What themes can be used for plant specimens?

Let me talk about my thoughts below:

1 Theory of Evolution. Display plant specimens from low to high, such as gymnosperms and angiosperms.

2 Geographical location: Display from the geographical landscape, such as tundra, grassland, coniferous forest, deciduous forest, and broad-leaved forest, which are representative.

3 Novelty: Display unique plants, such as plants with the largest flowers, smallest flowers, flowers that can eat insects, etc.

4 Plant Parts Show the functions and characteristics of flower stems, roots, leaves and other parts.

5 Special plants such as medicinal plants, edible plants, etc.

That’s all for now, I’m going to eat first.
