If XXI The World was represented by flowers...

[Libra8ca]

angel-pink rose (the old and original kind with an open flower and just 5 petals,)
bull-dark Cattleya orchid, maybe chokolate brown
lion-orange Day Lily
eagle-oh yes, the Columbine

Excellent suggestions.

For the eagle I would also suggest Edelweiss (the real thing), they grow high up in the mountains in remote areas (amazing if you ever get to see one as they are rare).
For angel /aquarius I could also image a waterlily.
