Plant ID Week 1: Weeds

The very first full Plant ID practical session was on weeds. Here are some images, with links to a plethora of information from Garden Organic at the UK.

Ranunculus repens, creeping buttercup.
More information here.

Red deadnettle information here, coltsfoot here.
 P. major here.

Poa annua, more on which herewith.

A Sonchus sp and Senecio jacobea,
 the common ragwort.

Stinging nettle, Urtica dioica.

Broad-leaved dock, Rumex obtusifolius. The other common
dock is the curled dock, R. crispus.
Dock seeds can survive in soil for 50 years. Fifty. Years.

Pineappleweed, Matricaria discoidea. Does
indeed sort of smell of pineapple.

Not chickweed (Stellaria media). Knotweed, Polygonum sp.

Information here.

Spear thistle, detail.

The common mouse-ear, Cerastium fontanum

My "favourite", hah, weed is now couch grass, Elymus repens. I used to consider the creeping buttercup ("sprinting buttercup", my mother-in-law says) my nemesis, but have since acquired a garden half of which was completely overrun by couch. I don't expect ever to win that war, but have so far managed to not lose the battles...

Here it is, in all its unassuming glory:

Looks deceptively meek, doesn't it. Come spring, it'll EAT GLYPHOSATE.
