Apple of Peru Plant Info

Apple of Peru (shoofly plant to some) is a half hardy perennial that’s usually grown as an annual in USDA zones 3 through 8. It can reach 5 feet (1.5 m.) in height by the end of the summer, and blooms for two to three months during the summer. It produces light purple to blue flowers that grow in a bell shape. Even though it blooms constantly, the flowers only last for about a day, and the apple of Peru plant only ever has one or two flowers in bloom at a time. In the southern U.S., people rub the leaves on their skin as a fly repellant and will set it out in a dish mixed with milk to attract and poison flies, earning it the alternate name shoofly. In addition to being poisonous to flies, it is also poisonous to humans, and should NEVER be eaten.

Growing Shoofly Plants

Are shoofly plants invasive? Somewhat. The plants self-seed very easily, and where you have a single plant one summer, you will have many more the next summer. Keep an eye on them and try to collect the big seed pods before they have time to drop to the ground if you don’t want them to spread too much. Growing shoofly plants is easy. Start your seeds indoors about seven to eight weeks before the last frost, then transplant them outside once the temps in your area are warm enough to do so. They like soil that drains well but will thrive in various types otherwise.
