Description: A clump-forming, herbaceous Perennial with an upright habit. Pale to mid-green Basal Leaves are strap-shaped and arching. Rich, deep red daylily flowers have yellow throats and roughly triangular petals with rounded tips. The Blooms are held atop sturdy, vertical stems and are produced from mid to late summer. Hemerocallis 'Mallard' is a Tetraploid plant (it has double the usual amount of chromosomes) which gives this cultivar thicker flowers, foliage, and stems. The flower colours of Tetraploids are often richer than those with the usual amount of chromosomes.

The common name, daylily, refers to the fact that each individual flower only lasts one day, usually around 16 hours.
