Four O'Clock, Marvel of Peru

Did You Know?

Showy Four O' clocks have been used for dyes and their medicinal properties, both in prehistoric times and modern day. The Navajos boiled the flowers to make a light brown or purple color for dying wool. The Hopis used the roots of older plants to make a blood-strengthening tea for pregnant women, and to treat various other medical conditions. And The Acoma and Laguna pueblo tribes dried the leaves for smoking material.

June 2004

Some say it has a sedative property, but most people grow this plant for the showy flowers, no doubt the reason why it is also known as 'the Marvel of Peru'. This plant is considered a perennial sub-shrubs in my zone, but is grown as an annual in cooler regions, which is why I have it classified as an annual. Four o'clocks are easy to grow, are OK in part or full sun, are drought-tolerant and will thrive in most any soil. In fact, I tried to get rid of some, and it actually proved to be quite difficult to make sure I got all the tubers out! Their name derives from the fact that their flowers open in the late afternoon and stay open until the next morning, except on cloudy days when they open earlier. The fragrance of four-o'clocks is appealing, as is the fact that they attract hummingbirds to the garden. This year has been a great year for these plants, and although they are in a place that doesn't even get that much sun, the flowers are abundant. and sure enough, they open like clockwork, every afternoon. As someone who is somewhat chroologically challenged as I like to call it (others just call it "always late"), it's kind of funny to have plant that is better at knowing what time it is than I am, but then, these are the mysteries of nature at work. So it goes. I figure if Thomas Jefferson could grow this baby at his place in Monticello, I'm in good company...
