Which flower did you choose to paint? Why? Is it native, an import, a new arrival, or endangered?
Is there cultural context? The Victorian Brits encoded messages into flowers; some of those meanings are still current. (Give a friend a red rose, another friend a potted daisy. Do they react differently?) A red poppy is a symbol of one thing, specifically because of culture. Chrysanthemums mean different things in America and Japan.
And if the artist writes a statement: "This is just a painting of a pretty flower." that too is a political statement.
Please display your definition of "political" which makes sense in all our usual contexts but also makes at least some art unable to be viewed as political.
If I draw a painting of a pretty flower, that does not challenge you. It's just nice to look at.
