St. John's Wort grows from about 12 to 18 inches tall and no more wide than about 2 feet. Showcasing golden star-shaped flowers beginning early in the summer, they offer a bright addition to the garden. They are a perennial and are very easy to grow.
Because St. John's Wort grows so well and spreads so easily, pests are actually used as a natural way to limit its growth, so they aren't a common detriment to the plant. Certain beetles and even moths have successfully controlled large areas of St. John's Wort where it's growth was problematic.
The berries of St. John's Wort are a very common and popular accent used in floral designs as well. The berries range in a variety of colors, including brown, red, green, peach, and cream. While they are not necessarily fragrant the way other flowers are, they do have a smell when rubbed or cut that slightly resembles cocoa or coffee.
With uses that range from odd and interesting to beneficial, St. John's Wort is a fascinating plant with a rich history. Even better, it's easy to grow and care for.
