how far apart to plant daylilies
If you are planting to propagate new plants or for an instant mass of color that will persist for 3 to 5 years, go ahead and plant each plant so its longest leaves will touch the longest leaves of its neighbors. Set miniature plants and small daylilies like Stella DâOro an average of 8 to 12 inches apart from crown to crown. The original Stellas are a bit less compact than newer varieties, but most of them will form a dense mat if set 1 foot to 16 inches apart. Set medium-sized daylilies from 18 to 32 inches apart.
Set large daylilies from 32 to 48 inches or more apart. The original cultivar called âKwanso,â a double-petalled tawny lily with an extended period of bloom can spread as wide as 4 feet. Many tetraploid daylilies are bred for flower size and spider daylilies are bred for height; the plants may grow as large as or larger than their common cousin.
