Rock Jasmine Androsace sempervivoides
ABOUT
Androsace sempervivoides, commonly known as the Rock Jasmine, is an alpine flowering plant noted for its interesting form and beautiful floral display. It has a low-growing, mat-forming habit, typically creating dense cushions of greenery. The leaves are small, numerous, and may be slightly hairy, often forming rosettes. They possess a succulent appearance, reminiscent of some stonecrop varieties, contributing to the plant's overall lush, textured look. The charm of the Rock Jasmine lies in its blossoms, each consisting of multiple small flowers clumped together at the top of short flower stalks.

WaterRock Jasmine should be watered regularly yet cautiously, as it prefers moist but not waterlogged soil. During the growing season, water the plant when the top inch of soil feels dry to the touch, typically every 5 to 7 days. Use enough water to moisten the soil throughout the pot, but be sure to allow any excess to drain away. Depending on the pot size, this may be approximately 8-16 ounces of water per week. In winter, reduce watering frequency to prevent root rot as the plant enters dormancy.
LightRock Jasmine thrives in bright, indirect light. It should be placed in a spot where it can receive a few hours of morning sun followed by dappled or partial shade for the rest of the day. Avoid intense, direct afternoon sunlight as it can scorch the leaves.
TemperatureRock Jasmine performs well in cool to moderate temperatures, ideally between 50 and 68 degrees Fahrenheit. However, it can tolerate temperatures as low as 40 degrees Fahrenheit and as high as 75 degrees Fahrenheit. Avoid exposing the plant to temperatures outside this range to prevent stress and damage.
PruningPrune Rock Jasmine to maintain its shape and encourage bushier growth. The best time for pruning is in early spring, just after the plant finishes blooming. Deadheading spent flowers and trimming back overly long or leggy stems can be done as needed throughout the growing season to keep the plant looking tidy.
CleaningAs needed
SoilThe best soil mix for Androsace sempervivoides, also known as Rock Jasmine, should be well-draining with a mix of loam, sand, and gritty material like pumice or fine gravel. The soil pH should be slightly acidic to neutral, ranging between 6.0 and 7.5, to emulate their native alpine habitats.
RepottingRock Jasmine should be repotted every 2 to 3 years to refresh the soil and accommodate root growth. It's best to repot in spring just before the onset of the growing season, being careful not to disturb the roots excessively.
Humidity & MistingRock Jasmine thrives in moderate to low humidity environments typical of its native alpine regions. It can tolerate dry air but should be protected from overly humid conditions, which can lead to fungal issues.

Life cycleAndrosace sempervivoides, commonly known as Rock Jasmine, initiates its life cycle when the seeds germinate in a suitable environment, typically in alpine or subalpine regions. The seedlings emerge and develop into a rosette form, characteristic of many alpine plants. As it grows, Rock Jasmine establishes a deep root system that allows it to absorb water and nutrients from the rocky soils it often inhabits. The plant reaches maturity and produces small, attractive pink or white flowers during spring or early summer, which are pollinated by insects. Following pollination, the flowers develop into fruit that contain seeds, completing the reproductive stage. The plant endures winter dormancy and resumes its growth cycle in the spring, often living for several years given its perennial nature.
PropogationPropogation time
Spring-summer
Propogation: Androsace sempervivoides, commonly knownas Rock Jasmine, is commonly propagated by seed. The best time for sowing the seeds is late winter or early spring, in well-drained soil mix, covering the seeds lightly with fine grit or compost. It's essential to keep the soil moist but not waterlogged. After sowing, the seed tray should be placed in a cold frame or cool greenhouse, as germination may be slow and could take several weeks to occur. Once seedlings are large enough to handle, they should be pricked out into individual pots and grown on in cooler conditions until large enough to plant out in their final positions. This method is attractive for its simplicity and effectiveness in producing new plants that are true to the parent species.
