chrysanthemum [Ernst]


The Chrysanthemum Ernst, commonly known as Mum or Chrysanthemum, boasts a stunning display of flowers that are often admired for their vivid and striking appearance. The bloom's petals are arranged in a unique and intricate pattern, radiating from the center of the flower head in a way that can resemble a pompom or a daisy, depending on the variety. The color palette of these flowers can range widely, with hues from soft pastels to bolder shades, including whites, yellows, pinks, and purples, adding to the plant's allure and versatility in gardens and floral arrangements. The leaves of the Chrysanthemum Ernst are equally appealing, typically deep green and possessing a lush, healthy sheen. The foliage contrasts nicely with the bright flowers, and the leaves are often deeply lobed with a somewhat jagged edge, adding texture and interest to the visual composition of the plant. The overall form of the Chrysanthemum Ernst is bushy and full, with a tendency to produce a profusion of bloom heads that create a dense, eye-catching display of color when in season. This makes them a favored choice for both gardeners and florists alike.

  • water dropWater

    Mums should be watered regularly, keeping the soil consistently moist but not waterlogged. A good rule of thumb for mums is to water them with about one gallon of water per week, but this can vary based on environmental conditions like heat and humidity. During hot, dry periods, they may need water more frequently, possibly every other day. Always water at the base of the plant to avoid wetting the foliage, which can lead to disease. It's best to water in the morning to allow any splashed leaves to dry out over the course of the day.

  • sunLight

    Mums thrive best in full sun conditions, which means they need at least six hours of direct sunlight each day. The ideal spot for a mum would be in an area that gets the morning sun and is possibly shaded from the more intense afternoon sun, especially in hot climates. However, they are versatile and can also tolerate partial shade, but flowering may not be as prolific.

  • thermometerTemperature

    Mums prefer moderate temperatures and can generally survive in temperatures ranging from 32°F to 90°F. The ideal temperature range for growing mums is between 60°F and 70°F. It's important to protect them from frost and extreme heat, as temperatures below freezing can kill the plant, and high heat can stress them.

  • scissorsPruning

    Pruning mums promotes a more compact plant with more blooms. Pinch or cut off the tips of the stems in late spring to early summer, when the plants are about 6 inches tall, repeating every few weeks until mid-July. Do not prune after this time as it can interfere with flower bud development. The best time for significant pruning is after the blooming cycle when you can cut back the old stems to ensure healthier growth for the next season.

    As needed

  • bambooSoil

    Mums prefer well-draining soil with plenty of organic matter. A mix of two parts garden soil to one part peat moss and one part perlite or sand is ideal. Target a soil pH between 6.0 to 6.7 for optimal growth.

  • plantRepotting

    Chrysanthemums, commonly known as mums, should be repotted every one to two years to replenish soil nutrients and to accommodate root growth. It's best to repot in the spring before the growing season begins.

  • water dropsHumidity & Misting

    Mums thrive in moderate humidity conditions, ideally between 40-60%. They can tolerate lower humidity levels, but consistently dry air can cause stress and leaf dessication.

  • circleLife cycle

    The Chrysanthemum 'Ernst' begins its life cycle as a seed, which upon germination develops into a seedling with a basic root system and initial leaves. As it enters the vegetative stage, the plant focuses on leaf and stem growth, eventually forming a bushy structure. During the budding phase, flower buds appear and gradually develop. These buds bloom into the characteristic flowers of the Chrysanthemum during the flowering stage, showcasing a display of colors and attracting pollinators. Following pollination, seeds are produced, completing the reproductive cycle. Finally, in many climates, the Chrysanthemum may enter a period of dormancy during colder months before resuming growth in the next season.

    • Propogation time

      Spring-Early Summer

    • Propogation: The most popular method of propagating the Chrysanthemum, commonly known as Mum, particularly the Chrysanthemum Ernst = 'Yoernst', is through cuttings. This process typically begins in the spring when the new growth is about 3 to 6 inches (7.5 to 15 centimeters) long. Gardeners select healthy, non-flowering shoots and cut them just below the leaf node. The lower leaves are removed, and the cut end may be dipped in rooting hormone to encourage root development. These cuttings are then inserted into a moist, sterile growing medium, such as a mix of peat and perlite. The environment is kept humid by covering the cuttings with a plastic dome or using a mist system, and within a few weeks, they should root successfully, ready to be transplanted to their final growing location. This method is favored for its simplicity and effectiveness, ensuring genetic uniformity among offspring.
