Eriocaulon setaceum

---

​Eriocaulon "setaceum'"varieties are found throughout the tropical regions of the world and several spp are described: Australia (E. setaceum), Asia (E. intermedium), Africa (E. bifistulosum) and S. America (E. melanocephalum). Currently these spp are lumped together as E. setaceum.
In Australia there are two varieties of Eriocaulon setaceum available. Eriocaulon setaceum "Aussie" is larger in crown width and stem thickness and bushier than the second variety Eriocaulon setaceum "type 1".
Eriocaulon setaceum "Aussie" is the more difficult of the two varieties to grow and propagate. This variety can be propagated via seed germination or by new plantlets developing from the flower head (viviparity).
Eriocaulon setaceum "type 1" is of unknown origin and most likely an exotic variety. This variety propagates vegetatively by splitting of the plant at the growing tip into two new plants.
