An Iowa gardener has alerted the community about invasive plants being sold at local garden centers, urging caution when purchasing popular but harmful species like Japanese barberry, dame’s rocket, and Bradford pears.
These plants, despite their attractive flowers or growth habits, pose serious ecological threats by spreading aggressively and outcompeting native flora.
Japanese barberry is notorious for its dense growth and sharp thorns, and it also contributes to the spread of ticks. Dame’s rocket, often mistaken for native phlox, quickly overtakes garden spaces, while Bradford pears are weak trees with unpleasant-smelling flowers and inedible fruit.
The gardener recommends native alternatives such as native phlox, plums, and serviceberries, which offer beauty and ecological benefits without the invasive risks.
Invasive plants can devastate ecosystems and require extensive effort to remove once established. Despite these dangers, many nurseries continue to sell these species due to their popularity.
Gardeners are encouraged to choose native plants to support local biodiversity, reduce maintenance, and create healthy habitats for pollinators. The Iowa Department of Natural Resources provides guides to help identify and manage invasive species.
