About Sandbur
Cenchrus longispinus, sometimes referred to as 'Victorian Gin', is an annual grass native to North America, characterized by distinctive spiny spikelets that readily attach to surfaces. Its wild appearance and inflorescence shape can add a rustic or naturalistic touch to dry gardens or ornamental meadows, although its invasive nature and sharp spines limit its use in formal landscaping. It is often considered a weed due to its easy spread and the nuisance caused by its spines.
Native range
North and South America
Care tips
This plant thrives in full sun and is extremely drought-tolerant, so watering should be minimal once established. It adapts to a wide range of soils, including poor and sandy ones, as long as they have good drainage. A common mistake to avoid is cultivating it in high-traffic areas or where it might come into contact with people or pets, due to its sharp spines. Often considered a weed, its control is more important than its cultivation.
