As needed
  • water dropWater

    The Tricolor St. John's Wort should be watered when the top inch of soil feels dry to the touch, which typically amounts to watering once a week. During the growing season, it may require more frequent watering, especially if conditions are hot and dry. Use a watering can or a hose with a gentle shower attachment to moisten the soil evenly without soaking it. A good guideline is to provide about 1 gallon of water per week, ensuring it reaches the root zone. During winter, reduce watering to every other week or less, depending on the plant's environment and the soil moisture level.

  • sunLight

    Tricolor St. John's Wort thrives in full sun to partial shade. The ideal spot would receive at least 6 hours of direct sunlight daily while being protected from the harsh afternoon sun, which could cause leaf scorch. Morning sunlight with dappled or partial shade in the afternoon is optimal for promoting healthy growth and vibrant foliage colors.

  • thermometerTemperature

    Tricolor St. John's Wort is hardy and can tolerate a temperature range from about 50 to 90 degrees Fahrenheit. The plant's ideal temperature conditions for vigorous growth are between 60 and 80 degrees Fahrenheit. While it can survive slight dips below 50 degrees Fahrenheit, prolonged exposure to freezing temperatures should be avoided to prevent damage to the plant.

  • scissorsPruning

    Pruning Tricolor St. John's Wort is important for maintaining shape and encouraging new growth. Trim back the plant in late winter or early spring before the onset of new growth. This helps to remove any dead or damaged branches and allows light to penetrate, promoting a bushier growth habit. Pruning can also rejuvenate older plants, allowing them to produce more flowers. It is often sufficient to prune once a year, but deadheading spent flowers throughout the growing season can encourage additional blooming.

    As needed

  • bambooSoil

    The Tricolor St. John's Wort prefers well-draining soil with a slightly acidic to neutral pH, typically around 6.0 to 7.0. An ideal soil mix could be composed of two parts loam, one part peat moss, and one part sand or perlite to ensure proper drainage. Ensuring organic matter in the soil will help retain moisture while providing good aeration and nutrients.

  • plantRepotting

    Tricolor St. John's Wort should be repotted every 2-3 years or when it has outgrown its current pot. The best time for repotting is in the spring as the plant resumes active growth, which allows it to recover and establish itself more easily in the new soil and container.

  • circleLife cycle

    Hypericum × moserianum 'Tricolor' commonly known as Tricolor St. John's Wort, begins its life cycle as a seed, which will germinate under the right conditions of warmth and moisture, usually in spring. Once germinated, the seedling emerges and starts to develop roots and shoots. As the plant grows, it forms distinctive variegated leaves of green, pink, and cream, and in the summer, it enters the flowering stage, producing yellow blossoms that are attractive to various pollinators. After pollination, the flowers develop into small capsules containing numerous tiny seeds, which will mature and be dispersed in late summer or autumn, enabling the spread of the species. In colder climates, Tricolor St. John's Wort behaves as a herbaceous perennial, dying back to the ground after frosts but regrowing from the root system in the spring. This cycle of growth, bloom, seed production, and dormancy continues annually, with proper care and favorable conditions ensuring the plant's survival and spread.

      Spring-Early Summer

    • The St. John's Wort 'Tricolor', known botanically as Hypericum × moserianum 'Tricolor', is often propagated by taking semi-hardwood cuttings during the summer months when the plant is actively growing. To propagate using this method, a gardener should select a healthy, non-flowering stem and cut a 4-6 inch (approximately 10-15 cm) section, making sure that several leaves are present. The lower leaves should be removed, and the cut end can be dipped in rooting hormone powder to encourage root development. The cutting should then be planted in a well-draining potting mix, ensuring that at least one node, the part of the stem where leaves emerge, is buried beneath the soil surface. The pot should be kept in a warm area with indirect light and maintained moist until the cutting has rooted, which is usually indicated by new growth.
