Product Description
Acanthocalycium ferrarii is a rare, globular to short cylindrical cactus native to the northwestern provinces of Argentina, where it thrives in dry, rocky grasslands. It features distinct vertical ribs, each lined with white-woolly areoles and armed with yellowish to gray spines, often gently curved. During the warm months, it produces striking funnel-shaped flowers in hues of yellow, white, or pink, contrasting beautifully with its armored body. This elegant species is prized for its compact form, bold spination, and colorful floral display.
