Daylily Diamond Back

Daylily ‘Diamond Back’ is a commanding tetraploid introduction by Polston from 2013, notable for its exceptional height, large blooms, and dramatic toothy edging. This cultivar brings strong vertical presence to the garden along with rich, earthy coloration and dependable rebloom.

The impressive 7-inch blooms open in deep copper-rust tones, highlighted by a yellow-green throat that adds brightness and contrast at the center. A bold gold toothy edge frames the petals, giving the flower texture and definition while reinforcing its rugged, powerful appearance. The coloration is warm and saturated, holding well through the bloom cycle.

Plants reach approximately 40 inches tall and feature dormant foliage, making them well suited for colder climates. Blooming midseason with reliable rebloom, ‘Diamond Back’ produces around 15 buds on 4 well-spaced branches, delivering a balanced and extended floral display.

A tall, dramatic daylily ideal for borders, focal plantings, and collections emphasizing strong color, height, and toothy edge detail.
