About Eryngo
Eryngium plantagineum, commonly known as "long eryngium" or "pampa thistle", is a perennial plant from the Apiaceae family native to South America, valued for its blue-silver foliage and distinctive cone-shaped flowers. Its spiny inflorescences, emerging from rigid, sharp bracts, add unique texture and architectural appeal to xeriscape gardens and rockeries. It is ideal for adding visual interest to low-maintenance landscapes or as a cut flower in dried arrangements.
Native range
South America: Argentina, Uruguay, Brazil, and Paraguay.
Care tips
This plant thrives in full sun, requiring at least 6 hours of direct sunlight daily for optimal growth and abundant flowering. It prefers well-drained soils, even poor or sandy ones, and is very drought-tolerant once established, so watering should be sparse. Avoid excessive soil moisture, especially in winter, as it can lead to root rot. It does not tolerate transplanting once established, so it is best to plant it in its final location when young.
