Although you might need to do a bit of a Google Image search for pictures of poppies in order to get the whole thing into your head visually, this poem doesn't really do anything too crazy in terms of sheer comprehensibility. The images jump around a little – Whoa, bees! Whoa, opium! Whoa, skirts! – but they're all pretty clear, and they all build up to give us a surprisingly coherent picture of a pretty crazy flower.
