The Aztecs may have been violent and downright bloodthirsty, but they adored flowers, almost to the point of worship. The flower markets you'll find around the city are direct descendants of the ones that existed more than 500 years ago. The most splendid of these modern markets is the Jamaica Flower Market in Colonia Jamaica (pronounced Hha-mai-ka). It smells like a dream and is an explosion of color. Explore this vast warehouse with vendors selling simple bunches of flowers, to ornate funerary displays. Most business is in wholesale. Around the Day of the Dead, this market receives truckloads of marigolds. Should you have some sort of tulip or geranium emergency, the market is open 24 hours, 365 days a year.
