Bitterroot Lewisia cotyledon Regenbogen (mixed)
ABOUT
The Lewisia cotyledon 'Regenbogen' is commonly known as rainbow Lewisia due to its colorful mix of blossoms. This perennial plant features fleshy, spoon-shaped leaves that form a rosette at the base. The leaves are bright green and may have a slightly waxy or succulent appearance that aids in water retention. From the center of the rosette, flower stalks emerge, topped with clusters of attractive blossoms that can come in a variety of shades—pink, orange, yellow, white, and sometimes bicolored petals that can have gradients or stripes, lending to the name 'Regenbogen', which means 'rainbow'. The flowers are star-shaped with numerous narrow petals radiating from the center, creating a delicate and intricate look. The center of each flower often displays a contrasting hue with golden anthers that stand out against the vibrant petals. The overall impression of the rainbow Lewisia is one of a lush, vibrant tuft of greenery from which emerges a colorful array of starry blooms, providing an eye-catching display in any garden setting. The plant is appreciated for its drought tolerance and its brilliant, long-lasting flowers that add a splash of color throughout the blooming season.

ToxicityTo humans
Lewisia, also known as Siskiyou Lewisia or Cliff Maids, is not widely known for its toxicity to humans. There is limited information on whether Lewisia cotyledon causes any significant toxic effects when touched or ingested by humans. However, as with any plant, individual sensitivities can vary, and it is generally advised to avoid ingesting plants that are not specifically grown for consumption. If ingested, depending on individual sensitivity, symptoms might include gastrointestinal discomfort such as nausea, vomiting, or diarrhea. If you suspect poisoning from any plant, it is important to seek medical advice.
To pets
Siskiyou Lewisia, or simply Lewisia, is not commonly listed as toxic to pets, such as dogs and cats. Like most plants not intended for animal consumption, it could possibly cause mild stomach upset if ingested in large quantities. Watch for symptoms such as vomiting or diarrhea, as these are common signs of gastrointestinal irritation in pets. If you observe these symptoms or suspect your pet has ingested Lewisia, it is best to consult your veterinarian for advice.

WaterLewisia, commonly known as Cliff Maids or Rainbow Lewisia, should be watered sparingly. These plants prefer to dry out between waterings, so a good rule of thumb is to water them once a week or less frequently, depending on the humidity and temperature. The method of watering should involve pouring water directly onto the soil rather than spraying the foliage, to avoid rot. As for the amount, providing them with about 8-12 ounces of water every week should be sufficient, but always check the soil moisture level before watering again.
LightRainbow Lewisia thrives best in bright, indirect sunlight. A spot that receives morning sun and afternoon shade is ideal to prevent the leaves from scorching. Avoid placing them in full, harsh sunlight during the hottest parts of the day to maintain the vibrant colors and health of the leaves.
TemperatureRainbow Lewisia prefers a temperate range with cool nights and warm days. They can survive minimum temperatures down to about 20 degrees Fahrenheit, but the ideal temperature range for them lies between 40-75 degrees Fahrenheit. These plants may be at risk if exposed to temperatures above 90 degrees Fahrenheit for prolonged periods.
PruningPrune Rainbow Lewisia to remove dead or withered flowers and foliage to encourage new growth. Pruning is best done after the blooming season, usually in late summer or early fall. Do not prune too heavily; instead, focus on tidying up the plant to maintain its attractive appearance.
CleaningAs needed
SoilBitterroot prefers well-draining soil with a rocky or sandy component, akin to its native alpine environments. A recommended mix might include equal parts potting soil, coarse sand or perlite, and fine gravel or pumice. The ideal soil pH for Lewisia cotyledon, or Bitterroot, is slightly acidic to neutral, around pH 6.0 to 7.0.
RepottingBitterroot doesn't need frequent repotting; it should be done every 2-3 years or when it outgrows its container. Care should be taken when repotting to avoid damaging the fleshy roots.
Humidity & MistingBitterroot thrives in moderate to low humidity levels, typical of its native mountain habitat. Avoid high humidity conditions which can promote rot.
Suitable locationsIndoor

Life cycleThe life of Lewisia cotyledon, commonly known as Siskiyou lewisia, begins with seed germination, which typically occurs in late winter to early spring when moisture and temperature conditions are favorable. The seedlings develop into rosettes, a cluster of fleshy leaves close to the ground, a stage that may last for one or more seasons as the plant establishes itself. As the plant matures, it forms a deep taproot that helps it survive in rocky, well-drained soil. Flowering occurs in late spring to early summer, with clusters of star-shaped flowers blooming in a range of colors atop slender, leafy stalks. After pollination, typically by bees and other insects, the flowers develop into capsules containing numerous tiny seeds, completing the reproductive cycle. The plant may die back following seeding, but the taproot can give rise to new growth in the following growing season, making it a perennial.
PropogationPropogation time
Spring to early summer
The most popular method for propagating Lewisia cotyledon, commonly known as Siskiyou lewisia, is through seed sowing. This is best done in fall or late winter, allowing a natural cold stratification period which can be mimicked by placing the seeds in a refrigerator for about three weeks before sowing. After stratification, sow the seeds on the surface of a well-draining soil mix, as they require light for germination. Cover the container with a plastic wrap or a glass pane to retain moisture, and place it in a bright area with indirect light. Keep the soil consistently moist but not waterlogged. Seedlings will emerge in approximately two to four weeks at temperatures around 60 to 70 degrees Fahrenheit (15 to 21 degrees Celsius). Once the seedlings are large enough to handle, they can be transplanted into individual pots or into the garden.
