Rudbeckia fulgida var. deamii
black-eyed Susan
Charming, daisy-like flowers with prominent, cone-shaped, blackish-brown centres appear in abundance from August to October. This beautiful 'black-eyed Susan' is an excellent choice for the middle of a late summer border and it associates particularly well with ornamental grasses.
Rudbeckia fulgida var. deamii is a particularly free-flowering variety, that is best planted in bold drifts in a sunny or partially shady site that doesn't dry out over summer.

How to care for Rudbeckia fulgida var. deamii:
Rudbeckia thrive in full sun and well-drained soils, avoiding waterlogged conditions in winter. Improve heavy or clay-based soils by incorporating generous amounts of compost or other organic matter prior to planting.
Protect young growth from slugs and snails, as they can quickly decimate tender new foliage. Once established, Rudbeckia are generally low-maintenance, but benefit from occasional division, in late autumn or early spring, to rejuvenate congested clumps.
As the flowers emerge, provide support by installing ring stakes or placing brushwood around the base of the plants. This helps to prevent flopping, especially for taller varieties or those in more exposed gardens.
