Description:

Hypericum androsaemum, commonly known as sweet-amber or tutsan, is a plant in the genus Hypericum native to open woods and hillsides in Eurasia. It is a perennial shrub reaching up to 1.5 m in height.

In New Zealand, tutsan was recognised as a pasture weed as early as 1955. Biological control methods were investigated about 60 years ago. In 2008, Landcare Research will begin investigating the feasibility of a biological control.

It is also a declared species in Western Australia and Victoria, where it occurs in the wettest regions such as the Otway Ranges and the karri forests. It does not usually invade improved pastures, but is common in run-down pastures and in native forests. When established, tutsan can be dangerous because it is very difficult to remove and is very unpalatable to both native and introduced herbivores.
