x-Rudbeckia fulgida var. sullivantii 'Goldsturm'
The large, simple, yellow daisy flowers of Rudbeckia fulgida 'Goldsturm' are a must have favourite in the late summer border.
Its wide, open rays are a bright, sunny yellow with a prominent black eye at the centre and they bloom from mid summer right up until plants are checked by the first frosts in the autumn. Herbaceous perennials, plants form clumps with narrow, toothed mid-green leaves and their upright sturdy stems should stand tall unheeded and not need staking. They are also neat plants which don't spread and overwhelm neighbouring plants in a border, meaning clumps don't need splitting as often as some.
Lift and divide congested clumps every few years in the spring. Plants will thrive in a sunny spot, although they will cope with some shade, and a reasonably fertile soil that is moist but well drained. Remove fading flowers often to promote a continuous supply of blooms and mulch plants in the autumn and after dividing with garden compost or well rotted manure. Rudbeckia look wonderful dotted through borders in bold drifts and use them to extend the season in the garden as most other flowers tire or grow them as part of a late summer display with other long flowering perennials such as purple asters and perovskia or intermingling with verbena bonariensis.
They also look lovely with tall, flowering grasses like miscanthus and stipa. Rudbeckia are also valued wildlife plants with bees and other pollinators buzzing around the cheery blooms all summer. Leave the last few flowers of the season where they are rather than cutting down plants for the winter and birds will flock to peck at their seedheads
