurgence on our site
