Siskiyou lewisia Ashwood strain


The Lewisia cotyledon Ashwood strain, more commonly known as Siskiyou lewisia, is a striking perennial plant that is valued for its ornamental appeal. The main attraction of this plant is its rosette of fleshy, evergreen leaves that are spoon-shaped with smooth to slightly toothed edges. These leaves create a low-growing, basal clump from which flower stalks emerge. Its flowers are especially showy, blooming in a range of colors from white to deep pink, and can even showcase striking bicolor or multicolored petals. These blossoms are outfitted with numerous petals that radiate outwards, resembling a daisy or a star in shape. These petals surround a central cluster of stamens and pistils, yielding an intricate and eye-catching display. Each flowering stalk of the Siskiyou lewisia supports a cluster of these blooms, held aloft and presenting a dazzling floral display that rises above the greenery, attracting onlookers and pollinators alike. The blossoming of this plant typically occurs in late spring to early summer, adding seasonal charm to the garden. The Siskiyou lewisia is prized for its vibrant and cheerful blooms that make it an exceptional choice for rock gardens, alpine displays, or as a colorful accent in a mixed perennial border.

  • water dropWater

    For Bitterroot, a prudent approach is to water when the top inch of soil feels dry, typically once a week, but this can vary depending on temperature and humidity. During the growing season, water the plant generously, ensuring it receives an inch of water. In the dormant winter months, reduce watering to prevent root rot, providing just enough to keep the soil slightly moist. Avoid waterlogging by using well-draining soil and a pot with adequate drainage holes. Overwatering or letting the plant sit in water can lead to problems, so it's crucial to monitor the plant's response to your watering routine.

  • sunLight

    Bitterroot thrives in bright indirect light, but it can also tolerate some direct sunlight. The best spot for this plant would be in an east or west-facing window where it receives some morning or late afternoon sun. Too much direct sunlight can lead to leaf burn, while too little light can stunt growth and reduce flowering.

  • thermometerTemperature

    Bitterroot is best suited to temperatures between 40 and 80 degrees Fahrenheit. Extreme temperatures below 40 degrees or above 85 degrees can damage the plant. The ideal temperature range for this plant's growth is between 60 and 70 degrees Fahrenheit.

  • scissorsPruning

    Prune Bitterroot to remove dead or damaged foliage and to promote a compact, bushy growth habit. The best time to prune is in late winter or early spring, just before the new growth starts. This will also help rejuvenate the plant and encourage more blooms during its flowering season.

  • bambooSoil

    The bitterroot (Lewisia cotyledon 'Ashwood strain') thrives best in a well-draining soil mix with a slightly acidic to neutral pH of around 5.5 to 6.5. A suitable mix could include equal parts of loam, sand, and perlite or pumice to ensure good drainage which is vital for preventing root rot in this succulent plant.

  • plantRepotting

    The bitterroot should be repotted every 2 to 3 years to refresh the soil and accommodate root growth. Since they have a deep taproot, choose deep pots and be careful not to damage the root when repotting.

  • water dropsHumidity & Misting

    Bitterroot prefers moderate to low humidity environments, typical of its native mountainous habitats. It does not require high humidity levels and can tolerate dry air well, making it suitable for typical indoor environments.

  • circleLife cycle

    The Lewisia cotyledon, commonly known as Siskiyou lewisia or Cliff maids, begins its life cycle as a seed, typically sown in late winter to early spring. The seeds germinate and form rosettes of fleshy, evergreen leaves from which the root system develops to anchor the plant. In late spring to early summer, the plant enters its flowering stage, producing stems topped with clusters of star-shaped flowers in a range of colors, including pink, orange, yellow, and white. After pollination, often by bees and other insects, the flowers will set seeds that mature by late summer. The plant then enters a period of dormancy, especially in areas with hot summers or very cold winters, where growth slows or halts. In the following growing season, the plant resumes growth, and mature specimens may produce offsets, which can be separated and grown as new individuals, continuing the life cycle.

      Spring-Early Summer

    • The most popular method of propagation for the Lewisia cotyledon, commonly known as Siskiyou lewisia, is through seed sowing. This process is best done in the fall, allowing the seeds to experience a cold period or stratification, which helps improve germination rates. Sow seeds lightly on the surface of a well-draining soil mix, and just barely cover them with a thin layer of soil. The pots or trays should then be kept in a cool, well-lit place but not in direct sunlight; ideal temperatures are around 50 to 55 degrees Fahrenheit (10 to 13 degrees Celsius). Always maintain moist conditions, but avoid waterlogging as this can cause the seeds to rot. The first seedlings typically emerge in late winter or spring, and once they are large enough to handle, they can be transplanted into individual pots.
