Plant Type: Daylilies

The best yellow tetraploid daylily! 5", delightfully fragrant, clear citron yellow flowers with a bright green throat and heavily ruffled petals on well branched and heavily budded scapes ensure many weeks of bloom. Extended bloom–flowers last at least 16 hrs. each. Opens well after cool nights; a great choice for northern gardens. Blooms from early to midsummer. Tetraploid
This is considered a "Designer" daylily, which means that it has been selected as highly performing plant with exceptional bloom performance, substantive, vibrantly colored flowers, complete winter hardiness in northern zones, and a vigorous habit.


Growing & Maintenance Tips:

Daylilies can survive many harsh conditions that other plants cannot including: polluted city environments, slopes, poor and dry soils, near pavement that is salted in winter, and under Black Walnut trees (not affected by juglone). Daylilies are some of the easiest perennials to grow and are a good choice for any gardener, from the beginner to the professional. These are tough, adaptable plants that will grow in any soil, from normal to slightly wet to dry. Older varieties are able to bloom if planted in partial shade, but most of the newer introductions need full sun for best performance. Likewise, older varieties tend to spread more rapidly than the newer hybrids. All varieties can be divided every 3-4 years by digging up the entire clump and dividing it into smaller pieces with a minimum of 3 eyes each. This can be done in either spring or fall. Plants should be deadheaded for cosmetic purposes, but in most cases this will not extend the bloom time.
