About Prickly saltwort
Salsola tragus, commonly known as "Russian thistle" or "winged-fruit Russian thistle," is an annual herbaceous plant characterized by its rounded, branched shape, often forming tumbleweeds that disperse with the wind. Its leaves are small, alternate, and linear to subulate, sometimes with a spiny tip. This plant is ideal for dry climate gardens or for adding a rustic, naturalistic touch, although its tendency to disperse makes it an invasive species in many regions.
Native range
Eurasia, from the Mediterranean to East Asia.
Care tips
It requires full sun for optimal growth and is extremely drought-tolerant, so watering should be minimal once established. It prefers well-drained soils, even sandy or poor ones, and is not demanding in terms of nutrients. A common mistake is overwatering or planting it in moist soils, which can lead to root rot; this plant thrives in neglected conditions.
