Cardamine bulbifera, commonly known as Coralroot, is a distinctive plant with a charming appearance. The plant primarily showcases a basal rosette of rounded to heart-shaped leaves that are rich green in color. During its blooming period, Coralroot produces slender stalks topped with small lilac to pink flowers. These blossoms are characterized by their four delicate petals forming a cross shape, a typical feature of plants in its family. The stems are smooth and upright, forming a gentle contrast with the foliage below. Coralroot is also notable for its bulbils - small bulb-like growths - which can be found at the bases of the upper leaves on the flowering stem. These bulbils are significant in the plant’s reproduction, as they can fall off and grow into new plants. The overall presentation of Coralroot is quite elegant, making it a beautiful addition to the environments where it naturally occurs.

    • To humans

      The Cardamine bulbifera, commonly known as Coralroot, is not typically known for being poisonous to humans. However, it is important to note that many plants can cause adverse reactions in some individuals due to allergies or sensitivities. Ingesting any part of unknown plants should generally be avoided due to the potential of unexpected toxicity.

    • To pets

      Cardamine bulbifera, known as Coralroot, is not widely recognized for being toxic to pets. However, the same cautions that apply to humans should be considered for pets. Not all plants' effects on pets are well documented, and there may be variability in how different animals react to certain plants. If a pet ingests Coralroot and shows signs of distress, such as vomiting, diarrhea, or changes in behavior, it is important to contact a veterinarian promptly. It is always best to err on the side of caution and prevent pets from ingesting plants that are not certified as safe for them.

  • water dropWater

    The Coralroot (the common name for Cardamine bulbifera) prefers consistently moist soil, without being waterlogged. Watering should be done when the top inch of soil feels dry to the touch, which typically means watering once a week. Depending on the size of the pot and the environmental conditions, this could range from 16 to 32 onzes of water each time. It's crucial to avoid over-watering, as this can lead to root rot. During the winter months, when the plant is dormant, reduce watering frequency.

  • sunLight

    Coralroot thrives in partially shaded conditions, mimicking its natural woodland habitat. It should be placed in a spot where it can receive dappled sunlight, away from direct and harsh sunlight which can damage its leaves. A north-facing or east-facing window, where the light is bright yet indirect, would be an ideal location for this plant.

  • thermometerTemperature

    Coralroot does well in average room temperatures between 60 and 75 degrees Fahrenheit. It can survive minor drops to about 50 degrees Fahrenheit, but should not be exposed to temperatures below that, as it can damage the plant. It's comfortable in the same temperature ranges typical for most indoor environments.

  • scissorsPruning

    Coralroot requires minimal pruning, primarily to remove any yellowed or dead foliage to maintain its appearance and health. This can be done as needed throughout the year. The best time for more thorough pruning is in the late winter or early spring before new growth begins, which can encourage bushier growth and rejuvenate an older plant.

    Coralroot Cardamine enjoys a well-draining soil mix with high organic content. The ideal soil pH for Coralroot Cardamine should be slightly acidic to neutral, ranging from 6.0 to 7.0. Mixtures with leaf mold or compost, perlite, and peat are beneficial for this woodland perennial.

  • plantRepotting

    Coralroot Cardamine does not require frequent repotting. It is typically repotted only when it has outgrown its current container, which may take several years. Repotting every 2-3 years should be sufficient.

    Coralroot Cardamine thrives in moderate to high humidity levels, ideally around 50-70%. It prefers a moist environment, much like its natural woodland habitat. Avoid placing it in overly dry conditions.

  • circleLife cycle

    Coralroot Cardamine, also known as Cardamine bulbifera, begins its life cycle as a dormant bulb, which sprouts and grows into a leafy shoot in the early spring. The leaves develop and the plant soon blooms, producing small, delicate purple or pink flowers typically between April and June. After pollination, which is often aided by insects, the plant produces seed pods that split open when mature to release the seeds. In addition to seed production, Coralroot Cardamine can also reproduce vegetatively through bulbils that form in the leaf axils, which can fall to the ground and grow into new plants. As the growing season ends, the above-ground part of the plant dies back, and the bulbs or bulbils enter a period of dormancy during the colder months. The cycle recommences the following spring when temperatures rise and the bulbs sprout anew.

      Spring to early summer

    • The most popular method of propagation for Coralroot (Cardamine bulbifera) involves the use of its unique bulbils, which are small bulb-like structures that form in the leaf axils. During late spring to early summer, these bulbils mature and can be collected. They should then be immediately planted in moist, fertile soil at a shallow depth, just enough to cover the bulbil, typically less than an inch (about 2.5 centimeters). In a suitable environment with partial shade, the bulbils will germinate and develop a root system, eventually growing into new plants. This method is very straightforward and does not require complex equipment or techniques, making it accessible for most gardeners. It's important not to let the bulbils dry out before planting, as this can decrease their viability.
