Named for the brightest star system in the constellation Centaurus, this outstanding daylily is one of the brightest yellow flowered varieties in our fields. It has a very pronounced presence there as its tall, strong, top-branched scapes carry very large 6”, pure citron yellow, fragrant flowers with a lime green throat.
Use this daylily to add a brilliant beacon of color to the garden.
When appreciated up close, you’ll notice its lovely, fragrant blossoms have diamond dusted, ruffled petals too.
This is considered a premium 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.
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.
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.
Daylilies were eaten as food in China and Japan.
