Notes

This Australian ornamental shrub was recently reported for the first time in the wild from the Canary Islands (Gran Canaria and Tenerife) ( Verloove 2017). Since then, it was repeatedly observed again, especially in Gran Canaria and a future, local naturalisation seems inevitable. Callistemon viminalis produces large quantities of very tiny seeds that are easily wind-dispersed. Wherever germination conditions are suitable, the species can reproduce from seed, for instance, in barrancos close to urbanisations.

In recent years, it was recorded again in two new localities in Tenerife.
