chrysanthemum 'Ropure'


The Chrysanthemum 'Ropure', commonly referred to as mum or chrysanthemum, is a flowering plant that catches the eye with its flamboyant bloom characteristics. It boasts a dense array of petals, often presenting a lush, full appearance that can be quite visually striking. Typically, the flowers of the 'Ropure' variety display a vibrant color palette, which may include shades ranging from bright yellows to deep reds, although the specific hue can vary widely based on the cultivar. Each bloom consists of numerous small petals that radiate outward from the center, creating a dome or cushion-like shape commonly associated with chrysanthemums. The petals might exhibit variegation or gradation in color, adding depth and complexity to the visual display. These blooms are known for their longevity and are often used in ornamental displays and floral arrangements for their lasting quality. The foliage of the 'Ropure' chrysanthemum is also attractive, typically presenting a deep green color. The leaves are likely to be lobed or deeply serrated, offering textural contrast to the softness of the flowers. The plant’s overall growth habit tends to be well-branched and bushy, providing a robust backdrop that further accentuates the beauty of the flowers during their peak blooming period.

  • water dropWater

    Water the garden mum moderately, ensuring the soil is evenly moist but not soggy. During active growth, especially in hot, dry weather, check the moisture level of the soil every few days, and water thoroughly as needed, which may be about once a week. You may need to provide about 1 to 1.5 gallons of water per plant each week, adjusting based on rainfall and temperature. Avoid overhead watering to reduce the risk of foliar diseases, and instead water at the base of the plant early in the day to allow foliage to dry. During the winter, reduce watering to match the plant's reduced needs, and only water when the top inch of soil feels dry to the touch.

  • sunLight

    Garden mums thrive in full sunlight, so place them in a location where they will receive at least 6 hours of direct sunlight daily. They can tolerate partial shade, but flowering may be reduced in less than optimal light conditions. Avoid overly shaded areas, as this can lead to leggy growth and poor blooming.

  • thermometerTemperature

    Garden mums prefer a temperate climate with temperatures ranging from 50 to 75 degrees Fahrenheit for optimal growth. They can survive minimum temperatures down to about 32 degrees Fahrenheit but are not tolerant of extreme heat or frost. Keep them in conditions where temperatures don't exceed the mid-80s Fahrenheit to prevent heat stress.

  • scissorsPruning

    Prune garden mums in early spring when new growth begins and throughout the growing season to encourage bushiness and more blooms. Pinch back the tips of stems by 1 to 2 inches at 3- to 4-week intervals, stopping the pinching process by mid-summer, around July 15th to allow flower buds to form. Prune away any dead or damaged stems as needed for the health of the plant.

  • bambooSoil

    Chrysanthemums require well-draining soil enriched with organic matter, with a pH range of 6.0 to 7.0. An ideal soil mix can be made by combining two parts of garden soil, one part peat moss, and one part perlite or coarse sand to ensure proper drainage and aeration.

  • plantRepotting

    Mums should be repotted every one to two years to replenish nutrients and prevent root crowding. It is best to repot mums in the spring just before the new growth begins.

  • water dropsHumidity & Misting

    Mums prefer a moderate humidity level, around 40-60%. They can tolerate lower humidity levels but thrive best when the humidity is kept consistent and not allowed to drop too low.

  • circleLife cycle

    Chrysanthemum 'Ropure', commonly known as Hardy Mum, begins its life cycle when the seeds germinate in warm, well-drained soil typically in early spring. The seedlings emerge and grow into young plants, developing a bushy formation with deeply lobed leaves. As the plants mature through the spring and summer, they continue to grow and may be pruned to encourage a more compact bush with more flowers. Bud initiation occurs as the days shorten and the weather cools, usually by late summer or early fall, leading to a profusion of blooms that can last until the first hard frost. After blooming, the plant enters a period of dormancy through the winter, where it may die back to the ground depending on the climate. With the return of warmer temperatures in spring, the Hardy Mum can exhibit new growth from surviving root systems or overwintered cuttings, repeating its annual life cycle.

      Spring-Early Summer

    • The Chrysanthemum, commonly known as 'mum', is a plant that can be easily propagated through the division of its root clumps, typically during the spring when new growth appears. This is the most popular method of propagation for 'mums'. To propagate by division, dig up the entire plant as the new shoots reach about 1 to 2 inches tall, being careful not to damage the young shoots. Gently separate the clumps of roots by hand or with a sharp knife, ensuring each division has at least one shoot and a portion of the root system intact. Replant the divisions immediately in well-prepared soil with ample organic matter to encourage healthy new growth, spacing them about 18 to 24 inches apart (45 to 60 cm). Regular watering and a light fertilizer application can help establish the new plants. This method allows gardeners to rapidly increase their 'mum' collection or rejuvenate older plants by removing the tired center and replanting the vigorous outer portions.
