Tweedy lewisia


Lewisiopsis tweedyi, commonly known as Tweedy's lewisia, is a perennial plant that is particularly noted for its attractive flowers and foliage. The plant typically forms a rosette, a circular arrangement of leaves growing close to the ground. These leaves are fleshy, often described as succulent, with a spoon-shaped appearance, sporting a smooth to slightly serrated edge. They can present a lush green color and may sometimes exhibit a reddish tinge on the margins under certain growing conditions. The flowers of Tweedy's lewisia are its most striking feature. They appear on stout stems that rise from the rosette of leaves. Each flower is sizeable and showy with multiple petals arranged in a radial symmetry, resembling a small cup or bowl. The blooms come in an array of colors, including shades of pink, orange, yellow, and white, often with contrasting veins or centers that add to their ornamental appeal. The blossoms may also display subtle color gradients, blending from one hue to another toward the center, and are known for their ability to attract pollinators like bees and butterflies. The blooming period of Tweedy's lewisia generally occurs in late spring to early summer, which is when this plant reveals its full splendor through its abundant and colorful floral display. After flowering, the plant will produce seed capsules, although the visual interest at this stage is less compared to the peak blooming season. Throughout its lifecycle, Tweedy's lewisia provides an attractive element to rock gardens, alpine collections, and areas of the garden where the beauty of its flowers can be appreciated up close. The plant is valued for its rugged beauty and the hardiness that allows it to thrive in rocky, well-drained soils.

  • water dropWater

    Tweedy's lewisia requires consistent moisture, but it's important not to overwater, as this can lead to root rot. Water when the top inch of soil feels dry to the touch, providing about one inch of water per week. In hot or windy weather, you may need to water more frequently to ensure the soil stays moist but is not waterlogged. During the winter months, water less often, allowing the soil to dry out more between waterings. It's best to use a watering can or a hose with a gentle spray to water at the base of the plant, avoiding wetting the foliage.

  • sunLight

    Tweedy's lewisia thrives in full sunlight to partial shade. The ideal location is a spot where the plant can receive at least six hours of sunlight per day. However, in particularly hot climates, some afternoon shade can prevent scorching of the leaves. Morning sunlight with partial afternoon shade is often an ideal balance for the healthiest growth.

  • thermometerTemperature

    Tweedy's lewisia prefers cool to moderate temperature conditions and is hardy in a range spanning from approximately 20°F to 75°F. However, ideally, they flourish in temperatures between 60°F and 70°F. They are not suited to extreme heat or prolonged freezing temperatures, and a drop below 20°F can be harmful.

  • scissorsPruning

    Prune Tweedy's lewisia to remove dead or diseased foliage, which can help prevent the spread of disease and improve air circulation. Deadheading spent blooms will encourage more flowering. Pruning is best done in early spring or just after the blooming period to allow new growth to emerge.

  • circleLife cycle

    Lewisiopsis tweedyi, commonly known as Tweedy's lewisia or Tweedy's bitterroot, begins its life cycle as a seed, typically germinating in the cool, moist conditions of late winter or early spring. Once the seed sprouts, it develops a rosette of succulent leaves close to the ground as it enters the vegetative stage, gathering energy through photosynthesis. As warmer weather arrives, it progresses to the flowering stage, producing attractive flowers that range from white to pink, with each capable of attracting pollinators. After successful pollination, the plant sets seed, which then matures within a capsule that eventually dries and releases the seeds back into the environment. Throughout the summer or as conditions become drier, Lewisiopsis tweedyi may go dormant, ceasing aboveground growth and relying on its thick taproot to survive through adverse conditions until the next favorable growth period. This perennial plant repeats this cycle annually, living for several years and spreading gradually as its seeds are dispersed in the environment.

    • Propogation time

      Spring-Early Summer

    • Propogation: Lewisiopsis tweedyi, more commonly known as Tweedy's lewisia or Tweedy's bitterroot, is best propagated through seed sowing. For successful germination, seeds should be sown in late fall to early winter, allowing them to experience a natural cold stratification process, which improves sprouting. Sow the seeds on a well-draining potting mix, lightly covering them with soil. The pot should be watered carefully to keep the soil moist, but not waterlogged, and placed in a bright, but not directly sunny, location. Germination can take several weeks, and it’s important to maintain consistent moisture and temperature during this period to ensure the seeds have the best chance at sprouting. Once seedlings are large enough to handle, they can be transplanted into their own pots or suitable locations in the garden.
