Critterologist -- to your question -- Mobot (with the link above) is where I learned (just this morning) that Goldstrum doesn't come true from seed.

Everyone: I have two weeds I can't identify -- they each create huge impenetrable patches, choking anything in their way. I'd love to know what they are.

The first (photos 1 and 2) is only about 2-3" tall; it is almost a mini-shrub.

The second (photos 3 and 4) is 5-6" tall.

Among other things, I'd love to know if they are annual or perennial weeds,,,.
