Hemerocallis Black Eyed Susan (Reblooming Daylily)
Regarded as one of the most consistent reblooming daylilies in northern regions, Hemerocallis 'Black Eyed Susan' is a compact perennial boasting a profusion of large, rich butter yellow flowers, 5.5 in. across (14 cm), adorned with a red-purple halo. Blooming in midsummer, and again later in the season, the attractive blossoms are held neatly above a compact mound of arching, linear leaves. Each flower typically lasts no more than 24 hours (thus the common name 'Daylily'), opening up in the morning and withering during the forthcoming night, possibly replaced by another one on the same scape (flower stalk) the next day. This midseason tetraploid daylily is dormant (deciduous). Excellent for mass plantings, erosion control, and perennial borders.
- Honorable Mention of the American Daylily Society in 1990.
- Grows up to 26 in. tall (65 cm) and 12-18 in. wide (30-45 cm).
- Thrives in full sun to part sun in average, moist, but well-drained soils. While it performs well in a wide range of soils, fertile loam is preferred. Tolerates heat and summer humidity, but thorough watering is required to ensure its foliage remains attractive.
- An ideal choice for beds and borders, cottage gardens, coastal gardens, rock gardens, as a ground cover, or in containers near the patio.
- Often called the 'perfect perennial' because of its numerous qualities: showy flowers, drought tolerance, heat stress immunity, ability to grow in most hardiness zones, and low care requirements, this daylily is a remarkable and stunning addition to the garden.
- Daylilies attract butterflies and hummingbirds but are toxic to cats. Rabbits tend to avoid daylilies.
- No serious pest or disease issues. Keep an eye out for mites, aphids, thrips, or daylily rust.
- The best time to plant Daylilies is in early fall or early spring.
- After flowering, remove spent blooms and seedpods to improve the appearance and encourage rebloom. When all the flowers on a scape are finished, cut off the scape close to ground level. Remove dead foliage from daylilies as they die back in the fall.
