Fern asparagus (Asparagus setaceus) has the laciest leaf in the world.

And it is the easiest plant in the world to grow. Funny, though, you cannot find it at the nursery.
Instead, you have to wait for it to pop up in your garden. In truth, it is a weed. But if you are a
flower arranger and you have fern asparagus growing somewhere in your garden, you will add a few sprigs of it every time you pick irises, daffodils, calla lilies, birds-of-paradise, or whatever else you put into a vase.
