I'd add that, where I live but probably in a number of areas of the US, even a plowed and wildflower-seeded tract of land will basically turn into mixed forest over time--which has actually happened with a lot of former farmland in New England. Which is fine to some degree. I moved into an old farmhouse 25 years ago and let a section out towards the road basically regrow into forest which has fairly tall trees at this point. But you probably don't want that all the way up to the house for fire and other reasons.

(I keep a fairly small lawn and the rest--other than the forest break between me and the road--gets cut by a tractor once a year.)
