Many nursery catalogs advertise certain daylilies for their eblooming ability. How reliable are these claims?
Many daylily buyers use the reblooming characteristic as their primary criteria in selecting a daylily, but my thinking goes in a different direction. Rebloom, whether it happens or not, and the quality of the rebloom flowers, is highly dependent on culture, rainfall, fertilization, sunlight, and a whole host of environmental circumstances completely remote from plant genetics. Many daylilies that regularly send forth three volleys of scapes in central Florida may cut back to two in Missouri and only one in Ohio based solely on the length of the growing season. If you add in factors like insufficient fertilization, poor sandy soil, failure to remove seed pods, shade and drought, you may drop the rebloom line back to Arkansas. In other words, rebloom may not be something you can count on to carry your garden into late summer and early fall. When a plant is registered as reblooming all it means is that the genetic propensity is there and can show itself if all other conditions are right.
