rock jasmine


The Androsace studiosorum, commonly known as rock jasmine, is a charming alpine plant notable for its rosette-forming habit. The leaves of rock jasmine are small, narrow, and lance-shaped, often covered with fine, soft hairs that give them a velvety texture. These leaves are predominantly green, sometimes with a hint of gray due to the fine hairs. The flowers of rock jasmine are its most distinguished feature. They bloom in clusters on top of short stems that rise slightly above the foliage. Each flower is delicate, with five petals that are usually pale pink to white in color. The center of the flower often has a contrasting yellow or red eye, which adds to its ornamental appeal. The overall growth form of rock jasmine is compact, with the rosettes and flowering stems creating a dense, cushion-like appearance. This plant thrives in rock gardens, crevices, and alpine troughs where it can mimic its natural mountainous habitat. Despite its delicate looks, rock jasmine is a hardy plant that can withstand harsh conditions typically found at high altitudes.

  • water dropWater

    Rock jasmine requires consistent moisture, so water it when the top inch of soil feels dry, which often equates to once or twice a week. Depending on the environment's humidity and temperature, it may need more or less frequent watering. As a general rule, aim for about one ounce of water per square foot of soil each week during the growing season. Adjustments should be made for rainfall and changes in environmental conditions to prevent overwatering.

  • sunLight

    Rock jasmine thrives in full to partial sunlight. The ideal spot for this alpine plant is a location where it can receive morning sunlight and some afternoon shade, especially in hotter climates. Protecting the plant from the intense midday sun will help to keep the delicate flowers from getting scorched.

  • thermometerTemperature

    Rock jasmine does best in cool to moderate temperatures and can survive in temperatures ranging from just above freezing to about 75 degrees Fahrenheit. The ideal temperature range for this plant is between 50 and 70 degrees Fahrenheit. Extreme heat or cold is detrimental to the plant, so it should be protected from frost and high summer temperatures.

  • scissorsPruning

    Rock jasmine benefits from occasional pruning to remove dead or damaged foliage and to maintain its compact shape. Pruning is best done in the early spring before the new growth begins. Light pruning can also be carried out after flowering to encourage further blooms and prevent the plant from getting leggy.

  • circleLife cycle

    Androsace studiosorum, commonly known as Rock Jasmine, begins its life cycle when seeds germinate in cool, moist conditions, often in alpine or subalpine environments. Seedlings establish a root system and form a basal rosette of leaves during their initial growth phase. As the plant matures, it produces flower stalks with clusters of small white or pink flowers, typically blooming in the late spring to early summer. Following pollination, often by insects, the flowers develop into small capsules containing numerous tiny seeds. These seeds are dispersed by wind or water, or through attachment to animal fur, leading to the colonization of new areas. The plant may endure through the harsh alpine winters by dying back to the ground and re-emerging from its perennial rootstock when conditions improve in spring.

      Spring to Summer

    • Propogation: Androsace studiosorum, commonly known as Rock Jasmine, is best propagated through seed sowing. This should ideally take place in late winter to early spring. To propagate Rock Jasmine, evenly distribute the tiny seeds on the surface of a well-drained seed starting mix, but do not cover them as they require light for germination. The pot should be placed in a bright location but out of direct sunlight. To maintain a consistent level of moisture, cover the pot with a plastic wrap or a glass pane. The seeds typically germinate at temperatures between 65 to 75 degrees Fahrenheit (18 to 24 degrees Celsius). Seedlings can be transplanted into individual pots once they are large enough to handle and grown on until they are ready to plant out in their final positions.
