hi all I totally cover my raised bulb beds with the South African composite Arctotis. I plant each colour, pink, red and tangerine, en masse. This hides all dying leaves but they don't grow fast enough when planted to hide the leaves from Narcissus fly. I plant them in April and by June there is no soil to be seen. Right now there is a sea of colour hovering over each bed. If you would like to see the effect email me and I'll send you some photos. Mark N Ireland
