About Chilean rhubarb
Gunnera tinctoria, also known as Nalca or Giant Rhubarb, is a large perennial herbaceous plant native to Chile and Argentina. It is characterized by its enormous leaves, which can reach up to 2 meters in diameter, with a rough texture and an intense green color. It is ideal for creating a spectacular visual impact in large gardens, near ponds, or in humid and shady areas where its majesty can be fully appreciated.

Care tips
It requires a location with partial or full shade, as direct sun can scorch its large leaves. It needs constantly moist soil rich in organic matter, so watering should be abundant, especially in summer. Protect the plant from frost by covering the crown with its own dry leaves or straw during winter. A common mistake is planting it in dry or sun-exposed soils, which leads to poor growth and scorched leaves.
