Looking for a cheerful plant to use throughout your garden? The ever-popular St. John's Wort Gemo (Hypericum kalmianum 'Gemo') is a top seller in Europe and would do very well in your landscape.

This compact, rounded shrub is covered in bright-yellow flowers at the end of the branches. Each bloom features five, wide-open petals.

Look closely in the center, and you'll see many erect, bushy stamens that add a fun dimensional effect to each flower. These buttercup-shaped blooms look like a glowing yellow star around showy pom-poms!

Gemo St. John's Wort is a wonderfully profuse variety that blooms from July until September. They will keep you smiling.

Don't you just love it when a plant delivers so much interest, over such a long period of time? You get your money's worth with Gemo St. John's Wort.

In the growing season, the shiny foliage looks just like willow leaves. It's very attractive in its own right, even before the blooms start their show.

With a bushy,multi-stemmed branch structure, Gemo looks great all year-long. The leaves are held densely from top to bottom of the shrub and look lush and full.

This easy-care flower factory can be grown across much of the United states. It performs beautifully in full sun, but can also handle a bit of shade through the day.

It's also a versatile plant that stays nice and small. You'll find many places to use it, including in seasonal outdoor containers.

Wherever you plant it, Gemo St. John will have people stopping and staring. Those unique blooms are a real standout in the garden. Order yours today!

How to Use Gemo St.John's Wort in the Landscape

Boost your curb appeal with a pair of outdoor containers flanking either side of your front door. Even if you are renting, these long-blooming plants can decorate your deck, balcony, patio or porch when grown in pots.

These tidy, little yellow-blooming shrubs can be used as a backdrop in a perennial garden. Partner behind Daylilies for a very low-maintenance, modern planting that looks incredible.

Create a small hedge by planting them 18 inches apart on center. You'll measure from the center of one to the center of the next.

Add them to the edge of your planting beds. It can also become a helpful "facer" plant for leggy shrubs, or perennials with bare lower stems.

They are especially useful when used on the east or south side of a shrub border. Try this with mature evergreen trees that frankly, need a little perk-me-up.

Honey bees, butterflies and beneficial pollinators love the fun and funky blooms. Gemo St. John's Wort makes a wonderful contrast in terms of growth habit, color and flower shape to Butterfly Garden host plants like Swamp Milkweed.

Add a row to your Herb Garden, or plant in large containers at the corners of your Victory Garden. You'll help pollination during the coveted "Second Summer" planting in your veggie patch.

This beautiful shrub can brighten up partially shaded areas in your landscape. Create long, irregular drifts along the sunny side of a woodland.

Line your walkways with a straight row of these happy bushes. Or, use in urban street plantings to lift the spirits of all who see it.

#ProPlantTips for Care

This personable shrub grows best in moist, well-drained soil. In other words, keep it watered on a regular basis, but make sure the roots don't sit for long in standing water.

Keep container plants well watered through the growing season. Apply a good drink before you turn off your sprinkler system for the winter.

Lightly prune to shape in early spring after you start seeing new growth. You can tip-prune during bloom time, but only if you bring the flowers inside for beautiful cut flower arrangements!

This is a good choice in areas with heavy deer pressure, as they don't prefer the taste. However, no plant will stand up to a hungry deer. Use deer repellent and reapply according to directions.

It easily tolerates urban conditions and road salt. Support the blooms with an application of organic, slow-release fertilizer in early spring, following instructions on the package.

Make your landscape "pop" with the bold blooms of Gemo St. John's Wort. Order today!
