Sprout Pencils are plantable pencils. All aspects of the Sprout pencil are sustainable and non-toxic – from the biodegradable seed capsule to the 100% natural clay and graphite core and PEFC/FSC-certified wood. When the pencil is too short to write, simply turn it upside down and plant the stump. If you water it regularly, you'll see the pencil transform into a plant. Regardless of whether you choose Sprout pencils in colour or in grey, they are a joy to use. And when it’s time to stop writing and start planting, you’ll find it’s just as much fun to watch the seeds turn into plants. All Sprout seeds have been selected because they are easy to germinate. So you can enjoy vibrant flowers, fragrant herbs or fresh vegetables.
