Gardeners in the UK are being alerted to the dangers of three-cornered garlic, an invasive plant that resembles snowdrops and wild garlic. This non-native bulb can reproduce rapidly, making it difficult to control once established. Under the Wildlife and Countryside Act 1981, it is illegal to allow this plant to spread in the wild, and homeowners must take measures to contain it. Richard Barker, a horticultural expert, highlights that the seeds attract ants, which help in dispersing them. The plant also produces underground bulbils that can break off during weeding, further aiding its spread. Although not banned from sale, planting it in the wild is an offense. Jennifer Holmes from Environment Controls emphasizes that the plant should not be composted or placed in green waste bins, as even small fragments can regrow. Professional removal, involving careful excavation or herbicide treatment, is recommended to manage this invasive species effectively.
