Here's a great gift idea: seed bombs, specifically designed for your region of the country, and a wooden slingshot for delivering them to the earth.
Seedbombs are now available specific to your region of the country to ensure that you're only disseminating native flowers to your region:
Seedbombs are made from a mixture of clay, compost, and seeds. [They] are becoming an increasingly popular means of transforming the forgotten spaces of the urban environment. Seedbombs contain hundreds of native seeds. Once thrown, seedbombs have the ability to lay dormant for up to a year. Once they receive a little sun and water, they'll sprout in just a few days and begin to grow.
Utilizing the slingshot allows you to fling them into hard to reach niches of your city. Get a seedbomb slingshot for $3.50 or a 10-pack of seedbombs with a slingshot for $10 at GreenAid's Commonstudio shop.
