One of the things that makes growing daylilies so popular is this beautiful perennial's adaptability. Though it has preferences about light and climate, there are few places so inhospitable that a daylily won't thrive there.

Climate Requirements: Daylilies are hardy just about everywhere - there are cultivars that are at their best in zones two and nine and varieties for everywhere in between. Because cultivars may be region-specific (bred to meet the growing requirements in a certain area) be sure to check the zone hardiness on any you purchase.

Take foliage pattern into consideration
Daylilies have three distinctive foliage patterns, and it's important to understand how climate can effect each foliage pattern:

Dormant: Some cultivars need a set period of dormancy each year, and that period is generally triggered by changes in temperature and daily light cycles. In climates where the temperature doesn't go below 40 degrees, there might not be enough of a change to trigger dormancy. These are the most commonly grown daylilies in northern regions. Semievergreen: In colder climates semievergreen daylilies will die back just as the dormants do, but in warm climates the foliage may stay green all year long. Evergreens: as the name implies, these varieties keep green foliage all year long. This makes them a popular addition to southern gardens, though many are also cold hardy. But in climates where the temperature varies enough to create repeated freeze-thaw cycles evergreen daylilies are at risk; many have a hard time recovering from frozen foliage.

Light Requirements: Daylilies are at their exuberant best spending most of their time in full sun, with perhaps a little partial shade during the hottest hours of the day. But these adaptable beauties will cooperate in less than ideal conditions.

A minimum of five or six hours a day of full sun in an open western or southern exposure is perfect, but if that's not possible daylilies will grow in much less light. With sufficient light daylilies are densely flowered, bushy, and compact, but in conditions with too little light they will be lankier, produce fewer flowers, and may lean toward the light.

Choose darker colors for areas of lower light
Generally speaking, the lighter the color of the flowers, the more direct sun the daylily requires to be at it's finest. Daylilies with dark flowers appreciate protection from the hottest afternoon sun, which can burn their petals.
