Stinking Tutsan Hypericum hircinum
Hypericum hircinum, commonly known as the Stinking Tutsan, is a flowering plant that has a distinctive appearance. The plant boasts an array of yellow flowers that are quite showy when in full bloom. These flowers typically have five petals each and may feature numerous, conspicuous stamens that extend outward, giving the flowers a frilly, textured look. The petals themselves may have black or dark spots, which add to the visual interest of the blooms. The leaves of the Stinking Tutsan are dark green, glossy, and have an elongated, oval shape with a somewhat pointed tip. They are arranged oppositely along the stems, creating a symmetric, orderly appearance. Some describe the leaves as having an aromatic, peculiar scent when crushed, which is not always pleasant - hence the "stinking" descriptor in the common name. The stems of the plant are typically woody at the base, turning more herbaceous and green as they rise toward the flowers. Depending on the plant's stage of growth and the time of year, it may also bear fruit. These fruits can vary in color as they mature, starting as green and turning to a reddish or purplish hue. The fruits are small, berry-like, and may have a glossy finish that catches the light. Overall, the Stinking Tutsan's combination of showy yellow flowers, glossy green foliage, and distinctive scent make it a unique addition to the environments where it thrives.
About this plant
Stinking Tutsan, Stinking St. John's Wort.
Hypericum hircinum, commonly known as stinking tutsan, has not been predominantly classified as a toxic plant to humans in the mainstream literature. However, since it is a species of Hypericum, it might contain hypericin, as do other species within this genus which can cause photosensitivity when ingested in large quantities. In such cases, symptoms can include skin irritation, especially upon exposure to sunlight. It's also important to note that individual allergies or sensitivities may lead to adverse reactions not broadly documented. So, while the common usage of stinking tutsan does not usually include reports of significant toxicity, as with any plant, caution should be advised, and it should not be ingested.
Stinking tutsan, or Hypericum hircinum, is not well-known for being a major toxic threat to pets such as cats and dogs. That being said, its relation to other Hypericum species suggests that it could contain compounds like hypericin which may lead to photosensitivity in animals if they consume large amounts of the plant. Photosensitivity might manifest as skin irritation and dermatitis, particularly when the pet is exposed to sunlight. Although detailed reports on stinking tutsan's toxicity to pets are scarce, it is generally recommended to prevent pets from ingesting plants that are not part of their typical diet to avoid potential adverse reactions.

For the St. John's Wort (Hypericum hircinum), it is important to maintain moist but not waterlogged soil. Watering should be done when the top inch of soil feels dry to the touch. Typically, this plant will need to be watered once or twice a week, but this can vary depending on temperature and humidity levels. During hot and dry periods, it may require more frequent watering. Use approximately one gallon of water per plant during each watering session, ensuring the water penetrates deeply into the root zone.
St. John's Wort prefers full sun to partial shade. The best spot for this plant would be an area that receives at least six hours of direct sunlight each day, but it can tolerate some light shade, especially during the hottest part of the day. Avoid placing it in deep shade as this can result in fewer blooms and a leggy growth habit.
St. John's Wort thrives in a wide range of temperatures, but the ideal range is between 60°F and 70°F. It can survive minimum temperatures down to around 50°F and maximum temperatures up to approximately 90°F. It is generally considered hardy and can withstand mild frost without significant damage.
Pruning St. John's Wort is important to encourage bushier growth and to remove any dead or diseased branches. Prune in early spring before new growth begins. Generally, about one-third of the oldest stems can be cut back to the ground to rejuvenate the plant. It is not necessary to prune this plant annually, but doing so can keep it looking tidy and may enhance blooming.
The best soil mix for Stinking Tutsan should be well-draining and fertile, with an ideal pH of 5.5 to 7. A mix of two parts loam, one part peat or compost, and one part sand or perlite is suitable.
Stinking Tutsan does not require frequent repotting; every 2-3 years is usually sufficient, preferably in the spring.

- Life cycle
Hypericum hircinum, commonly known as Stinking Tutsan, begins its life cycle as a seed, often dispersed by wind or animals, which germinates in favorable conditions of damp, well-drained soil. Upon germination, the seedling emerges, establishing a root system and producing its first leaves. As the plant matures, it develops a woody base and herbaceous stems, with foliage that is generally evergreen in milder climates. During the flowering stage, Stinking Tutsan produces yellow flowers with a strong, musky odor in summer, attracting various pollinators for sexual reproduction. After pollination, the flowers develop into berry-like fruits, which start green and turn red to black upon ripening -- these contain seeds that will spread to commence a new generation. Finally, as part of the perennial cycle, Stinking Tutsan may enter a period of dormancy during adverse conditions, particularly in colder climates, only to regrow from its base the following spring.
Spring to Summer
Propogation: For the Stinking Tutsan, Hypericum hircinum, the most popular method of propagation is through seed sowing. Ideally, this is done in the fall, just after the seeds mature. Seeds should be sown in a cold frame or a sheltered outdoor area where they are protected from the winter elements. The soil mix should be light and well-draining, and the seeds need to be barely covered, as light aids in germination. It can take several months for Hypericum seeds to germinate, and consistent moisture should be maintained. Once seedlings are large enough to handle, typically in the spring, they can be transplanted individually into pots to grow on before being moved to their final position in the garden.
