scentless mayweed


The plant commonly known as scentless chamomile or scentless mayweed has a delicate and wispy appearance. It is characterized by its branching stems that bear finely dissected leaves, which are feathery in texture and green in color. The plant displays numerous daisy-like flowers, each composed of a yellow disk at the center and white ray florets surrounding it, creating a classic wildflower look. These flowers are usually conspicuous, with a flat and open form, inviting to various pollinating insects. The entire plant is known for its lack of strong aroma, which distinguishes it from other similar-looking plants that tend to have a noticeable fragrance. Scentless chamomile blooms during the warmer months and puts forth a profusion of flowers that can cover the plant, offering a soft visual appeal in the settings where it grows. Despite its name and lookalike appearance to the popular chamomile, it does not share the same aromatic properties or uses.

  • water dropWater

    Scentless mayweed, as Tripleurospermum inodorum is commonly known, should be watered moderately, ensuring that the soil is allowed to dry out between waterings to avoid over-saturation. During active growth periods in the spring and summer months, it typically requires watering once every one to two weeks. Provide about 1 inch of water at each watering, which equates to roughly 0.623 gallons per square foot. It is crucial to water the plant at the soil level to avoid wetting the foliage, which can lead to fungal diseases. During the dormant winter months, reduce the watering frequency as the plant's water requirements decrease.

  • sunLight

    Scentless mayweed thrives best in full sun conditions, where it can receive at least 6 hours of direct sunlight daily. The ideal spot for this plant would be an open area free from the shade of larger plants or structures that could block sunlight. While it can tolerate some light shade, excessive shade may lead to lanky growth and fewer flowers.

  • thermometerTemperature

    Scentless mayweed prefers temperate conditions and is hardy in a wide range of temperatures, from as low as 20°F to as high as 90°F. However, its ideal growing temperature is between 60°F and 75°F. It can survive light frosts, but prolonged exposure to temperatures below 20°F can be damaging or lethal to the plant.

  • scissorsPruning

    Pruning Scentless mayweed is often done to maintain its shape and encourage bushier growth. It should be pruned in the late winter or early spring before new growth begins. Remove any dead or damaged stems, and cut back the plant by about one-third to promote new growth. Pruning can be done annually or as needed to control its size and shape.

  • circleLife cycle

    The common name for Tripleurospermum inodorum is Scentless Mayweed or Scentless Chamomile. The plant begins its life cycle with the germination of seeds, typically in the spring, after which the seedlings establish themselves with a rosette of leaves at ground level. As the plant matures, it develops an erect stem and branching occurs, leading to the formation of further leaves and the characteristic finely dissected foliage. During the flowering stage in the summer months, Scentless Mayweed produces abundant daisy-like white flowers with yellow centers, which are pollinated by insects. After pollination, the flowers give way to seeds, which are then dispersed by wind, water, or animal movement. The plant is an annual or short-lived perennial and completes its life cycle within one or two growing seasons, after which the plant dies, leaving seeds to start the next generation.

  • sproutPropogation

    • Propogation time

      Spring to Summer

    • Propogation: The most popular method of propagation for the Tripleurospermum inodorum, commonly known as scentless chamomile, is by seed. This plant tends to self-seed prolifically and can easily do so in suitable conditions without much intervention. To cultivate intentionally, it is best to sow the seeds directly into the ground during the fall or early spring. The seeds require light to germinate, so they should be scattered on the surface of the soil and lightly pressed in rather than covered. It's important to keep the soil moist until germination occurs. Thin the seedlings to about 12 inches (approximately 30 centimeters) apart to provide enough space for the plants to mature.
