Which Daylilies are best for my climate?
Daylilies are available with Evergreen, Semi-Evergreen or Dormant (deciduous) foliage. You should keep the following guidelines in mind when ordering daylilies for your garden.
Dormant plants can grow well in areas with winter temperatures down to -35 degrees Fahrenheit. They may grow in mild winter climates but they might not get enough winter chill to perform well.
Evergreen plants can take temperatures down to -20 Fahrenheit but need a 4-6 inch layer of mulch.
Semi-Evergreen plants vary. This designation is used by hybridizers when dormant or evergreen is not an adequate description.
The USDA planting zone map is based on the average annual minimum winter temperature, divided into 10-degree Fahrenheit zones. We recommend these general guidelines for planting daylilies:
Dormant Plants USDA Zones 3-9
Semi Evergreen USDA Zones 5-11
Evergreen USDA Zones 8-11
