Hello, This plant is the Texas Thistle ( Cirsium texanum ) beleive or not it is of the sunflower family. It is amazing how many plants belong to this family including asters and so many others. This plant can get 5 or 6 feet tall and at leat 4 feet wide, so it takes up some room.
It likes full sun. Normally it only lasts until June or July so it gives you a chance to plant something else in it's place for the rest of the season. This is a native, my book says that it is a biennial, but in my experience it has been an annual, although it does self seed, and I never have to plant seed.
