Flowers have a hard time keeping secrets.
Flowers are obvious, streaming scent molecules smelled by bees while blazing away in glorious Technicolor. Flowers are touchable. Any botanist, bird, bat, bee, child, gardener, ant, hummingbird or horticulturalist can and will inspect, ingest, pick, probe, or stomp them. Even genetically modify them. We think we know a flower when we see one.
