Native or climate-suitable? They are not the same thing
A plant that copes with your future climate is not automatically good for your local ecology — or legal to plant.

Native status is a question of geography and ecological history. Climate suitability is a question of tolerance. Garden Forward keeps the two labels separate and never infers native status from climate similarity.
The ecological evidence supports weighting towards natives without treating everything else as worthless. The RHS's four-year Plants for Bugs field experiment at Wisley, using 36 plots of native, near-native northern-hemisphere and exotic southern-hemisphere planting, concluded that planting biased towards British natives — combined with dense vegetation and some bare soil — best supports invertebrates, while near-native and exotic plants still played a positive role, particularly for winter cover and extending the forage season.
The published pollinator results are more specific: total pollinator abundance was higher on native and near-native plots than exotic ones, hoverflies were most abundant on native plots, honeybees on near-native plots, and long-tongued bumblebees showed no difference between treatments. For context, RHS baseline data put an average UK garden at roughly 70% non-native and 30% native planting excluding lawn.
The legal side is separate again, and jurisdiction-specific. In Britain, section 14 of the Wildlife and Countryside Act 1981 makes it an offence to plant or cause to grow in the wild any plant listed in Schedule 9 Part II. In the United States, the Plant Protection Act defines a noxious weed by the injury it causes and USDA APHIS maintains a Federal Noxious Weed List under 7 CFR 360.200. In Australia there is no single national list: declarations sit with the states, such as Victoria's four categories under the Catchment and Land Protection Act 1994.
These regimes are not equivalent and should not be paraphrased as one rule. What they share is a practical consequence for this site: any species listed as invasive or restricted in your jurisdiction is excluded from our recommendations entirely, however well it would handle your climate.
