I am Kees Jan van Zwienen and I live in Hagestein in the province of Utrecht in the Netherlands. On this site I share pictures from various botanical trips around the world. You can also see my publications, explore my photographic collections of plants in cultivation or have a look at my allotment. It is also possible to see the plants and animals by family or group.
If you are looking for pics of a particular genus or species, use the search function instead, this is found at the top of this page.
I give presentations for horticultural and botanical societies on most of the botanical trips featured on this site, feel free to get in touch if you are looking for a speaker.
PS All pics are copyright, reproduction without permission is not allowed, but arrangements can usually be made if you get in touch using the 'comment' button.
