Giant Hogweed (Heracleum mantegazzianum): Giant hogweed contains sap that can cause severe skin irritation, blistering, and even scarring upon contact.
Bamboo (Bambusoideae spp.): While bamboo can add a tropical aesthetic to your garden, it has a tendency to spread rapidly and become invasive, making it difficult to control and potentially disrupting nearby ecosystems.
Morning Glory (Ipomoea spp.): Despite its attractive flowers, morning glory is known for its aggressive growth and ability to smother other plants.
English Ivy (Hedera helix): English ivy is prized for its lush, trailing foliage, but it can quickly become a nuisance when it spreads uncontrollably, climbing up trees and buildings and causing damage.
Purple Loosestrife (Lythrum salicaria): While purple loosestrife may seem beautiful with its tall spikes of purple flowers, it is highly invasive and can choke out native plants in wetland areas, disrupting local ecosystems.
Wisteria (Wisteria spp.): Wisteria's fragrant blooms may be captivating, but its vigorous growth habit and tendency to twine around structures can lead to structural damage if not properly maintained.
Oleander (Nerium oleander): All parts of the oleander plant are highly toxic if ingested, posing a risk to humans and pets.
Bishop's Weed (Aegopodium podagraria): Bishop's weed, also known as goutweed, is a fast-spreading ground cover that can quickly outcompete other plants in the garden.
