The cheerful yellow blooms of the native Shrubby St. John's Wort (Hypericum prolificum) bush, is one of the sunniest blooming shrubs you can find! A well-known medicinal and herbal plant, St. Johnn's Wort is no doubt a flower that will lift your spirits!

Bright, sunny yellow blooms like fluffy pom poms make for happy bees and other beneficial pollinators looking for pollen. They do not have much nectar but your summer to late-season blossoms will be humming with bumblebees! St. John's Wort is a handsome dense, rounded shrub with charming blue-green foliage.

Also known as Klamath Weed, St. Johnn's Wort develops shedding brown and orange bark for winter interest, and for florists, the well-known showy seed capsules turn from green to lustrous brown. Not only are these beautiful seedpods to add to floral arrangements, but also leave on the shrub to add winter texture, but these Wildlife shrubs welcome songbirds to eat the fall seeds.

Planting and Application:

Shrubby St. John's Wort is an informal and chipper little plant for mixed borders, cottage gardens, and native plantings! Their tolerance for a wide range of conditions allows them to thrive in prairies, meadows, and wetland areas like ponds and stream banks, Rain Gardens, and in fields, ditches, and along the harsh roadside conditions.

The beneficial insects these attract become food for your songbirds and their chicks, but other pollinators like bees and butterflies! Then songbirds and other migratory birds return in fall for the seeds! These mid-sized shrubs are colorful backdrops and make summer borders shine!
