Rock rose 'Ben More'


The Helianthemum 'Ben More', more commonly known as rock rose, is a vibrant, flowering plant known for its showy appearance. It has a bushy, mounded form that produces a dense mat of small, grey-green leaves. These leaves are lance-shaped and slightly fuzzy to touch, providing a silvery look to the foliage. During its blooming season, the rock rose is adorned with a profusion of flowers. Each blossom is crepe-paper-like in texture, with five petals that create a cup or saucer-shaped flower. The 'Ben More' variety of rock rose typically boasts flamboyant, bright yellow flowers that are particularly eye-catching. At the center of each blossom, there is often a cluster of delicate stamens, which add to the ornamental appeal of the plant. These radiant yellow flowers stand out against the silvery foliage, creating a striking contrast that can brighten up any garden space. The rock rose blooms abundantly, and while individual flowers may be short-lived, the plant produces a succession of blooms which can provide color for a good part of the season. Due to its vibrant flowers and attractive foliage, the rock rose 'Ben More' is a popular choice for gardeners looking to add a splash of brightness to rockeries, borders, or as groundcover.

  • water dropWater

    Rock rose should be watered sparingly; the plant is drought-tolerant and prefers dry conditions once established. Initially, water young plants regularly to ensure a strong root system, about once a week, providing approximately 1 gallon of water per plant. After establishment, reduce watering frequency, only watering when the soil is dry several inches below the surface. Overwatering can lead to root rot, so it's crucial to allow the soil to dry out between watering sessions. During particularly hot or dry spells, weekly watering may be necessary, but always check the soil moisture first.

  • sunLight

    Rock rose thrives in full sunlight and should be placed in a location where it can receive at least 6 to 8 hours of direct sun daily. The plant is well-suited for south-facing slopes or garden spots that receive unfiltered sunshine most of the day. Avoid planting in areas with shade or partial sunlight, as this can impede bloom production and overall health of the rock rose.

  • thermometerTemperature

    Rock rose prefers warm climates and is hardy in a temperature range from 30 to 100 degrees Fahrenheit. However, for optimal growth, maintaining temperatures between 50 and 80 degrees Fahrenheit is ideal. While the rock rose can survive brief periods of colder temperatures, prolonged exposure to freezing conditions can damage or kill the plant.

  • scissorsPruning

    Prune rock rose early in the spring to maintain shape and encourage bushier growth. Cut back the previous year's growth by about one-third to promote fresh, healthy shoots and to enhance flowering. Pruning should be done annually, and the best time is when new buds begin to swell but before they open into full bloom. Pruning at this time helps ensure a profusion of flowers and a well-structured plant.

  • circleLife cycle

    The common name for Helianthemum 'Ben More' is the Rock Rose. This plant's life cycle begins with seed germination that typically occurs in spring, under favorable conditions of warmth and moisture. Following germination, it enters a vegetative growth phase in which leaves, stems, and roots develop. After becoming established, Rock Rose proceeds to a flowering stage during late spring to summer, producing showy flowers that attract pollinators. After fertilization, seeds are set, and once mature, they disperse to give rise to new plants. The plant then enters a period of dormancy during the colder months, reducing activity to survive winter, and the cycle resumes with the next growing season.

      Spring to Summer

    • The Helianthemum 'Ben More', commonly known as Rock Rose, is best propagated through semi-hardwood cuttings taken in late summer. To propagate Rock Rose using this method, select healthy, non-flowering shoots and cut segments approximately 4 to 6 inches (10 to 15 centimeters) in length. Make sure each cutting has several leaf nodes. Dip the base of the cutting in rooting hormone powder to promote root development. Then, insert the cuttings into a pot filled with a well-draining potting mix, such as a mixture of peat and perlite. Water the cuttings, and place the pot in a warm, bright location out of direct sunlight. Roots often form within a few weeks, after which the cuttings can be gently transplanted into individual pots or a suitable garden location.
