What about it?

The daylily is a perennial that can grow up to 5 feet and has large orange or yellow blossoms. The plant appears as a large cluster of foliage with large stems that produce flowers in June and July. Each bloom will last for only a day but the entire cluster should bloom for several weeks.

What is it used for?

Daylilies make wonderful border plants. Some varieties are better suited for garden plantings than others. "Europa" is a variety used for erosion control on erosion-susceptible banks.

Where does it grow? How do we grow it?

Daylilies are relatively tolerant of most conditions. They prefer full sun to partial shade and well-drained soils. They should be spaced 3 feet apart when planted because they are so large and need much room to grow.

What are its primary problems?

Daylilies are not susceptible to any particular pests and the only problem you may run into is in trying to remove them. They are very adaptive and persistent. Very little maintenance is needed, except that you may want to remove the old blossoms for appearance's sake.

How do we propagate it?

Propagation occurs through division. In early spring or August, cut the roots 1/2 way back and the tops to 2 inch stubs. You can also divide large clumps into smaller ones with spading forks.
