Leonotis nepetifolia (weed) (L.) R.Br. - (annual lion's ear)

This plant is native to tropical parts of Africa and western Asia, but has been introduced as an ornamental into other regions like the Americas and Australia. In some areas it is regarded as a weed of crops like cereals, soybeans or sugarcane. In Australia it is mainly considered an environmental weed that can form large stands, suppressing native flora.

The plant grows to a height of up to 2 m. It has egg-shaped, serrated leaves and spherical clusters of small orange flowers. Each flower produces a capsule with 4 seeds that disperse through water or human activities.
