Furcaria, also known as Furcraea, is a genus of succulent plants characterized by large, strap-like leaves and tall flower spikes. They are native to tropical and subtropical regions of Central and South America. These plants are known for their ability to form clumps of stemless, star-shaped rosettes in dry, rocky habitats. Some species, like Furcraea foetida, are cultivated for their fiber, which is used to make bagging and other coarse fabrics. 

Here's a more detailed description:

Leaves:

Growth:

Most Furcraea species are stemless, but some larger plants may develop a short, trunk-like stem.

They are found in dry, rocky environments and can tolerate drought conditions. 

Common Names:

Furcraea foetida is commonly known as Mauritius hemp, green-aloe, or giant cabuya. 

Other Names:

The genus Furcraea is also known as Fourcroya Spreng, Funium P.Willemet, and Roezlia Laurentius. 

Cultivation:

Furcraea plants are cultivated both as ornamental plants and for their fiber. They are known for their drought tolerance and ability to thrive in warm climates. 

Variegated Forms:

Some varieties, like Furcraea foetida 'Mediopicta', have variegated leaves with green and creamy-yellow stripes.
