Questions, corrections or a better source? We would like to hear from you. Zonnebloemen.com is written by people, and reader feedback keeps the reference accurate.
The simplest way to reach us is by email. There is no contact form on this site — we keep the pages static and tracker-light, and a single email address is faster and more private for everyone.

What we would love to hear
- Corrections. If something on the site is wrong, out of date or unclear, tell us — ideally with the page address and what you think is off. Accuracy matters more to us than being right, and corrections are the quickest way the reference improves.
- Source suggestions. Know a more authoritative or more recent study, dataset, museum catalogue or book on the sunflower? Send it along. We list everything we rely on openly on the sources & method page and add to it regularly.
- Questions. Stuck on something about growing, biology or history that the site doesn't answer? Ask. Your question may well become the next page or a useful addition to an existing one — see, for example, the growing guide or the section on problems and diseases.
What this site is
Zonnebloemen.com is an independent, free, bilingual reference on the sunflower, Helianthus annuus. It is not a shop and does not sell seed or plants, so we cannot take orders — but we are glad to point you towards the right information. To learn more about who we are and how we work, see the about page.
We read every message and try to reply, though as a small project it can occasionally take a little while. Thank you for helping keep the reference reliable.
