About Alternanthera pungens
Alternanthera pungens, commonly known as Khakiweed, is a perennial creeping plant belonging to the Amaranthaceae family. It is characterized by its grayish-green to reddish leaves and small whitish flowers in axillary spikes, developing tough spines in the leaf axils as it matures. It is ideal for rock gardens, dry areas, or as a groundcover in places where other plants struggle, although it should be handled with caution due to its spines.
Native range
Tropical and subtropical South America
Care tips
This plant thrives in full sun for optimal growth and tolerates drought well once established, requiring sporadic watering. It adapts to a wide range of soils, as long as they are well-drained, including poor and sandy ones. A common mistake is overwatering, as it is very susceptible to root rot in waterlogged soils. Given its invasive nature in some regions, it is recommended to control its spread.
