Can you confirm that you meant opposite or alternate leaves on the Euphorbia maculata?

Prostrate knotweed has alternate leaves, while spurge has opposite leaves.

Prostrate knotweed has alternate leaves while spurge is opposite. I accidentally wrote 'alternate' in the spurge figure caption. It was updated as soon as we detected the mistake. Thanks for noticing and asking.

I have noticed that my sheep absolutely love the prostrate knotweed. Do you know anything about the feed value of it or what it contains that might be so tasty to them? They will often eat it before other grasses that look more appetizing. Thanks

Hi Meadow, I don't know much about knotweed and it's palatability or toxicity. I did find this website from TAMU suggesting that the species can cause some issues to animals that feed on it (although the toxic agent is unknown) https://rangeplants.tamu.edu/plant/knotweed/. NCSU suggests that oxalate accumulation can be a problem https://herbarium.ncsu.edu/poisonous/families.htm. My suggestion is to reach out to a UC Rangeland or Livestock advisor for more information regarding animal feeding.
