  • skullToxicity

    • To humans

      The common name for Hyacinthus orientalis 'Jan Bos' is hyacinth. All parts of the hyacinth plant contain oxalic acid and other potentially toxic compounds, which can be harmful if ingested by humans. Symptoms of hyacinth poisoning can include intense nausea, vomiting, diarrhea, and abdominal pain. If the sap comes into contact with skin, it can cause irritation, redness, and dermatitis. Ingesting hyacinth bulbs, leaves, or flowers should be avoided as it can result in stomach upset and at worse, could lead to more severe symptoms such as trembling, excessive salivation, and even symptoms of depression if consumed in large quantities.

    • To pets

      In pets, hyacinths are considered to be toxic. Similar to their effects on humans, ingesting any part of the hyacinth can lead to symptoms such as vomiting, diarrhea, drooling, and general gastrointestinal upset. In severe cases, if a large amount of the plant, particularly the bulbs, is consumed, it can cause more serious signs such as changes in heart rate, increased respiratory effort, and possibly convulsions. Pet owners should prevent their pets from ingesting hyacinths to avoid these toxic effects.

  • water dropWater

    For Hyacinth 'Jan Bos', water thoroughly whenever the top inch of soil feels dry to the touch, typically once a week. Avoid waterlogging by ensuring the pot has good drainage. During active growth in spring, you might need to water more frequently. Use about half a gallon of water for outdoor plants, ensuring even distribution around the plant. Reduce watering after the blooming period and during the dormant phase in the fall.

  • sunLight

    Hyacinth 'Jan Bos' thrives in bright, indirect sunlight. Place the plant near a window that receives morning sun and partial shade in the afternoon to prevent leaf scorch. A north or east-facing window is an ideal spot for keeping your Hyacinth healthy.

  • thermometerTemperature

    Hyacinth 'Jan Bos' prefers cooler temperatures, ideally between 60°F and 70°F during the day and no lower than 55°F at night. They can survive temperatures down to 20°F once established but should be protected from frost. Keep Hyacinths away from heat sources to maintain their preferred temperature range.

  • scissorsPruning

    Prune your Hyacinth 'Jan Bos' by removing spent flower stalks after the blooms fade, which encourages bulb strength. Leave the foliage until it turns yellow and dies back naturally, usually in late spring or early summer. Pruning is typically done once a year after flowering.

    As needed

  • bambooSoil

    Hyacinth 'Jan Bos' thrives best in a well-draining soil mix with a pH between 6.0 and 7.0. A mixture of two parts loam, one part river sand, and one part peat or compost works well for this plant. Ensure the soil has good fertility and moisture retention but also allows excess water to escape to prevent bulb rot.

  • plantRepotting

    Hyacinths, including the 'Jan Bos' variety, do not need frequent repotting and can often be left undisturbed for several years. They should be repotted if the bulbs become overcrowded or after the flowering when the foliage has died back. Generally, repotting every 3 to 5 years is adequate.

    Hyacinth 'Jan Bos' prefers moderate humidity levels but is quite adaptable. It does not require a specific humidity level to thrive as long as the soil moisture is well maintained without waterlogging.

  • circleLife cycle

    The life of the common hyacinth (Hyacinthus orientalis 'Jan Bos') begins with a period of dormancy, where the bulb lies inactive in the soil. Upon the arrival of favorable conditions, typically in early spring, the bulb awakens and sprouts, sending up leaves and a flower stalk. The leaves photosynthesize and provide energy for growth, while the flower stalk matures and blooms with fragrant flowers. After flowering, the blooms eventually wither, and the plant channels energy back into the bulb as the foliage dies back. The bulb then enters another period of dormancy during the hotter summer months, conserving energy for the next growing season. This cycle repeats year after year, with the bulb potentially producing offsets (baby bulbs) alongside, which can be separated to propagate new plants.

    • Propogation time

      Early autumn

    • The common hyacinth, specifically Hyacinthus orientalis 'Jan Bos', is typically propagated by dividing its bulbs after the foliage has died back, usually in late summer or fall. The most popular way to propagate this plant is by bulb offsets, also known as "daughter bulbs." These are the small bulbs that form at the base of the parent bulb. Once the foliage of the hyacinth has withered, usually by early summer, the bulbs can be gently lifted from the soil and the offsets carefully detached. The offsets should be about the size of a nickel (roughly two centimeters in diameter) to ensure they will flower in the following season. These daughter bulbs should then be planted immediately at a depth of approximately 6 inches (15 centimeters) and spaced around 4 inches (10 centimeters) apart in well-drained soil. This method ensures genetic consistency, as the new plants are clones of the parent.
