Field Notes

I am happy because it looks like there is no purple loostrife in our area. We smelled fall in the air. We saw geese in the pond and a dry area with lots of weeds and trees.

We looked for blade shaped leaves 6-10 cm long covered in tiny soft hairs. The leaves are arranged oppositely or in whorls of 3. What we found was a leaf arranged in alternating patterns.

The petals of the flowers we saw were purple just like the loostrife, and they also had 5 petal.

The deciding factor that we did not have it was the fact that the stem was not square, nor did it have the little hairs.

Good job with the ID.

Good job with the ID. Noticing how plants are different from eachother is the first step to identification.

Keep your eyes open! Great job.

Purple plus!

Great supporting evidence. I'm glad to see that you looked closely at the leaves and stem, and weren't swayed by the flower similarities!
