Buy a flower pot that you really like and use Rust-Oleum Specialty 10 oz. Glow in the Dark Spray paint to paint the pot. During the day, the paint will absorb the sunlight and at night the pots will glow.
I had to share this idea that my mom shared with me from Facebook!
After reading reviews on the paint…make sure you do at least 2 or 3 coats and place in direct sunlight.
Also Glonation (http://glonation.com/bright-time-glow-paint.php) claim to have the best and most pigmented glow in the dark paint. They say the glow lasts for hours and is very bright. The prices are very reasonable too.
