dayflower Coelestis Group


The Commelina tuberosa, also known as Dayflower or Widow's Tears, is noted for its iconic blue flowers that resemble little three-petaled flags, two larger petals above with a smaller one below. The flowers boast a striking, vibrant blue hue which is often highlighted by a yellow center, giving them a cheerful, eye-catching appearance. These blooms cluster atop the lush, green foliage that is quite fleshy, characteristically reflecting light and appearing glossy. The leaves are narrow, elongated, and pointed, arranged in an alternating pattern on the stems, providing a dense, green backdrop that makes the flowers stand out even more. The stems are herbaceous, meaning they are not woody, and they tend to be succulent, which allows the plant to be relatively drought-tolerant. This verdant growth is accentuated with a delicate, almost succulent texture to the foliage, creating a soft, inviting aesthetic overall. Additionally, the flowers only open for a single day but are typically replaced by new blooms rapidly, ensuring a continuous display of color during the blooming season.

  • water dropWater

    The Dayflower should be watered regularly, ensuring the soil is kept moist but not waterlogged. During the growing season, water it once every week with approximately one gallon of water, adjusting for rainfall and temperature conditions. In hot, dry periods, you may need to water twice a week. During the dormant winter months, reduce watering to every other week or less, depending on the dryness of the soil. Always check the top inch of soil for dryness before watering to avoid overwatering.

  • sunLight

    Dayflowers thrive in bright, indirect sunlight. The ideal location would be in a spot where it receives morning sun and afternoon shade. However, it can also adapt to partial shade conditions, which means it should be fine if placed in a spot with filtered light throughout the day. Avoid exposing the plant to the harsh afternoon sun, especially in hot climates, as this can damage the leaves and flowers.

  • thermometerTemperature

    Dayflowers do best in temperatures ranging from 60 to 85 degrees Fahrenheit. They can survive minimum temperatures of around 40 degrees Fahrenheit, but frost can be harmful. Always protect the plant from extreme cold and avoid placing it in locations where temperatures could drop below the minimum threshold. The ideal temperature condition is a moderate one that does not fluctuate dramatically, mimicking its natural tropical habitat.

  • scissorsPruning

    Pruning Dayflowers encourages bushier growth and prevents them from becoming leggy. Prune the plant in early spring before new growth begins. Remove any dead or damaged stems, and cut back up to one-third of the plant to maintain its shape and size. Pruning can be done again in late summer if necessary to remove spent flowers and stimulate new blooms.

  • circleLife cycle

    Commelina tuberosa, commonly known as the Dayflower or tuberous wandering Jew, begins its life cycle as a seed, germinating in warm, moist soil where it rapidly develops roots and shoots. The seedling stage is characterized by the emergence of the first pair of true leaves which soon grow into a rosette form as the plant enters the vegetative stage. During the vegetative growth phase, the Dayflower produces thick, fleshy stems and additional leaves, all while developing a tuberous root system that allows it to store nutrients and water. As it matures, the Dayflower enters the flowering stage, typically in summer or early fall, where it produces clusters of vibrant blue or violet flowers that open for only a day. After pollination, the flowers develop into capsules containing seeds that, when mature, drop to the ground or are dispersed, thereby completing the reproductive stage. In colder climates, the plant may die back at the end of the growing season, but the tubers can remain dormant underground through winter, ready to sprout again with the return of favorable conditions, thus making the plant a perennial in some regions.

    • Propogation time

      Spring to summer

    • Propogation: The Commelina tuberosa Coelestis Group, commonly known as the Dayflower, is typically propagated by division. The best time to carry out this method is in the spring, just as new growth begins to emerge. To propagate by division, first carefully dig up the plant, ensuring to keep a good amount of soil around the roots. Then, using your hands or a sharp knife, separate the tubers, each with a portion of roots and shoots, ensuring that each divided piece has at least one eye or growth point. Replant the divisions at the same depth they were originally growing in well-drained soil and water them thoroughly. These new plantlets should start to establish quickly with the arrival of warmer weather, leading to a successful propagation.
