chrysanthemum 'Robeam'


Chrysanthemum 'Robeam', commonly known as the hardy mum, features a dense display of vibrant, decorative flowers. The blossoms are noted for their rich, bronzy-red color, which adds a warm autumnal touch to the plant's appearance. Each flower is composed of numerous petals that are slightly curved and overlapping, creating a full and rounded overall shape. The centers of the flowers are typically darker, often showcasing hues that may deepen towards a burnt orange or brown tone, giving the blooms an eye-catching bicolor effect. The foliage of the hardy mum is a deep green, providing a lush backdrop for the bright flowers. The leaves are generally oblong with serrated edges and have a somewhat coarse texture. This plant has a mounding habit, with stems that branch out gracefully, draped with leaves and topped with the colorful flowers. The robust nature of the hardy mum allows it to be a prominent feature in gardens, often used for mass plantings, borders, or decorative pots for seasonal interest. It is prized for its lengthy blooming period, which can extend from late summer through the fall, offering a long-lasting splash of color when many other flowering plants have finished their display.

  • water dropWater

    Mums should be watered regularly to keep the soil consistently moist but not soggy. In general, water the chrysanthemum deeply once a week with about 1 gallon per plant, adjusting for rainfall and temperature variations. During hot or windy weather, they might need more frequent watering. Make sure to water at the base of the plant to avoid wetting the foliage, which can lead to disease. Reduce watering in the late fall as the plant goes dormant if you're in a cooler climate.

  • sunLight

    Chrysanthemums prefer full sun conditions with at least 6 hours of direct sunlight per day. Place them in a location where they can get an abundance of light without being shaded by larger plants or structures. However, in extremely hot climates, some afternoon shade can help prevent overheating.

  • thermometerTemperature

    Chrysanthemums thrive in temperatures between 60 and 70 degrees Fahrenheit but can tolerate a range from just above freezing to about 90 degrees Fahrenheit. However, they will not survive in temperatures below freezing without protection. The ideal growing conditions include cool nights and warm days.

  • scissorsPruning

    Pruning chrysanthemums helps maintain their shape and promotes denser growth. Pinch back the tips of young shoots in the spring and early summer to encourage branching. In late summer, stop pinching to allow flower buds to form. Prune away spent flowers and any dead or diseased branches as needed.

    As needed

  • bambooSoil

    Garden mums like 'Robeam' prefer well-draining soil with good fertility and a slightly acidic to neutral pH, typically between 6.5 and 6.7. To create the best soil mix, blend equal parts garden soil, peat moss or compost, and perlite or vermiculite to ensure drainage and aeration. Incorporating organic matter will also help retain moisture while providing nutrients.

  • plantRepotting

    Chrysanthemums, commonly known as garden mums, generally don't need frequent repotting. They should be repotted once they become root-bound or every 2 to 3 years. When repotting, choose a container that is slightly larger than the current one to allow for growth.

  • water dropsHumidity & Misting

    Garden mums like 'Robeam' are fairly adaptable but prefer moderate humidity levels. Average indoor humidity is usually sufficient, but they will thrive in a range of 40-60% humidity, which coincides with typical household levels. Avoid placing them in excessively dry or overly humid conditions to maintain plant health.

    The Chrysanthemum 'Robeam', commonly known as Hardy Garden Mum, begins its life as a seed or more commonly from a vegetative cutting. After planting, the cutting roots and the plant enters a vegetative growth phase, producing a bushy mound of foliage. As the plant matures and day length shortens, the mum initiates budding, typically in late summer. Following bud initiation, the flower buds develop and bloom into vibrant flowers, often in autumn. Post-bloom, if not deadheaded, the flowers may produce seeds. After flowering, the plant enters a period of dormancy during winter, with above-ground parts dying back and the plant surviving through its underground structures until the next growing season.

      Spring-early summer

    • The most popular method for propagating the Chrysanthemum 'Robeam', commonly known as the hardy garden mum, is through stem cuttings. This process typically begins in the spring when the plant is producing vigorous new growth. A gardener will select a healthy stem and make a cut 4 to 6 inches (about 10 to 15 cm) long, ensuring a few leaves remain on the cutting. The lower leaves are removed and the cut end is dipped in rooting hormone to stimulate root development. The cutting is then planted in a well-draining soil mix and kept in a warm, humid environment with indirect light until roots have formed, which usually takes about three to four weeks. Once rooted, the new plant can be transplanted to a larger pot or directly into the garden.
