Gunnera Seeds - Flower Plant For Home Gardens
Quality Gunnera seeds for flower beds, borders, containers, and pollinator gardens.
Gunnera, commonly known as Giant Rhubarb, is a large perennial ornamental plant valued for its massive leaves and bold garden presence. The plant forms a clump of thick stems supporting very large, textured leaves that spread widely across the garden space. During the growing season, tall flower spikes emerge from the center of the plant carrying dense clusters of small flowers. Gunnera grows best in moist, fertile soil with partial to full sunlight and performs well near ponds, water gardens, or consistently moist garden beds.
