What is this leaf?

I have a planter box full of nasturtiums. I planted them last year and they self sow, so no need to replant. Hummingbirds love them. I haven’t eaten the leaves or flowers, just used them to decorate the plate. You can also make capers from the seeds.

So, what did you think?

I haven’t eaten them yet! I just saw that picture in my internet travels and was curious.

Ah, okay. Didn’t realize that.
