SPOTTED: NASTURTIUM FLOWER

I was leaving to take the puppy on a walk today, and while we were walking past the garden, I caught a glimpse of this little orange bud, and had a minor freak out.  IT WAS A NASTURTIUM FLOWER!!

So exciting!  I have been harvesting lettuce, and know these flowers will be excellent additions to my garden salads!  Has anyone ever done anything with the nasturtium stems and leaves?  I heard they are good to saute? Is that true??

I also spotted this lovely black krim flower yesterday:

And on top of all of that, I harvested some tiny green onions on Sunday:

They tasted delicious in my fried rice.
