sooby said:I don't think so unless you or a neighbour had bought seeds maybe? It's not native and not very hardy. Was it growing there last year or just appeared this year?
sooby said:Since Iberis umbellata and Iberis amara occur (introduced) in New England I would think it's more likely one of those. Iberis umbellata appears to be sold as a "wildflower". I think Iberis gibraltarica is more unlikely.
sooby said:They can vary, such as this mixture of Iberis umbellata.
GoBotany has a key for Iberis. If it doesn't fit any of these then it may be worth looking at another species but these three would be the most likely in that area if it occurred without having been seeded on purpose. There's not enough of the plant visible in your picture to follow the key but you may be able to do it with the plant in person:
