Poison Hemlock

looks like: tall (6-10 ft) plant with feathery leaves, white umbrella-shaped flower clusters, purple-spotted stems (this is the key ID feature)

where: roadsides, ditches, abandoned lots, riverbanks across north america and europe — extremely common and spreading

toxic part: everything, especially seeds and roots

what happens: coniine causes ascending paralysis — first weak legs, then chest paralysis, then death by respiratory failure while fully conscious

timeline: symptoms in 30 min - 3 hours, death in 4-8 hours

common mistake: foragers confusing with wild carrot (Queen Anne's Lace) or wild parsnip. look for the PURPLE SPOTS on stem and the mousy smell when crushed

historical note: famously the poison that killed socrates

emergency: poison control + ER, ventilator support critical
