American beautyberry

When beautyberries start producing their eye-catching, bright purple fruit in late summer, we start to get lots of questions. People want to know what it is, where can they find it, and can they eat it? While the berries look good enough to eat, it’s best to leave them to the birds and deer. They are not toxic and were used by Native Americans for a root tea to treat fevers, stomach aches, malaria, and more, but the taste has been described as bitter and mealy. Thanks to a generous volunteer, I am lucky enough to have tried beautyberry jelly. A little (or a lot) of sugar can make most anything taste good—and the finished product is a beautiful, translucent shade of fuchsia.

Even more interesting to me was the revelation that researchers have been able to extract compounds from beautyberry that successfully repel pest insects such as ticks and mosquitoes. The study began about 15 years ago, after a Mississippi botanist with the USDA Agricultural Research Service mentioned to a colleague that his grandfather taught him to rub the crushed leaves of beautyberry on his skin. The technique had been used as a home remedy to prevent mosquito bites for people (and horses) for generations. As a follow up experiment, another group of researchers found these same compounds—callicarpenal and intermedeol—successfully repelled black-legged ticks (which transmit Lyme disease) as effectively as DEET. In the last few years, researchers out of Mississippi have worked towards creating natural insect repellents from the compound that are less harsh on human skin that many commercially available brands.

Aside from its many practical uses, Callicarpa americana is a beautiful native shrub. It has wide green leaves and the brilliant purple berries grow in clusters along its stem. They stay on through late fall and winter in some places, making a beautiful contrast to fall foliage. Beautyberry shrubs can be found in a wide variety of habitats, including sandy and wet soils, full sun, and part shade. Their adaptability makes them a great plant for tight conditions like roadsides or yard edges, but also for nearly any home landscape. The plants can grow to a height of 4-8 feet and spread 3-6 feet wide. The long-lasting berries make them a great wildlife food source later in the cool season than many berry-producing species.

Tick Tips

You’ve probably heard some tips to prevent picking up ticks in the past, but did you ever wonder why some work and others don’t? Understanding the life cycle and behavior of common ticks can help you succeed with your prevention measures.

A general life cycle for ticks includes four life stages: egg, larva, nymph, and adult. The egg hatches into larva which require a blood meal to molt into a nymph which again requires a blood meal before molting to an adult.
The adult female also requires blood feeding in order to produce eggs, which she lays in high numbers – some species lay up to 6,500 eggs!
Because blood is required for development, ticks have to be resourceful in finding hosts. Knowing this can help you understand why some tips work better than others.
Tick Tips
  • Wear clothing that covers skin and avoid sitting on the ground or logs in brushy areas. Adult ticks exhibit a behavior called “questing” where they climb to the top of grasses and vegetation with their forelegs extended and wait for a host to come by.  The American Dog Tick‘s primary host are dogs, but they will also target cattle, horses, and humans.
  • Apply repellents to exposed skin and clothing (different products are labeled for where they are applied, follow all directions). These chemicals repel ticks and can reduce likelihood of tick attachment, but ticks have been known to crawl over treated areas to access untreated body parts.
  • Keep grass and vegetation maintained and clean up debris that may harbor small mammals and rodents. Early in the tick life cycle it targets smaller animals for blood and they can
    hide or shelter in debris piles and vegetation.
  • Always shower and check yourself for ticks after being in areas where ticks may live, especially when temperatures are warm. Nymphs can be less than 1 mm long, so check carefully!
