Plant of the Day (January 16th, 2012) - Plantago major L. agg.

Plantago major L. from the Plantaginaceae is today's “Plant of the Day”. It's a very common species with many English and German names like “Common Plantain” in English or “Breitwegerich” in German. Other typical German names are e. g. “Wegtritt”, “Großer Wegerich” or “Wegeblatt”.

P. major - habitus

It's a small perennial plant, which can reach heights between 5 and 60 centimetres (2 to 23.5 inches). The crude, egg-shaped leaves are located in a rosette. They have a long petiole (3 to 12 centimetres or 1.2 to 4.7 inches) and between 5 and 9 leaf veins on the back. Their margin is even or a little bit wavy.

The inflorescences are terminal spikes, which are located at the end of a long, leafless stalk. Each spike has a length between 8 and 20 centimetres (3.1 to 7.9 inches). The small, green flowers are very inconspicuous. Flowering time is between June and October. The ripe fruits are small, green capsules with 6-10 seed inside. They are very sticky, so the seeds can be distributed by sticking on wheels, shoes or paws.

P. major - habitus

P. major is native to Europe, but can also be found as Neophyte in many other parts of the World like North America. It is very resistant to pressure and other mechanic influences and also salt, so it grows on paths, trails and even streets and public places, because it's no problem for P. major, if people walk over it . In North America, this species is also called “White man foot prints” by the Indians, because it was brought to their land by European settlers and started to grow at the paths of the White man treks.
