How to Grow

Maintenance for this compact perennial is minimal. Good air circulation is beneficial to prevent common fungal issues. To maximize the bloom period extending from July through September, deadhead spent flowers regularly. This practice encourages the plant to produce new buds rather than diverting energy into seed production.

Rudbeckia fulgida ‘City Garden’ will slowly spread by rhizomes, gradually forming pleasant clumps over time. In early spring, cut back the previous season’s dead foliage near the ground to allow fresh growth to emerge cleanly. This species generally handles urban environments well, resisting damage from deer browsing.

Landscape Uses

The compact nature of Rudbeckia fulgida ‘City Garden’ makes it incredibly versatile in landscape design. Its upright form is perfect for adding punchy color to the front of sunny borders, cottage gardens, or foundation plantings where taller varieties might overwhelm the view. Consider using this Black-eyed Susan in mass plantings to create a cohesive block of brilliant yellow across a meadow area or rain garden setting.

Because this coneflower is robust and handles various soil types, it blends well with other drought-tolerant perennials that share a full sun requirement. Pair it with structural plants like ornamental grasses or contrasting textures such as blue-flowering Salvia or Russian Sage for dynamic seasonal interest. Its suitability as a good cut flower also means it is a worthy inhabitant of cutting gardens.

For city gardeners or those with limited space, the roughly one-foot height of Rudbeckia fulgida ‘City Garden’ is a significant advantage, ensuring structure without excessive bulk. It also performs admirably when planted in containers, offering portable summer fireworks that cheer up patios and balconies.
