As you are all most likely aware (or were made aware of its presence last week when it arrived...) some severe storms rolled through much of south-central and southeastern Iowa last week.

Those tall plants with delicate white flowers popping up along roadsides and field edges may look harmless. They are not. Poison hemlock is a toxic plants in Missouri and every part of it is poisonous, whether green or dried. This plant spreads aggressively, with a single plant producing up to 38,000 seeds.

How to identify poison hemlock:
• Height: Can reach 6 feet or taller
• Stems: Smooth, hollow, hairless with distinctive purple blotches or streaks
• Leaves: Fern-like, finely divided, with a strong unpleasant odor when crushed
• Flowers: Small white flowers in umbrella-shaped clusters
• Growth cycle: Low rosette the first year, tall flowering plant the second year
• Poison hemlock is often confused with Queen Anne’s lace, but that plant is shorter, hairy and not toxic

How to get rid of it safely:
• Hand removal: Only for small infestations and with full protective clothing
• Mowing or tillage: Can help reduce spread
• Herbicides: Most effective in the early rosette stage before flowering

Safety tips:
• Wear gloves, long sleeves and eye protection when handling
• Avoid inhaling plant material during removal
• Never burn poison hemlock — inhalation can be dangerous
• If unsure, do not touch the plant
