Using a small bookshelf turned outward and a curtain, why not create a closet in a nook or behind a door? Making sure to anchor the bookcase to the wall for stability, you could mount a hanging rod across the allotted space and disguise it with a curtain. If the bookcase is not sturdy enough to attach the hanging rack to, simply add a wall-mounted rod, like this one from Improvements.
Regrow roses!!! "My neighbor has a row of roses, which he took as cuttings. I asked how he took them. He simply plunges the cuttings into the ground. But his secret of success is the humble potato! Before planting cuttings, he pushes the bottom end into a small potato, which he believes keeps the cuttings moist as they develop roots. It sounds crazy, but his row of allotment roses is proof it works." (quote from link)
