They are a visible symbol of an event. Flowers of some kind or other grow nearly everywhere in the world. I grow literally thousands of flowers every year. I can't even comprehend anyone NOT growing at least one flower at all times. My african violets bloom on the coldest of winter days, offering hope against the bleak backdrop of winter.
Flowers are the very antithesis of war and murder and other beastly acts of mankind.
Flowers are hypnotic. Which brings me to flower power. Flower power is more than a 1960's slogan. The truth of the symbolism of flower power went beyond the Establishment's collective consciousness. Dorman and Bushy went to his house late one night and Ingle played the song for them.
