I love the look of this vintage planter, used in the home of a Brooklyn couple. Of course, the effect wouldn't be the same if the pram itself wasn't such a great design, but luckily, it's not too hard to find a vintage pram if you're on the hunt for one.
Look for a vintage pram like this one on eBay, or if you're really lucky, find one in your grandmother's attic. Line the pram with heavy duty plastic before adding soil, to maintain the integrity of the pram itself. I'd choose low-water plants such as succulents or cacti for this planter, so you don't have to overload the pram with water. Cover with a layer of pebbles or volcanic rock to keep things tidy.
