Hoverflys:

According to this site they do:

When my coriander flowered last year it was covered in hoverflys, so i will be growing that again this year!

We grew orange flowers between our tomatoes last year to attract hoverflies.  Small  plants about eight inches high with fern like leaves with orange heads.  Like Marigolds but called something else.  Sounded like it began with an A or an E.  (I'm from Essex so it's difficult to tell!)

Can you tell that I don't really do flowers!

If flowering  Coriander works then I'd like to give that a go this year.

African marigold?

Your flowers sound like Tagetes. The smell keeps whitefly away in the greenhouse and I use one per tomato plant plus an extra one for my climing french beans which do well in the greenhouse too. 

I give hover flies the credit for me having barely any greenfly in the greenhouse at all last year. Whenever I had a small outbreak there's be the little hoverfly grubs amongst the greenfly filling their boots. Bless em.

What did you use Faz to attract them?
