Xanthorrhoea johnsonii is predominantly an outcrossing species according to Borsboom (2005). This means that X. johnsonii cross polinates with other species to create variants of itself, creating a mixed mating system. When populations of grasstrees are small the likelihood of self-polination is higher. The general number to look for in breeding species is about 500 […]
This may depend on the type of Xanthorrhoea species. According to Borsboom (2005) Xanthorrhoea australis seeds can remain viable even after 5 years of appropriate storage with temperature and light having significant influence on seed germination. For Meyrik Farm, we have a tremendous amount of seeds but still have to experiment with how to germinate […]
Cinnamon Fungus (Phytophthora cinnomonia) The Cinnamon Fungus has the ability to rot the roots of grasstrees causing them to die. It's impact on the Xanthorrhoea Johnsonii variety is unknown and seems to be more significant for species outside of Queensland, Australia, although further investigation is required according to Borsboom (2005). Beetles Beetles often sit on […]
