Chrysogonum
A remarkable little genus, 5 species, 4 of which are endemic to Madagascar and 1 native to the Eastern USA! Semi-evergreen perennials, tolerating sun to part shade, producing golden-yellow daisy-like flowers in spring and summer.
As with all 'daisy-like' flowers, the disc-flowers in the centre of the flowerhead produce nectar and pollen that are attractive to insects, especially bees and flies, and pollen beetles that devour the pollen. With fewer disc-flowers than many of its relatives, it doesn't pack as much wildlife punch as some, but it is a useful resource in shade.
