Hypericum androsaemum

The sweet-amber plant (Hypericum androsaemum), native to Europe, is a densely-branched shrub that grows up to 6 feet in height. Its bright yellow flowers are shaped like stars, with five petals and yellowish-green centers, and they bring a sweet, honey-like fragrance to the air. The leathery, dark green leaves are narrow and oval-shaped, and they blanket the shrub throughout the year. In autumn, the shrubby flowers produce red berries that last through winter. Sweet-amber makes an eye-catching addition to any garden, and it requires very little attention to thrive.

watering

When watering a sweet-amber plant, water it deeply once a week when the soil is dry. The soil should remain moist, but not overly wet, as too little or too much water can prevent the flowers from blooming. Water the plants around the edges of the pot, taking care not to get the flowers wet. The sweet-amber plant likes to be watered evenly and frequently and will need more water during hotter times of the year. Consider also misting the plants throughout the summer to replicate their native growing conditions.

sunlight

Sweet-amber (Hypericum androsaemum) is a plant species that requires partial to full sun exposure in order to thrive. Ideally, sweet-amber should receive at least 6 to 8 hours of direct sunlight during the warmer months of the year (April through October). During the cooler months, sweet-amber should receive 4 to 6 hours of direct sunlight each day. In addition to sunlight, sweet-amber also requires regular watering throughout the growing season.

pruning

Sweet-amber (Hypericum androsaemum) does not require much pruning. If necessary, prune in late winter or early spring before new growth begins. First remove any dead, wilted or diseased branches. Then, cut back leggy, straggling growth, crossing branches and excessive sucker growth. Remove no more than 1-third of the growth, and always cut back to a bud or branch junction. This will encourage a dense shape and encourage flowering. If the plant has become too leggy, it can be cut back to the ground level for a new start.
