Fact sheet
Description: 

Helianthus is a genus of plants that are all native to North America. There are about 50 different species and they include many different sunflowers and the Jerusalem artichoke. Our specimen arrived with a small collection of Victorian thin sections and is labelled simply as Helianthus.

The sample had been stained to highlight the internal features. We applied a further colour change to give it back a more natural appearance.
