We New Yorkers feel lucky when we've got a sliver of balcony space, and we want to make the most of it — even if the area is only wide enough to accommodate a couple of window boxes. Here are 10 modern planters that attach to a balcony wall or fit over balustrades and railings.

1. The Steckling Cube by Rephorm is a basic modern container designed to fit over a balustrade with a maximum diameter of 60 mm. Sold through European retailer Connox, it's €39.
2. Made from recycled plastic water bottles, Wally Woolly Pockets, start at $39 and can be hung on a balcony railing or wall.
3. Chicago store Jayson Home & Garden sells some beautiful, simple Wall and Balcony Troughs, starting at $40. For more money, you can buy them pre-planted.
4. A prototype not yet in productino, Royer and Thirion's Modern Planter for Urban Balcony is a modular, contemporary design. The modules — made from sheet metal, rubber аnd plastic — hook over a balcony balustrade.
5. Another prototype, the Modular Small-Space Balcony by Christian Lessing combines a vertical rack with adjustable seats, tables surfaces, and planters.
6. Available through A Plus R in Los Angeles, the Greenbo Railing Balcony Planter ($28) is a simple, chic rail planter made from UV-protected, high-quality polypropylene.
7. Hanging Boskke Sky Planters are distributed internationally — in the US you can find them through Sprout Home, Velocity Art and Design, and various museum stores.
8. Sold through Anthropologie spinoff Terrain, the Harvest Garden ($268) is an attractive wall-mounted version of a vertical garden.
9. Generate Design sells the arty Haisui Planter, $45. Created by Nobuhiro Sato, the wall-hung design resembles a miniature manhole.
10. Online catalog company Gardener's Supply sells several basic railing planters for balconies — the 30-inch version shown above is priced at $35.
