Awards, except for All-America, are given by the American Hemerocallis Society.
Abbreviations used in the plant descriptions are given below:
EE: Begins blooming extra-early season
E: Begins blooming early season
EM: Begins blooming early and mid-season
M: Begins blooming mid-season
ML: Begins blooming mid and late season
L: Begins blooming late season
re-bloom: Varieties may have more than one set of bloom scapes, either one right after another or with a break in between.
Southern gardeners can expect more rebloom because of their longer season.
Tetraploids and Diploids: These terms designate whether a variety has eleven pairs of chromosomes (diploids) or twice as many (tetraploids). If you want to hybridize, you must cross diploids with diploids and tetraploids with tetraploids. On this website and in our catalogs, tetraploids are marked with an asterisk (*).
Dormants and Evergreens: Daylilies vary from dormant varieties (the leaves die completely to the ground in the winter) to evergreen varieties (the leaves try to grow whenever it gets warm) with various degrees of semi-evergreens in between. Gardeners from USDA zones 9 and 10, and other areas that do not have a cold period in the winter should buy only evergreen or semi-evergreen varieties. Northern gardeners in zones 4 or colder may want to stick with dormant varieties, although many semi-evergreen and evergreen varieties will grow well, especially if mulched. One other note: in zones 7/8 and colder, the foliage will typically be frozen to the ground regardless of foliage type.
