"Dead-heading" Stella D'Oro and Shasta Daisies
Below is a response to the same question within the Ask an Expert system that I think will be helpful:
"There are many cultivars of daylilies. Their bloom time varies from early to late summer. Some cultivars produce more buds per scape or flowering stem. Select plants the bloom at varies times. Stella de Oro is a cultivar known for numerous buds or flowers per scape.It is best to remove seedpods after bloom to prevent seed production. Plants producing seed are likely to have fewer flowers the following year. http://www.extension.umn.edu/garden/yard-garden/flowers/growing-daylilies/ " Pat M. (Minnesota)
