Are Daylilies good for planting in locations where nothing else will grow?
Mostly Yes. But remember these are plants not super plants! Daylilies are very salt tolerant and so will grow well near the seashore or on the roadside of salted roads. Daylilies also will tolerate very wet conditions and are also considered to be excellent drought resistant plants. Being that they die down to the ground each winter they will grow where woody plants would be damaged by ice or snow removal. DON’T expect daylilies to grow: Under the deep shade of pine trees, in a desert of sand, in a swamp which has standing water most of the year, in the trunk of your car or anywhere it is pretty much impossible to grow a plant.
