Rudbeckia triloba 'Blackjack Gold' - 2026

Rudbeckia triloba 'Blackjack Gold' is a vigorous, clump-forming perennial with deeply lobed green foliage and striking golden-yellow daisy-like flowers with dark brown central cones. Blooming from midsummer into early autumn, it provides long-lasting, vibrant colour in borders, mixed plantings, and wildlife-friendly gardens. The upright, branching stems create architectural interest, and the flowers attract pollinators such as bees and butterflies, enhancing ecological as well as ornamental value.

It thrives in full sun in fertile, moist but well-drained soil and is low to medium-maintenance, benefiting from occasional deadheading to prolong flowering. Non-native to the UK, it is valued for its bright, reliable blooms, long flowering period, and suitability for naturalistic or mixed border plantings.
