Crassula acinaciformis

Crassula acinaciformis, the giant crassula, is a large, usually monocarpic rosette succulent from summer-rainfall grassland and rocky slopes in north-eastern South Africa, Eswatini and Malawi. It forms a flat rosette of sword-shaped leaves and eventually a tall branched head of small white flowers, then dies after seeding.
