Decades of dedicated breeding have produced nearly 100,000 different varieties of daylily (Hemerocallis). Newer selections with 44 chromosomes—twice the normal number—have bigger flowers and bigger, darker green leaves, so you get a much bolder statement in the garden, says Whitinger. Among his favorites are strawberry candy, which features yellow-and-pink blooms, and Webster's pink wonder, which has 13-inch flowers with spidery petals and a gorgeous chartreuse center.
