In reference to replanting using crowns, later harvested crowns perform better the subsequent year than ones harvested early and therefore stored longer.
From the Greek “koris” (a bug) and “opsis” (indicating resemblance), referring to the seeds, which look like ticks.
The Compositae or aster family is vast, with over 20,000 species, and is also one of the most developed families. It was named Compositae because the flowers are actually a “composite” of many individual flowers into one head. Hence, when children pull one “petal” off at a time, saying “she/he loves me, loves me not”, they are actually removing a complete flower, not just a petal.
The specific epithet name “grandiflora” means large flowers.
Recent Research Findings:
Yuan et al. (1995) determined that this species requires 6 developed leaves on a stem before flower initiation can proceed.
