About Prickly saltwort
Salsola kali, commonly known as prickly saltwort or Russian thistle (stekend loogkruid and zacht loogkruid in Dutch), is an annual halophytic plant that forms globular, spiny clumps. Its branched stems and succulent leaves make it resilient to arid and saline conditions, and its spherical shape at maturity turns it into a 'tumbleweed' that disperses its seeds with the wind. It is ideal for xeriscape or coastal gardens, where its hardiness and unique form can be appreciated.
Native range
Europe, Asia, and North Africa
Care tips
This plant thrives in full sun and tolerates poor, sandy, or saline soils, with no need for fertilization. Watering should be minimal once established, as it is extremely drought-tolerant and overwatering will harm it. It does not require special substrate, adapting well to challenging conditions. The common mistake to avoid is overwatering, which can lead to root rot.
