What makes South Dakota daylilies so tough? They must endure the following:
Winter – 35F degrees below zero with no snow cover
Summer – heat up to 115F.
Dry – So little moisture in the air, it can dry a daylily to death
Soil – very alkaline
Rainfall – Only 13″ average annual rainfall. Not enough to keep a daylily happy.
Other – Hail, hail, and more hail. We don’t even count pea size hail storms. One year had 12 hail storms. The flowers have to be able to take it.
For a daylily to survive South Dakota, it has to be extra tough, so they will grow other places with ease and be very happy, bigger and have more flowers than here in Rapid City.
