chrysanthemum 'Grandchild'


The Chrysanthemum 'Grandchild' is a particularly striking variety of mums known for its vibrant and showy flowers. This plant typically features lush, green foliage with leaves that are deeply lobed and have a somewhat coarse texture. The leaves form a dense canopy, creating an attractive backdrop for the blossoms. The flowers are the most notable aspect of the 'Grandchild' mum, blooming in a profusion of color that can add a bright spot to any garden. The blooms themselves are composed of numerous petals that radiate outwards from the center, creating a full and round appearance. They have a pompom-like shape, known for their fluffy and soft consistency, which gives them a striking and pleasing aesthetic. Petals may come in a variety of shades depending on the specific cultivar, ranging from white to various shades of yellow, pink, purple, and red, often with a gradient or varying intensities of color. The center of the flowers, where the petals meet, is typically a deeper or contrasting hue, giving the blooms a two-toned effect that further enhances their visual appeal. In summary, the Chrysanthemum 'Grandchild' is celebrated for its rich, vividly colored flowers that can bring a splash of brightness to any setting. The abundant, cushiony blossoms are set against a backdrop of dark green, lobed foliage, making the plant a favorite among gardeners looking to add some fall interest to their landscapes.

As needed
  • water dropWater

    Mums, including the Chrysanthemum 'Grandchild', prefer evenly moist soil, so it's important to water them regularly but ensure the soil is not waterlogged. Water them deeply about once a week with 1 gallon of water per plant, allowing the water to seep into the ground rather than just wetting the surface. During hot, dry spells, you might need to water them more frequently to maintain soil moisture. Reduce the frequency of watering once the flowers have died back and the plant is dormant, but do not allow the soil to completely dry out.

  • sunLight

    Mums thrive best in full sun conditions where they can receive at least 6 hours of direct sunlight each day. The ideal spot for a Chrysanthemum 'Grandchild' would be a south-facing garden bed or a location that receives ample morning and early afternoon light. Avoid placing them in deep shade since insufficient light can lead to fewer blooms and a leggy growth habit.

  • thermometerTemperature

    The Chrysanthemum 'Grandchild' prefers temperatures ranging from 60 to 70 degrees Fahrenheit during the day and between 55 to 60 degrees Fahrenheit at night. They can tolerate a minimum temperature of 32 degrees Fahrenheit but are at risk of damage from frost. To encourage blooming, mums require a period of cooler temperatures between 50 to 60 degrees Fahrenheit.

  • scissorsPruning

    Pruning mums, such as the Chrysanthemum 'Grandchild', encourages a bushier growth and more blooms. Pinch back the tips of the stems by about an inch when they are 6 inches tall, which usually occurs in late spring. Repeat this process every 2 to 3 weeks until midsummer to keep the plant compact and to stimulate more flowering buds. The best time for the final pruning is by July 4th to ensure they bloom in the fall.

  • broomCleaning

    As needed

  • bambooSoil

    The best soil mix for mums, including Chrysanthemum 'Grandchild', should be well-draining and fertile, with a pH around 6.5 to 6.7. A mix of loamy garden soil, peat, and perlite or sand in equal parts is ideal, ensuring good aeration and moisture retention while avoiding waterlogging.

  • plantRepotting

    Mums like the Chrysanthemum 'Grandchild' generally need repotting every one to two years or when they outgrow their current container. They should be repotted in the spring before the onset of active growth.

  • water dropsHumidity & Misting

    Mums, such as the Chrysanthemum 'Grandchild', prefer moderate ambient humidity levels, around 40-60%. They can tolerate some fluctuation in humidity but should not be subjected to extremely dry conditions for prolonged periods.

  • circleLife cycle

    Chrysanthemum 'Grandchild' (21c), commonly known as Hardy Mum or Garden Mum, begins its life cycle when the seeds germinate in late spring after the last frost. The seedlings soon develop into young plants with a dense foliage of deeply lobed leaves. By mid-summer, these plants enter a vegetative growth stage, focusing on developing strong stems and leaves to prepare for flowering. As the days shorten towards the end of summer, the Hardy Mum enters the budding stage, which ultimately leads to its famous profuse blooming period in late summer to fall. During this stage, the plant displays a vibrant array of colorful flowers, which, if properly deadheaded, can last until the first hard frost. After flowering, the plant goes into dormancy during the winter, with the roots surviving underground; in spring, the cycle begins anew as new growth emerges.

    • Propogation time

      Spring-Early Summer

    • Propogation: The Chrysanthemum 'Grandchild', commonly known as mums, is most commonly propagated through vegetative cuttings. This method is favored for its ability to reproduce the same qualities as the parent plant. To propagate mums by cuttings, one would typically take 2 to 6 inch-long (5 to 15 cm) stem cuttings from the parent plant in spring when the plant is producing new growth. Each cutting should have several sets of leaves and is snipped just below a leaf node, where the concentration of growth hormones is highest. The cut end is often dipped in rooting hormone powder to encourage root development and then planted in a moist soilless potting mix. The cuttings are then kept in a warm, brightly lit area out of direct sunlight until they root, usually within a few weeks. Once roots have developed, the new plants can be transplanted to individual pots or directly into the garden.
