Invasive Species
If you tend a shady garden bed or walk a wooded trail near town, this glossy-leaved vine is likely nearby, forming dense mats that choke out native wildflowers and tree seedlings before they get a chance to grow.
Someone walking along Nassau Street in Princeton, New Jersey noticed a patch of greater periwinkle, a low, trailing vine with shiny leaves and purple flowers, and logged it on iNaturalist. Other naturalists reviewed the photos and agreed on the identification, making it a confirmed, research-grade record of where this plant is growing in the area.
