2019 March Unknown Plant ID

Asked April 2, 2019, 5:37 AM EDT

Hi, I have several plants I've been as yet unable to identify. Photos attached. First one looks like dead nettle but more furry and purple stems, and more tightly clustered and moundlike. Second looks a bit like a crucifer, little clusters of four-petal white flowers. The third is a low furry matt former, starts with tiny clumps.

The first one could be early Henbit- we can't make out the hairs. More here:http://extension.umd.edu/hgic/topics/henbit Check the stems. If it were Purple Dead Nettle, the stems will be square.

It resembles the first year growth of the biennial invasive Garlic mustard, too. Crush and smell the leaves. (The first year is just a low mound, but the second year it shoots up and flowers. More info here: http://extension.umd.edu/hgic/topics/garlic-mustard)

The second one looks like Field pennycress (Thlaspi arvense).


And the third one looks like Mouseear chickweed, which is a perennial.

Indeed, first one was garlic mustard. Now I'm seeing it all over the neighborhood. At least mine is no more. Thank you! The other two: thank you as well!

If I may, one more March plant is puzzling me. See photo:

Looks like prickly lettuce (Lactuca serriola). Here's a good photo of the same stage in development: https://www.invasive.org/weedcd/pdfs/wgw/garlicmustard.pdf

Incidentally, there are some garlic mustard seedlings coming up, too.

We hope you will share the info about garlic mustard with your neighbors, as this invasive can be miserable to get rid of once it develops a seed bank. They will thank you in the long run.

Thank you very much, that's very helpful! I'm learning! The other stuff sprouting in the photo by the way was some dead nettle. Both it and the Lactuca s. are gone! Thanks again!
