Good intentions can grow into pesky problems in the landscape when invasive plants are selected. The reality is, many invasive species came to Kauai as ornamental plants. And, there aren’t a whole lot of restrictions on introducing new plants—so sometimes, things go awry.
There are some helpful resources to identify whether plants you’re considering for your Kauai property are invasive. The Hawaii Pacific Weed Risk Assessment (HPWRA) considers plants’ characteristics and the likelihood of it becoming invasive.
And, a site called Plant Pono is an outreach to educate home gardeners. Further, the Kauai Invasive Species Committee provides a list of early detection plants.
At No Ka Oi, there are five invasive plants we don’t like to find on the commercial properties we serve because their presence requires diligent management, the plants easily overtake other beautiful flowers and shrubs, and they can potentially attract damaging pests that you don’t want to find on your property.
