Shep's slur upon flower-kind has little to do with actual plants. It stems (no pun intended) from the 24th-century anarchist movement, the "Angry Flowers," which grew (again, no puns) from the fertile (umm...) minds of the fanatical cult that kept www.angryflower.com alive for centuries. Who would have thought that an under-appreciated 21st-century web-comic could have such long-reaching influence?
