Latest wacko garden plan

So I've been thinking about the beautiful Zephirine Drouhin climbing rose that Martha grows and am considering the following. How about a rose arbor framing the cutting garden on the side of the house? Yes, the entrance might be much grander than what follows, but so be it. Once I take out the ailing dogwood it could work. Then, this article in Garden Rant makes me think that I might as well try growing asparagus along the side farthest from the fence, which, like most of my garden, reads as partial shade. Seize the day and go forth!
