Aeonium simsii, commonly known as Sempervivum, is a distinctive succulent with a rosette growth pattern. The leaves of the plant are fleshy and thick, typically forming a tight cluster. They have a glossy appearance and can have a green to reddish hue depending on the level of sun exposure and other environmental factors. Edges of the leaves might be tinged with a darker color, creating a beautiful contrast with the overall leaf color. The leaves usually spiral around the center of the rosette, creating a symmetrical pattern that is pleasing to the eye. The plant may produce flowers on a stalk that emerges from the center of the rosette, and these flowers are often yellow or pink. As a succulent, Sempervivum is adept at storing water within its leaves, making it a fleshy and somewhat plump plant to the touch. The surface of the leaves can be smooth with a waxy coating to help retain moisture. The plant is known for its durability and ability to withstand dry conditions once established.

  • skullToxicity

    • To humans

      Aeoniums, generally speaking, are not listed as poisonous to humans. However, any plant material may cause a reaction in certain individuals if ingested or if the sap comes into contact with the skin. That being said, ingestion of Aeoniums might cause stomach discomfort, vomiting, or diarrhea in some people. It is always advisable to keep plants away from small children who might put parts of the plant in their mouths out of curiosity.

    • To pets

      Aeoniums are not commonly known to be toxic to pets; they are typically safe around cats and dogs. However, as with any non-food plant, ingestion of large quantities could potentially lead to gastrointestinal irritation, vomiting, or diarrhea in some pets. If a pet ingests a part of an Aeonium and you notice any signs of illness, it is recommended to consult a veterinarian. It's best practice to keep plants out of reach of pets to avoid any potential issues.

  • water dropWater

    The Aeonium simsii, also known as "Houseleek Tree," prefers a watering routine that allows the soil to dry out slightly between waterings. Generally, watering once a week during the active growth season in spring and summer is sufficient. Provide approximately 8-16 ounces of water to the plant's base, ensuring you wet the soil thoroughly without leaving the plant waterlogged. During the winter dormant period, reduce watering to once every other week or less, depending on the humidity and temperature of your home environment. It's important to avoid overhead watering to prevent moisture from accumulating in the rosettes, which can lead to rot.

  • sunLight

    Houseleek Tree thrives best in bright, indirect sunlight. It can tolerate direct morning sun, but should be protected from harsh afternoon sun to prevent scorching of its leaves. A spot near a south-facing window with some light shade or a sheer curtain is ideal. If outdoors, provide dappled shade or a location with morning sunlight and afternoon protection to maintain the vibrant color and health of the Aeonium simsii.

  • thermometerTemperature

    Houseleek Trees prefer temperature ranges between 40 to 100 degrees Fahrenheit. They can tolerate minor frosts for short durations but should be protected from temperatures below 30 degrees Fahrenheit. The ideal temperature range for these succulents is between 65 and 75 degrees Fahrenheit. Keep them in an environment that avoids drastic temperature changes, as this can cause stress to the plant.

  • scissorsPruning

    Pruning the Houseleek Tree is mainly done to remove any dead or damaged leaves to maintain its appearance and health. Prune sparingly, usually once a year in early spring before new growth starts. This is also the time to shape the plant if necessary, by trimming back any overgrown branches. Using clean, sharp scissors or pruning shears, make your cuts at a slight angle to avoid damaging the healthy parts of the plant.

    Aeonium simsii, commonly known as Aeonium or Sempervivum, thrives in a well-draining soil mix with a pH around 6.0 to 7.0. A good recipe for Aeonium soil is a blend of 50% potting soil, 25% perlite, and 25% coarse sand. This will allow for proper drainage and aeration, preventing root rot and supporting healthy growth.

  • plantRepotting

    Aeoniums, often referred to as Tree Houseleek, should be repotted every two to three years to refresh the soil and allow room for growth. It's best to repot in the spring or early summer, which is the beginning of their active growth period.

  • circleLife cycle

    The Aeonium simsii, commonly known as Simsii's Aeonium, starts its life cycle as a small seed that germinates in well-draining soil during the cooler, moist seasons, typically in spring or fall. After sprouting, it enters a juvenile phase where it develops a rosette of succulent leaves and begins to establish a shallow but extensive root system. As it matures, the Aeonium simsii enters a vegetative stage, characterized by the growth of more rosettes that may branch from the main stem, leading to a fuller plant with more leaves for photosynthesis. Once reaching maturity, it enters the reproductive stage, producing pyramidal inflorescences with yellow, star-shaped flowers, usually in late winter to spring. After pollination, these flowers will set seed and then the plant itself often dies, as Aeoniums are monocarpic, meaning they flower once and then perish. The seeds disperse to begin the next generation, continuing the life cycle of the Aeonium simsii.

      Spring-Early Summer

    • The most popular method of propagating an Aeonium simsii, commonly known as Sims' aeonium or Aeonium 'Sunburst', is through stem cuttings. This is typically done during the plant's dormant period, which is usually in the summer for this succulent. To propagate, one would take a healthy stem cutting of about two to four inches (5-10 cm approximately) and allow the cut end to callous over for several days. Once the end has dried and formed a slight callus, the cutting can be planted in a well-draining soil mix. The soil should be kept slightly moist but not wet, and the cutting should be placed in bright, indirect light until it begins to take root, which generally takes a few weeks. After rooting, the young plant can continue to grow in more direct sunlight and should be cared for like any mature Aeonium simsii.
