This is an interesting plant known by a variety of names.
Among them Queen Anne’s Lace, Bird’s Nest, Lace Flower, and Wild Carrot.
Though confused at times with other plants like Hemlock which is highly toxic if ingested the Queen Anne can be identified by the single purple flower in the center.
Some refer to this flower as red, and others say it isn’t always present, I’ve yet to personally see one with a red center as opposed to purple but taking their word for it.
Overall I’d say it’s a hardy plant requiring little attention – it’s also a plant that can become invasive, so better not to plant in proximity to any area you’d prefer for it not to be.
