 Common Name: Daylily

Like a dark storm cloud rolling across our fields, this dramatic deep red daylily with a yellow halo and green throat commands a presence.  If you look closely, you’ll notice a wiry, cream edge half way around the pie crusted, velvety textured petals. 

The 5.5", fragrant blossoms appear on thick, branched stems atop robust, vigorous plants in midsummer.  This is an extended blooming, nocturnal variety so its flowers open the day before in late afternoon and remain open for at least 16hrs.

Dormant tetraploid.

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).

Homeowner Growing & Maintenance Tips:

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.

Daylilies can be divided every 3-4 years by digging up the entire clump and dividing it into smaller pieces with a minimum of 3 fans each. This can be done in either spring or fall. Plants can be deadheaded for cosmetic purposes, but in most cases this will not extend the bloom time.
