Why does my gum taste like salad?

I grabbed lunch at Umami Burger with friend Julie (see the wine tasting post below) at the hipster hangout epicenter, Space 15 Twenty. Space 15 Twenty is a shopping center with an  Urban Outfitters, Free People,  an art gallery and screenings of Spike Jonze films.   Right outside Umami, we noticed a Seedbomb "gumball machine."  For fifty cents you can purchase a ball of seeds of regional flowers and engage in a green terror campaign by bombing areas that need plant life the most: dirt patches, parking lots, abandoned lots...and giant hipster shopping centers.
