Tower mustard (Turritis glabra) is a perennial herb (perennial meaning they live for more than two years). It can grow up to a metre in height and is commonly found in light soils, often along roadsides. When in bloom, it offers small and delicate white or pale yellow flowers. Whilst it may not draw the eye amongst other vegetation, it is a fantastic food source for lots of bees.

It is fairly common around the world and is native to North Africa, Europe and Asia. However, it can also be found in other parts of the world where it has been introduced. Globally, tower mustard is not a species at risk.

However, in the UK it is a different story. This once widespread species can only be found in fewer than 35 sites in the country. Tower mustard is even listed as a priority species in the UK’s biodiversity action plan. We're fortunate that it can still be found locally in half a dozen sites around Kidderminster. To ensure a future for tower mustard, we really need to do our bit and start spreading some seeds.
