St. John’s Wort

Have a large backyard? Give it the look and feel of an open meadow by planting St. John’s wort. This flowering plant spreads fast and far with stems both above and below ground, which is why we recommend it more for sprawling spaces than smaller gardens.

Originating from Europe and now found in most of the U.S., St. John’s wort is a summer stunner with bright yellow flowers. In fall, the flowers give way to berries. Choose a location with partial shade and use virtually any kind of soil. And remember, it’s going to spread aggressively, so give it plenty of space to transform your landscape.
