This flower, Coreopsis lanceolata, comes up every year and is beautiful. It is very successful at propagating and spreads quickly. I like this in a blooming flower, but not in a weed. It has literally taken over.
I had a bit of a search for the actual name: Lance leaved coreopsis.
About 5 years ago a neighbour gave us a clump of a few flowers. We planted it in our front yard that gets full sun. It has grown and expanded every year, irregardless of a hard or mild winter. While the roses are temperamental and need care, the coreopsis needs nothing.
