Brazil: Gnaphalium purpureum thrives in all types of soil, particularly heavy soils as long as they are not too dry. This species tolerates a certain amount of salinity.
China: G. purpureum grows in waste fields at low elevations.
Comoros: Gnaphalium purpureum is absent.
Madagascar: G. purpureum is a recently introduced weed which can be found on the central highlands and at medium altitude. It grows especially in the cool season in vegetable crops in the lowlands on the banks of irrigation canals.
Mauritius: ruderal species present in various crops, in fallows and wastelands, in the humid and very humid areas of the island.
Reunion: It is a pantropical weed, present in various crops, in fallows and wastelands. It is ubiquitous, present in all types of soil from sea level to 1200 m above sea level and whatever the level of rainfall. In Reunion, it is present in both the West Coast and the East Coast, even in Cilaos.
Seychelles: absent.

Local harmfulness
Comoros: Gnaphalium purpureum is absent.
Madagascar: Gnaphalium purpureum is a fairly common weed of vegetable crops, but rarely troublesome.
Mauritius: A weed of little importance in sugarcane, having very low harmfulness.
Reunion: This species is present in 22% of the cultivated plots of all cultures. It is especially common in lentil crops. In vegetable cultivation and lentils, its covering may reach 50-70 %. If it is not controlled at the beginning of culture, it becomes an important agronomic constraint, with a high potential of invasion.
Seychelles: absent.
