Well... Since we're on the topic of rape for some reason, if you're in the United States you can often find flowers without leaves. It's pretty much just a stem and a flower.
This flower plant is actually a parasitic plant. Their seeds will lie dormant in the ground for years until an unlucky tree grows its roots near the seeds. The seeds will then sprout and immediately leach nutrients from the tree. Who needs leaves if you can just steal your nutrients from others.
What is this plant called?
Drumroll please...
"Broomrape."
