About Trailing Rock Jasmine
Androsace lanuginosa · also called Trailing rock jasmine, Woolly rock jasmine · flowering
Androsace lanuginosa is a trailing, mat-forming evergreen perennial from the rocky slopes of the Himalayas in northern India and Nepal, forming loose mats of silvery-hairy ovate leaves to 45 cm wide. It bears rounded umbels of lilac-pink flowers with a pale or greenish eye on short stems in mid-summer to early autumn, and is the most free-flowering and garden-amenable Androsace species, holding an RHS Award of Garden Merit. Unlike most high-alpine Androsace, it tolerates slightly better moisture but still requires sharp drainage and is best kept dry overhead in winter. Androsace is not listed by the ASPCA; as no confirmed pet-safety data exists, treat it as mildly toxic and keep away from pets.
Ideal humidity: Low to moderate
The watering schedule, season by season
Trailing Rock Jasmine flowers best on steady, even moisture — let it dry out hard and it drops buds; keep it soggy and the roots rot before it can bloom. The base rhythm for trailing rock jasmine is moderate; allow top 2 cm to dry between waterings, but the real interval moves with the season, the light and the pot — so treat the figures below as a starting point and always confirm with the plant itself.
- Spring & summer (active growth): Spring and summer (active growth and bloom): keep evenly moist, watering when the top 2-3 cm is dry — typically when the soil tells you it is time.
- Autumn (slowing down): Autumn: ease back as flowering finishes and growth slows; let it dry a little more between waterings.
- Winter (rest / dormancy): Winter / rest: water sparingly while it rests, then resume as new growth and buds appear.
Keep roots evenly moist during the growing season but never waterlogged; water at the base to avoid wetting the hairy foliage, and reduce significantly in winter.

How to tell trailing rock jasmine needs water
A calendar is the worst way to water trailing rock jasmine. Check the plant and the soil instead — for this species, look for these signals in order:
- The top 2-3 cm of soil is dry to the touch.
- Leaves or flower stems lose turgor and start to droop.
- Buds stall or the pot feels light.
The most reliable single check is the first one on that list. When two signals agree, water; when they disagree, wait a day and look again — under-watering trailing rock jasmine for a day is almost always safer than over-watering it.
Overwatering vs underwatering trailing rock jasmine
The two failure modes can look alike at a glance, so check the soil weight and wetness before you decide. For trailing rock jasmine specifically:
Signs you are overwatering
- Yellowing leaves, bud drop, and a heavy, constantly wet pot.
- Mushy stems or crown rot at soil level.
- Fungus gnats and a sour soil smell.
Signs you are underwatering
- Wilting, bud and flower drop, and crispy leaf edges.
- A faded, stressed look and a rootball that has pulled from the pot sides.
Erratic watering — bone dry then flooded — makes trailing rock jasmine drop its buds and flowers. Consistency through the budding period is what protects the display.
Water quality notes
Tap water is generally fine for trailing rock jasmine unless your water is very hard; rainwater is a safe default if leaf tips brown.
Seasonal and environmental adjusters
Every figure above shifts with the conditions in your home. For trailing rock jasmine, the levers that matter most are:
- A blooming plant in good light drinks faster than a resting one — shorten the interval during flowering.
- Brighter, warmer spots dry the pot faster; check before watering rather than fixing a date.
- Empty the saucer after every water so the roots are never sitting in run-off.
Pot choice is part of this too — work out the right size with the pot size calculator, since a pot that is too big stays wet long enough to rot the roots of trailing rock jasmine.
