(2) For those curious, I actually wanted to add an Egyptian themed garden, i.e. a desert garden expansion, featuring pillars etc. to the western part of the map. Alas, I was already hitting the editor's object count limit, before adding all the trees, so I had to give up on that Egyptian idea. This might have been for the better.

Build time: 3-4 days.

Tip: Should you like to try out the map, you can download it via the Hidden Through Time main menu:
-> online -> online maps -> click on "all" button
-> under Search map: enter " AEons Botanic Garden "
and then play it.

(1) Having "used up" the Egyptian and Japanese themes, and having recently completed Assassin's Creed Odyssey , using the Roman theme seemed promising. Looking at the viaduct objects, it soon became apparent that it can be turned into something resembling an aqueduct, placing it between the terraced mountains created an interesting backdrop. Experimenting with free-form water expanses at the foot of the aqueduct for the first time, led me to add those white pillar blocks to keep the water "contained". While thinking on what to do with all the rest of the map, I added regularly spaced bordered beds and to become the desert garden. At this point the theme of a Botanical Garden made more and more sense. So I added a Japanese garden, and several arboretums (from Roman and pre-historic times). I turned a "bath house" into a tropical house, and another building into a storage "shed" for the gardeners. All the while framing the gardens in Roman "architecture", well mostly columns.
