Among the most popular for gardeners and bees are the varieties 'Goldsturm' and 'Black-eyed Susan'.
They have lovely dark centres, but if you want something different, 'Black-eyed Susan 'Prairie Sun'' is also attractive for pollinators and the centre is an interesting shade of pale green.
There are varieties with bi-coloured florets too, and beautiful Rudbeckia with rich copper petals.
Rudbeckia look wonderful planted in bold drifts if you have the space. They are simply gorgeous next to blues and purples, but I have also seen them close to grasses and it provided an interesting textural contrast.
In late summer to autumn (from around August through to October) when they are in flower, they brighten up the centre of the flower border, and provide food for bees, butterflies, hover flies and various beetles.
Grow Rudbeckia in full sun or a little dappled shade in well drained but fertile soil.
Grow from seed sown in spring under cover.
Divide perennial varieties every few years.
