I've always been partial to plants that will 'persist for years once established.' Surprise lilies are hardy to USDA Zones 5-10 and require virtually no care. I remember the first time I saw them blooming in long rows along an old highway in Sonoma County, California. They do well in full sun, part shade, and even heavy shade and will thrive in both sandy and heavy clay soils.
The blooms are long lasting and make good cut flowers. The plants are mildly toxic, which may be part of the reason they're touted as deer resistant, though when
Cary was a baby she made a beeline
straight for the blooms and survived just fine. Other than her, I've never noticed any pests or insects bothering my plants.
Surprise lilies produce large bulbs (about 2 inches across) that multiply quickly and can be divided every 3 to 5 years. Buy bulbs in spring and fall or beg some from a friend's garden. I've never divided mine, but I probably should try it, especially since I wouldn't mind expanding my little patch.
Dig up the bulbs in spring—when it's easy to see the yellowing leaves—or after the blooms fade in August or September. Plant your bulbs in clusters as soon as possible after digging them up, 1 to 7 inches deep (the colder your climate, the deeper you'll want to plant) anywhere you'd like a showy summer display. If you don't mind a few wilting leaves, you can even plant them under the sod in your lawn, mowing around the stalks when they bloom.
Your surprise lilies may not flower for the first two years, and depending on weather conditions, they may not flower every subsequent year (which means a 'surprise' for you when they do). One source I found said the closer you plant the bulbs, the sooner they'll bloom, which may be why they make good potted plants.
