How we can help
Something is wrong
A care range, hardiness zone, toxicity note or botanical name that conflicts with a reliable source. These are handled before anything else.
Where did this come from?
Ask which source a specific figure came from, how a range was worked out, or when a page was last updated.
Working together
Extension services, nurseries, researchers and publishers who want to share data or discuss licensing.
Before you write about a plant detail
Our sourcing rules, toxicity policy and corrections process are set out in full, and answer most data questions.
