The yellow, candle-like flower spikes of Great Mullein can reach up to two metres in height, making this an impressive plant of dry and grassy ground including gardens, waste ground and roadside verges. It is a biennial, spending its first year as a rosette of furry leaves and producing its flowers in its second year between June and August.
How to identify
The grey-green, oval, leaves of Great Mullein are covered in woolly hairs and appear in whorls around the tall stems. The flower spike appears at the top of the stem - the flowers themselves are small, but they form dense, yellow clusters around the spike.
