In cultivation, snow weed prefers full sun to partial shade and soil that is sandy or rocky with good drainage. It is a low-maintenance plant that requires minimal watering once established.

Uses of Snow Weed

Snow weed has several uses ranging from ornamental to medicinal. In gardens, snow weed is often grown for its aesthetic appeal, adding a touch of silver-green color to rock gardens, borders, and alpine plantings. The plant’s low-growing habit and tolerance to cold make it a popular choice for winter landscapes.
