St. John's wort
Hypericum frondosum 'Sunburst'
St. John's Wort (Hypericum frondosum 'Sunburst') is a bushy, perennial shrub with an upright growth habit. Sunburst has vibrant yellow flowers featuring distinctive, bright-yellow anthers that bloom from summer to fall. Its yellow-green foliage is accented by dark red stems and buds, and its foliage turns bronze-red in the fall. It's a sun lover, though it tolerates some shade, and grows best in well-drained soil. Suitable for use as a specimen or in mass plantings, the brightly-colored foliage makes an attractive backdrop for garden beds. St. John's Wort 'Sunburst' is deer and rabbit resistant.

watering
St. John's wort (Hypericum frondosum 'Sunburst') should be watered deeply twice a week during the spring and summer months, and once a week during the winter months. After the initial watering, make sure the soil has had a chance to dry out before watering again. This will help to prevent over-watering, which can cause root rot. When watering, water until the soil is completely moistened. Do not add excess water, as this can lead to water-logging and root damage.
sunlight
St. John's Wort (Hypericum frondosum 'Sunburst') needs a minimum of 6 hours of direct sunlight every day for optimal growth. This plant enjoys full sunlight, but should be protected from the harshest midday sun and intense heat. It can even tolerate shade for part of the day, but prefers to have at least 4 hours of direct sun. When grown in shadier conditions, the flowers tend to be less robust. When planted outdoors, St. John's wort requires direct sunlight exposure in the early morning and late afternoon, and protection—by a tree or a shade cloth—in the hottest part of the day.
pruning
St. John's wort (Hypericum frondosum 'Sunburst') should be pruned in late winter or early spring as needed. Pruning should be done to keep the plant looking its best. Generally, only the brown or dead branches should be pruned. Heavier pruning may be necessary to keep the plant from becoming too large. You may also need to pinch the tips of the branches to encourage bushier growth.
