As perennial flowers start their fall blooms of yellow and orange, one reliable plant blooms pretty in pink.

Magic lilies, also known as surprise lilies or naked ladies, tend to bloom in Iowa in late summer in a synchronized manner. If you see them popping up in one part of town, you’ll see them in another.

This year, they made an appearance around Aug. 3, about average for this easy-to-grow perennial.

The plants sport elegant daffodil-like foliage early in the season, which disappears with the summer’s heat. By late July or early August, pink flowers tinged in blue simultaneously pop up on bare stalks, seemingly out of nowhere.

Another name for the flower formally known as Lycoris squamigera — in  the amaryllis family — is resurrection lily.

Magic lilies are drought-tolerant and can grow in partial shade or full sun.
