How would you plant flowers, shrubs and trees on a ziggurat? Remember, ziggurats had different shapes, heights, levels, slopes, stairs, etc.
How would you water your garden? OK, you could have lots and lots of slaves going up and down the steps... but what mechanical method can you invent? Remember — this was long before steam, gas, oil and electricity were used for power!
Early humans discovered that they could grow certain crops to use as food. Agricultural communities developed near the Mediterranean Sea about 10,000 years ago. At various stages in history, people cultivated wild plants and developed the idea of having flowers for pleasure.
Some modern humans regard flower gardens as an unnecessary luxury. What do you think? Should gardens be for growing food or flowers or both? How should be use our gardens? Should we have gardens at all? Many people throughout the world don't have such a luxury.
Gardens sometimes have statues on display. In ancient times, they might have been statues of gods. Later, they could have been emperors. Some were mainly of beautiful people. A park in Ballarat (near Melbourne, Australia) has an avenue of busts — statues of head and shoulders only — of all the Australian prime ministers.
If you could choose 10 people whose statues should be in a garden or park, who would you choose and why?
You are the chief horticulturalist in the first intergalactic mission to an inhabitable planet. You have to create the first garden. What will be in it, and why? Assume that the climate and atmosphere are the same as on Earth, but remember that Earth also has a variety of climates... and... people from different countries eat different kinds of food, too.
