Notocactus Leninghausii

The Notocactus Leninghausii, also known by its scientific name Parodia leninghausii, is a remarkable cactus native to Brazil. Appreciated for its long golden spines and columnar growth, it brings a bright touch to any collection. Easy to grow with proper care, it appeals to both enthusiasts and advanced beginners.

Its light green cylindrical body is marked by numerous fine ribs (up to 30), well defined, lined with white areoles bearing fine, soft golden spines. This spiny covering gives the plant a silky, shiny appearance, especially highlighted in full sun. As it ages, the Notocactus Leninghausii can reach up to 1 meter in height, particularly when grown in the ground in warm climates.

Flowering is one of its main attractions: in summer, it produces magnificent yellow funnel-shaped flowers at the top of the plant. These flowers, although short-lived, appear in large numbers on mature specimens.
