Named after its fruit, which is large and prickly, it also bears large white or purple, bindweed-like flowers. It's native to warmer regions of North- and Central America, and is not common in the UK but is more prevalent in hot summers. It often arrives into gardens via contaminated bird seed.

Thorn apple seeds remain viable for many years, so seedlings may appear on newly disturbed ground. However, the plants are easy to remove – simply pull them out or hoe the seedlings. If you pull out the plants before they set seed then simply compost them, but if they have set seed you will need to dispose of them by burning or burying them deeper than 60cm in the soil, to prevent the seeds from germinating. Always wear gloves when handling thorn apple, and wash your hands thoroughly afterwards.
