I found this picture online once and while it's not something we can do just now, it's definitely something that would be really nice. It's a cutting garden, laid out in rows like a vegetable garden might be done. Very neat way to do it. You can have rows of veggies, why not rows of flowers?
We have plenty of space to do this of course, but the watering, until we are out there regularly, wouldn't be easy for something like this. Until then, we can keep it here on the blog to remind us what we want to do.
