Plectranthus thyrsoideus, commonly known as the Candle Plant, is a visually striking plant that bears distinctive features. This plant typically has a lush, bushy appearance, characterized by its rich green foliage. The leaves are usually soft to the touch and have a slightly scalloped edge, with a texture that can be described as velvety. The foliage sometimes exhibits subtle variegation, with lighter veins against a darker green background, providing a textured and vibrant look. At certain times of the year, the Candle Plant produces vibrant inflorescences which consist of numerous small, tubular flowers that are arranged in a tall, cone-like cluster. These flowers are often purplish, blue, or lavender in color, adding a pop of color to the green canvas of the leaves. As the common name suggests, the floral display can be reminiscent of a lit candle, due to the shape and manner in which the flowers are presented above the foliage on slender, upright stems. The texture, color, and arrangement of the leaves along the stems contribute to the overall plush appearance of the Candle Plant. The stems themselves can be semi-succulent, adding to the plant's ability to thrive in various conditions. When the plant is not blooming, its dense and intricate foliage still makes it a favorite choice for creating a lush, green backdrop in gardens or indoor spaces. Its visual appeal is further enhanced when it is allowed to fill out and create a soft, mounded shape, overflowing with greenery.

  • water dropWater

    The candlestick plant (Plectranthus thyrsoideus) prefers consistently moist soil, so it's important to maintain a regular watering schedule. Water the candlestick plant once a week, providing enough water to soak the soil thoroughly, which might be approximately 16 to 24 ounces for a medium-sized pot. During the growing season in spring and summer, you may need to water more frequently, especially if the plant is outdoors in warmer conditions. Always check the top inch of the soil before watering; if it feels dry, it's time to water. Decrease watering in the winter months, allowing the soil to dry out slightly more between watering sessions.

  • sunLight

    The candlestick plant thrives in bright, indirect light for optimal growth. It is best positioned in a spot where it can receive plenty of light without being exposed to harsh, direct sunlight, which can scorch the leaves. A north or east-facing window would provide ideal lighting conditions for the candlestick plant, offering it the gentle light it needs to flourish.

  • thermometerTemperature

    The candlestick plant does best in warm conditions, ideally between 60-75 degrees Fahrenheit. It can tolerate a minimum temperature of 50 degrees Fahrenheit but should not be exposed to temperatures below this as it may cause damage to the plant. Maintaining a consistent temperature within this range will promote healthy growth and prevent stress to the plant.

  • scissorsPruning

    Prune the candlestick plant to encourage fuller growth and to maintain its desired shape. Light pruning can be done at any time of the year, but the best time for heavier pruning is in the early spring before new growth begins. Cut back any leggy stems or dead foliage, and shape the plant as preferred. Pruning every few months will keep the candlestick plant looking its best.

  • circleLife cycle

    Plectranthus thyrsoideus, commonly known as Candlestick Plectranthus, begins its life cycle as a seed that germinates in warm, moist soil conditions, usually in spring or early summer. After germination, the seedling emerges, developing roots and a set of true leaves as it enters the vegetative growth stage, where it continues to grow and mature, developing a bushy structure. During its active growth period, Candlestick Plectranthus requires adequate water, sunlight, and nutrition to reach maturity. As it enters the flowering stage, typically in late summer to fall, it produces inflorescences composed of small, tubular flowers that are attractive to pollinators. After pollination, the plant sets seed, which can be dispersed by various means, ensuring the propagation of the next generation. Eventually, as the growing season ends or in response to environmental stress, the plant enters senescence, where growth diminishes, and the plant may die back, especially in regions where it is not hardy; however, it can regrow from rootstock or cuttings if conditions permit.

      Spring to summer

    • Plectranthus thyrsoideus, commonly known as Cabo Plectranthus, is a plant that is typically propagated through stem cuttings. To propagate through this method, a healthy stem cutting of about 4 to 6 inches (approximately 10 to 15 centimeters) long is taken from a mature plant. It is best done in the late spring or early summer when the plant is actively growing. The lower leaves are removed, and the cut end may be dipped in rooting hormone to encourage root growth. The stem is then placed in a well-draining potting mix, ensuring that the node where the leaves were removed is buried. The pot should be kept in a warm, humid environment with indirect light, and the soil should be kept moist but not waterlogged. Roots typically develop in a few weeks, after which the new plant can be gradually acclimated to less humid conditions and eventually moved to its permanent location.
