Understanding Plant Options
Nature Hills offers plants in two main formats:
- Container Plants: Grown in pots with soil, sized by container volume and plant age

The cheerful yellow blooms of the native Shrubby St. John's Wort (Hypericum prolificum) are one of the sunniest blooming shrubs you can find! A well-known medicinal and herbal plant, St. John'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. John'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, and 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 that 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!

#ProPlantTips for Care:
St. John's Wort is a hardy native deciduous shrub that's incredibly easy to grow and low maintenance. In colder climates of USDA growing zones 3 to 8, it may even die back to the ground in harsh winters, but comes back strong each spring. Provide full sun locations and well-drained, moist soils for the best results. Mulched beds are best in drier sites and in colder climates. Prune if needed in the very early spring to control shape and size.
- Full Sun & Partly Shaded Sites
- Average Well-Drained Soil
- Tolerates Drought, Brief Flooding, Moderate Salinity & Rocky, Sandy or Clay Soil
- Pest Free & Often Left Alone by Deer
