St. John’s wort is a deciduous, rounded shrub which occurs on rocky ground and dry wooded slopes. In the landscape it can be used as a shrub border, hedge, or to stabilize embankments. The dazzling yellow flowers attract pollinators of all sorts who collect pollen from this species, and it hosts the beautiful Gray Hairstreak Butterfly (pictured above).

Shipping Information

Plant Shipping Carton

At Direct Native Plants, we take many precautions to make sure your plants will arrive in the best condition possible.

Our perennials are grown in a 4” quart-sized pot. These plants are then cut back to fit our packaging, placed in a protective clamshell container (made from recycled materials), and then shipped to you in a cardboard box.

Trees and shrubs are grown in a 7” tall container (referred to as a 1-gallon pot), and depending on the species will be between 12” and 36”. We bag the root section of these plants to prevent them from drying out in transit and ship them in a tall cardboard box. PLEASE NOTE: These boxes can be shipped in bundles up to 6. After that we start a new package, so keep this in mind if you’re trying to get the best shipping rates.

Direct Native Plants supports the United States Postal Service, so your plants will ship via USPS Priority Mail. Orders ship out Monday through Wednesday of each week, and depending on how close you are to our nursery in Maryland, shipping will take anywhere from 1-4 business days.
