We stopped having a vegetable garden a few years ago, with just the two of us here we don't need it like we did when the kids were at home. And the last couple years we did have one the tomatoes and cucumbers and zucchini all had blight. So we decided to switch it over to a perennial flower garden, this will be the 4th or 5th year for it. I've been enjoying seeing everything coming back to life. I've got several different kinds of perennials including brown eyed Susan, bee balm, butterfly bushes, hostas, milkweed, shasta and banana daisies, cat mint, salvia, lavender, sage, coreopsis, hibiscus, and several others I can't even think of. We have a winding path going down the middle of the garden, with a wooden arbor at the beginning (with clematis on either side of it) and a decorative wire fence-like thing at the other end for the morning glories (plant those annually). Most of the garden is covered in black mulch, with red mulch in the pathway. The pathway is lined in brick, and the whole garden has brick all the way around as edging. I have several decorative things out there too like a gazing ball, garden gnome, shepherd's hooks with windchimes and bird feeders, etc.
The only things I'm doing to the garden this year is to pull up one of the two chive plants as I'm tired of all the volunteer chives popping up. We do have landscape fabric covering as much of the garden as possible but those little seeds still find their way into the smallest spaces that don't have fabric. I also want to refresh both the black mulch and red mulch. And maybe add 2-3 new plants sometime, if I find something on sale at Menard's or Home Depot that I'd like to add to the garden. I love finding inexpensive plants at the end of the season that come back and really thrive the next year.
Oh, I do plant a whole row of Zenias on the north side of the garden too, and randomly put in some begonias as well. And right now I have daffodils, muscari and some other spring flowers blooming.
I would really love a "she shed" at the end of the pathway, about 10'x10' with a porch on the front. Have a couple rockers on the porch, and then inside have a couple nice comfy chairs on one side and then a trundle bed set on the other. It would be a fun way to have a granddaughter sleepover.

Or just a place to hang out, relax, read, nap.

I think they are getting kind of popular, sort of like a man cave. I've been hearing more about them, and seeing them in magazines.
As for vegetables, we just buy what we want at the local farmer's market.
