Perennial vine with twining stems from the Polygonaceae family, native to Central Asia, Western China, and Tibet. It naturally grows on rocky slopes, edges, and disturbed grounds, often in dry and sunny conditions.
Its vigor is exceptional: the woody stems at the base can cover several tens of square meters in a few seasons, winding around any available support or cascading in masses over slopes and walls. This behavior is precisely what the photographs strikingly illustrate, with the plant covering an entire cliff with a dense and continuous mantle.
The leaves are oval-cordate, bright green, deciduous. The flowers are tiny, cream-white to slightly pink, gathered in loose and abundant panicles that literally blanket the foliage at the time of flowering, emitting a sweet fragrance perceptible from a distance.
In its natural habitat, its flowering extends from July to September. In cultivation under a temperate climate, it blooms at the same dates, often until October.
Completely hardy, not demanding on soil type, it grows just as well in full sun as in partial shade. Its vigor makes it an effective tool for quickly covering large, hard-to-reach areas, slopes, walls, or fences, but it requires sufficient space and regular control to prevent it from invading neighboring plantings.
