Prickly Lettuce

Edith Prickly

Meet the Prickly Lettuce (Lactuca serriola).  I'm not sure if it bears any relationship to Edith Prickly; perhaps it's named for her.

According to the Wikipedia entry, prickly lettuce is the closest wild relative of cultivated lettuce, with pretty much world-wide distribution.  From this fact, I would deduce that it is another non-native to these here parts.

This is another case where I should have photographed more of the plant -- like getting the leaves.  After a bit of Googling around, I see that this plant also resembles another variety of wild lettuce.
