Description

The spear thistle is perhaps the most likely candidate for the Scottish national emblem (5). It is a tall thistle, with a long tap-root(2). Young plants form rosettes of bristly leaves that have a downy upper surface; rosettes persist for around 1 year before flowering stems are produced (4). These flowering stems are cottony, deeply furrowed and have spiny 'wings', they support deeply lobed and spiny leaves (2). The large purple flower heads are 3-5 cm long and 2-5 cm across and are arranged in clusters (4).
