I suggested blurring the flowers because, even in their blurred state, it will be obvious what they are and the color of the flowers and their form/arrangement are what anchor the foreground, not the details of the petals themselves, etc. The bale, if blurred, will be more amorphous and not necessarily a recognizable element, even in a field of grass. If you keep everything in focus, the scene gets a little confusing.
The form of the bale is really nice - its isolation is also sort of serene and its existence amid the grass is nice context. The sharpness of the bale and the grass would emphasize the nice texture that each possesses. The composition as in the original photo, with the tree line cropped, would be balanced as well and the blurred flowers in the foreground would separate and give depth to the image. The purples and blues of the flowers also adds a nice complement to the golds and oranges of the bale and grass.
Reshoot it if it is not inconvenient - shoot in the late evening for a golden tone and stronger definition of form via shadows or early in the AM for a bluish tone and see what you get. If you want to compress the fore and back grounds together, shoot telephoto, if you want more separation, shoot wide. Do all of that fun stuff in-camera as you will go insane trying to mask the flowers from the grass/bale. Try shifting focus, first shooting the flowers in focus and blurring the bale/grass, and then shoot another image focusing on the bale and blurring the flowers, etc.
Go for it, it will be a good learning experience with a nice scene. Who knows, you may even get a Wyeth landscape out of it. Or you could just 69 the bale and shoot the flowers. Hehe.
Enjoy!
