Prickly cucumber vine spotted and confirmed in Portland, Maine
iNaturalist: awright21
Citizen Science
Prickly cucumber can scramble over shrubs and garden edges with surprising speed in a single season, so knowing it's established in your neighborhood helps you catch it early before it smothers native plantings.
Someone in Portland, Maine spotted a plant called prickly cucumber growing along Shepherd Lane and submitted a photo to iNaturalist, where experts confirmed the ID. Prickly cucumber is a fast-growing native vine with spiny, balloon-like fruits that can take over disturbed areas and fence lines quickly. Sightings like this help build a map of where the plant is showing up and how its range may be shifting.
