Gunnera tinctoria
1 gallon pot
 
Gunnera tinctoria, commonly called giant rhubarb or Chilean rhubarb, is a herbaceous, rhizomatous perennial native to stream banks, forest margins near wetlands, and moist bluffs in Chile and Argentina.  Mature plants can reach up to 6' tall with a similar spread. The 3' wide, coarsely lobed leaves have prominent venation and are armed with sharp spines. Tiny, dull red flowers are densely packed on 3' tall inflorescences. The main bloom period occurs in summer, but can vary based on climate. The flowers are followed by small, round, orange-red fruits.
