Apparently hemlock is a BFD. Five or six leaves, ingested, will kill an adult. The roots and seeds are even more poisonous than the leaves. Even when dry and dead, the plant will remain highly toxic for THREE YEARS. So…here’s the question…are the weeds at the garden hemlock or some mimic?

Both google and our plant identification app indicate that this is Santa Maria, also known as Parthenium hysterophorus, and while it causes horrible things like a lack of tomato yield and contact dermatitis, it is not going to kill us. 🏅
