St. John's wort

Hypericum moserianum 'Tricolor'

St. John's wort (Hypericum moserianum 'Tricolor') is a perennial flowering plant native to Europe and favored for its three distinct leaf colors. An easy-to-grow plant, it has bright yellow flowers and produces yellow-tinged foliage in spring. Its bright leaves—yellowish green, lime and cream-white—form mounds and add vibrant color to the garden. It tolerates a range of soils and requires full sun and regular watering. It can be used in borders, in rock gardens, and as an edging or ground cover. On top of its aesthetic appeal, St. John’s Wort also produces essential oils that may be used medicinally.

watering

St. John's wort (Hypericum moserianum 'Tricolor') should be watered deeply once every 7 to 10 days. Water should be applied until the soil is moderately moist but never soggy, allowing water to dry out between waterings. During the warmest months, St. John's wort may need watering more often than once every 7 to 10 days if the soil is drying out quickly. A thorough inspection of the soil is advised to determine when the next watering is necessary. Additionally, St. John's wort should always be watered at the base of the plant, avoiding wetting the foliage.

sunlight

St. John's wort (Hypericum moserianum 'Tricolor') prefers full sunlight but can tolerate partial shade. For optimum growth, it is best to provide this plant species with 6 to 8 hours of direct sunlight per day. Plants grown in full sunlight tend to develop more colorful blooms and foliage compared to those grown in partial shade. This plant should be placed in a sunny spot or near a south or west-facing window to ensure it is getting adequate sunlight.

pruning

St. John's wort (Hypericum moserianum 'Tricolor') should be pruned annually in late winter or early spring. Pruning should be done after the last frost date and before the plant blooms. This species should have only 1/3 of the total growth removed each year. Care should be taken not to over prune, as this can cause the plant to become weak and susceptible to disease. Additionally, dead or unhealthy branches should be pruned away any time of year to improve the plant's appearance.
