Rudbeckia triloba 'Prairie Glow'
brown-eyed Susan 'Prairie Glow'
This vibrant perennial, commonly grown as an impressive summer and autumn annual, produces masses of small, daisy-like blooms with dark brown centres and petals that blend deep red-orange with yellow tips, creating a fiery, two-toned effect. Each flower is slightly different, adding movement and variety to borders from midsummer into autumn.
Dark stems and slightly bristly foliage provide extra texture and contrast. Although short-lived, it self-seeds readily in the right conditions, ensuring it reappears in future seasons.
Rudbeckia triloba ‘Prairie Glow’ thrives in full sun and well-drained soil, and works beautifully with ornamental grasses, salvias, and late-flowering asters. Its long flowering season makes it an excellent choice for adding late-summer warmth and supporting pollinators well into autumn.

How to care for Rudbeckia triloba Prairie Glow:
Plant out after the last frost, choosing a sunny position with well-drained soil. Water regularly during dry spells in their first few weeks to help them establish, but avoid waterlogging. Apply a general-purpose fertiliser in early summer to encourage strong growth and flowering.
Deadhead faded blooms regularly to prolong the display, or leave some seed heads in late autumn for wildlife and self-seeding. Tall stems may need staking in exposed sites to prevent wind damage. Remove spent plants after flowering if you don’t want them to self-seed, or allow them to drop seed for future plants.

Sowing instructions:
Using seed trays and good-quality seed compost, sow from late winter to mid spring, covering the seed very lightly or just pressing it into the surface, as light can help germination. Keep the compost moist but not wet and maintain a temperature of 18-20°C (64-68°F).
Transplant seedlings into individual pots when large enough to handle and grow on in cool, frost-free conditions. Harden off before planting outside after last frost, spacing plants to allow good airflow.
