I have three or four old cell phones sitting in the bottom drawer of my desk (along with roughly 20 cables and wires I have absolutely zero need for), so I’m relieved that today’s rain means that the Golden Triangle Business Improvement District’s “Flowers for Phones” promotion has been moved to tomorrow.

The concept is pretty straightforward: take your old, busted cell phone to either Farragut Square Park (Connecticut Ave. and K Street) or Golden Triangle Park (21st Street/M Street/New Hampshire Ave.) tomorrow between 11 a.m. and 2 p.m., hand it over to the BID to be recycled, and you’ll get a lovely potted daffodil, just like the one you see at right (and we see we’re not the only ones who got guilted into posting about this).

The BID estimates there are 500 million used cell phones across the country with the potential to cause environmental harm, so they’re offering this easy way to get yours safely recycled. All makes and models of mobile phones, pagers, and PDAs will be accepted, along with any batteries, chargers and accessories.

Nice bonus: all those turning in old cell phones will be entered to win a number of prizes from businesses within the BID (see full list).
