Sandwort (Arenaria montana)

Sandwort Plant Features

If you aren't familiar with sandwort you're missing out on one of the prettiest little ground covers for sunny or partially sunny locations. Growing just 6 inches tall, this ground hugger produces a tight, moss-like mat of shiny dark green foliage that can spread 12 inches wide. In the early spring, sandwort is smothered in masses of cheery white flowers. Use sandwort in rock gardens, slopes, or in containers. Sandwort flowers attract butterflies. The plants are deer resistant. Hardy from zones 4-8.

Sandwort Growing Instructions

Sandwort grows best in full sun and moist, well-drained soil. Avoid planting sandwort in spots where the soil stays wet all the time or in heavy clay soil. Once established, this spring-blooming groundcover is relatively drought-tolerant, but it does best when watered regularly in times of drought. Because of this, sandwort makes an effective groundcover along rock walls or between flagstones in paths and patios.

You don't need to prune or remove the faded flowers from sandwort to keep it blooming; once planted, this sun-loving perennial is pretty easy to care for. 

In good soil conditions, you don't usually need to fertilize sandwort, but if you wish to do so, use any general-purpose garden fertilizer in spring and early summer. 

Sandwort is not recommended for human or animal consumption.
