Opuntia are cacti with segmented, often flattened stems, varied shapes and sizes, and colourful flowers.
Opuntia have stems divided into segments, often flattened, in a wide range of shapes and sizes. Colourful flowers complement their distinctive silhouette, from small plants to shrubby forms.
Alongside visible spines, many have glochids, tiny bristles that detach easily. Avoid direct skin contact; adult size and cold tolerance vary by species. Explore Tephrocactus.
