What plants will attract beneficial insects to my allotment garden?
I'm planting Marigolds and Nasturtiums and have heard that the Poaced Egg plant is good for attracting hoverflies. Anything else I should be thinking of?
oops - that should have been Poached Egg plant. I'm growing vegetables - tomatoes, corn, courgettes, herbs, onions, the usual stuff - in an allotment in North London.
