Rainbow Rhythm® Primal Scream Daylily (Hemerocallis ‘Primal Scream’) – Proven Winners®

Rainbow Rhythm® Primal Scream Daylily is a Proven Winners® perennial valued for its exceptionally large, vivid orange blooms and strong garden performance. This cultivar of Hemerocallis is known for its intense colour and extended flowering period, making it a standout feature in landscape plantings.

This herbaceous perennial forms a dense clump of arching, strap-like green foliage. In mid to late summer, it produces oversized, trumpet-shaped flowers in bright tangerine-orange tones. Each bloom lasts a single day, but the plant produces multiple buds per stem, ensuring a continuous display over several weeks. The flowers attract pollinators such as bees and butterflies.

Primal Scream Daylily is well-suited for borders, mass plantings, and mixed perennial beds. Its bold colour and reliable growth make it a strong focal point in both modern and traditional garden designs.

Care Tips ▾

Remove spent flower stalks once flowering has finished to maintain a tidy appearance. Foliage can be trimmed back after it naturally yellows in fall or cleaned up in early spring. Divide established clumps every few years if flowering begins to decline or plants become overcrowded. Daylilies are adaptable but perform best in fertile, well-draining soil. A moisture meter is a great way to gauge your plant's moisture levels.
