Giant Rhubarb
Amazing, architectural foliage for a moist spot in the garden. These awesome, textured leaves can grow up to 2m! They unfurl their gorgeousness on spiny stems of up to 2.5m. The happier it is, the bigger the leaves will be.
In summer, little, red green flowers open in conical panicles of a metre or more open and are followed by ornamental, round red-green fruits. The branches from it are over 10cm and covered in seeds.
They hail from Cool to Temperate mountains in Brazil/Columbia and won’t endure humidity or too much heat. Water well, those leaves are big and like to be hydrated. Well watered it will also establish faster and look its best sooner (they will take a couple of years to reach potential). It needs good light but not too much afternoon sun, you want them to stretch towards it and grow big so they can capture it. Bog gardens, pond edges or dams are great spots for this beauty.
Plant into humus rich, moist soil in a spot that doesn’t get too many drying winds. It becomes frost tolerant, but while it establishes a winter mulch is best. Protect new growth from slugs and snails. They will gradually settle into a winter dormancy as the frosts settle in.
