About Common smilax
Smilax polyantha, commonly known as sarsaparilla, is a woody climbing plant native to South America. It is characterized by its thorny stems, leathery leaves, and reddish berries, making it attractive for vertical gardens, hedges, or covering pergolas, providing a wild and robust touch.

Care tips
It prefers full sun to partial shade for optimal development, though it tolerates partial shade. Watering should be regular, keeping the substrate moist but not waterlogged, especially in warm periods. It requires well-drained soil, rich in organic matter, and slightly acidic to neutral. A common mistake is not providing adequate support for its climbing growth, which can limit its development and aesthetic appeal.
