Daylilies are among my favorites flowers, though I am much less fond of double cultivars because most of the time produce single flowers. Of the 3 doubles I grow (Double River Wye, Siloam Double Classic and You Angel You), only Double River Wye is reliable. I grow about 40 cultivars of all sizes from tiny Cara Mia, Mini Pearl and Baby Talk to tall Fulvas, Ice Carnival and Catherine Woodbury, from almost white Sunday Gloves to purples (David Kirchoff, Little Grapette, purple d'Oro, Summer Wine). I do not grow fancy and pricy new hybrids but common cultivars are numerous enough to please most gardeners. I use some of the most common ones (fulva, Pink Damask, Stella d'Oro and Children's Festival) in slopes to prevent erosion. In 2 or 3 years the slope is well stabilized with bright flowers. And they tolerate transplantation well so I can move them as needed.
Without daylilies, my flower beds would be colorless for parts of the summer.
Here is a bloom of Destined to See planted in mid-shade with heavy hardwood mulch.
Among those I grow in part shade to mid shade, some cultivars seem more prone to slug attacks than other. Is it documented somewhere?
