The results also suggest that there is a choice on Asteraceae members on family level and especially a choice on the genera Onopordum, Echinops L, Carduus L, Centaurea
iberica Trev.ex Spreng, Conyza bonarensis (L.) Cronquist, Hertia intermedia Boiss, Echinops griffithianus Boiss, Seriphidium quettense (Podlech) Ling, Bull, Cousinia heterophylla Boiss, Lactuca persica Boiss, Pulicaria angustifolia DC and Sonchus asper L.

, which are exotic in Southamerica may be considered indicators of anthropic environments.
The seasonal plants put on display included dragon flowers in various colours, chrysanthemum, marigold, pansy and species belonging to petunia, Centaurea
