Argentine fleabane: Full Sun Plant
Conyza bonariensis
As an invasive species, Conyza bonariensis does not require conventional cultivation. It grows rapidly in poor and compacted soils, with a remarkable germination capacity under various conditions. Control is made difficult by resistance to multiple herbicides and the massive production of seeds (up to 800,000 per plant) dispersed by the wind. Optimal germination occurs between 20-30°C, requires light, and tolerates a pH range of 4 to 10.
