Hemlock water-dropwort
These numerous white umbellifers (umbrella-shaped flower clusters) are poisonous, but their flower-heads attract a wide variety of insects. It shouldn’t be confused with wild parsley as it’s highly poisonous if eaten. In fact, it’s the most poisonous plant in the UK, although some animals can eat it.
