The plant can reach 1.5m in height. It is also commonly known as the Bull Thistle, Spear Thistle or the Scotch Thistle.

It is common in cooler or more temperate climates, expect flowers from July to September.

It grows incredibly well in most soil types, especially newly sown turf, rough grass and waste ground. Reproduction is by seed.

It can be an invasive species in some parts and infestations can quickly increase in density, as it is not a desirable plant to grazing livestock and other animals. It can dominate vegetation.

A huge number of seeds can be produced by a single plant and they exist as long as a moisture source is available.
