shaggy rock jasmine


Androsace villosa, commonly known as hairy rock jasmine, is a perennial alpine plant known for its distinctive and attractive appearance. This plant typically forms low-growing rosettes comprised of spoon-shaped leaves. The foliage is often covered with a dense layer of fine hairs, which gives it a soft, velvet-like texture and can make the leaves appear silvery or grayish-green in color. During its blooming period, hairy rock jasmine produces charming flower clusters on short stems that rise just above the foliage. Each cluster is an umbrella-like array of several small flowers. The blossoms are usually of a delicate pink or white hue, with petals that may be adorned with a yellow to pinkish central eye, providing a lovely contrast against the greenery. The fine hairy coating on the leaves is not just ornamental; it serves a practical purpose too. It helps the plant conserve moisture and provides some protection against the intense sunlight and harsh conditions of the rocky alpine environments in which it thrives. Despite its tough nature and ability to withstand cold environments, hairy rock jasmine carries an air of alpine delicacy and charm that makes it a prized specimen for rock gardens or as part of a collection of mountain flora.

  • circleLife cycle

    Androsace villosa, also known as Hairy Rock Jasmine, begins its lifecycle with seed germination, occurring in well-drained, rocky soil, usually in alpine or subalpine habitats. The seeds develop into small rosettes, forming a basal cluster of oval to lanceolate leaves covered in dense hairs. In the following growing season, the plant flowers, producing pink to purple flowers with a yellow eye, arising on short stalks from the leaf rosette. After pollination, often by insects, the flowers develop into small capsules containing numerous seeds. These seeds are dispersed by wind or rain, initiating new cycles of growth. The plant may also spread vegetatively through offshoots from the parent plant, although the primary mode of reproduction is through seeds.

    • Propogation time

      Spring to summer

    • Propogation: Androsace villosa, commonly known as the hairy rock jasmine, is often propagated through the sowing of seeds. The optimal time for propagation by seeds is in spring when the risk of frost has passed, typically after the temperature consistently stays above 50 degrees Fahrenheit (10 degrees Celsius). The seeds can be sowed in a well-draining seed starting mix, lightly covering them with soil. They need to be kept moist and placed in a bright area but not in direct sunlight. Germination usually occurs within a few weeks, and once the seedlings have grown sufficiently and can handle being transplanted, they may be moved to their final growing location outdoors with appropriate spacing to accommodate growth.
