Overview

Bold golden flowers with dark centres make this variety a standout choice for brightening summer borders. The daisy-like blooms are large, long-lasting, and highly weather resistant, appearing in succession from mid-summer into autumn. Sturdy stems rise to around 60cm (2ft) and carry bristly green leaves that provide a strong base for the display.

Rudbeckia hirta ‘Marmalade’ is most often grown as an annual, though technically a short-lived perennial, and is valued for its reliability and easy growing nature. It thrives in full sun and well-drained soil, and works well in beds, mixed borders, and large containers.

The flowers are also excellent for cutting, holding their colour and form in arrangements, while in the garden they attract bees and butterflies throughout the season.

Care guide

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.

Planting requirements

  • 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.
