Most cultivated plants with showy flowers are entomophilous and do not cause pollen allergies.

However, because of its quick growth, clinging vines and broad leaves, it can overwhelm and pull down cultivated plants including shrubs and small trees.

These cultivated plants lack seed dormancy because of generations of selective pressure by plant breeders and gardeners that grew and kept plants that lacked dormancy.

They discourage wanton destruction of nature including of wild and cultivated plants.
