Zeedman, you're so right about the number of wasps, bees and flying things attracted to these nectaries. The field pea patch gets covered with them. Happy pollinators!
And they are docile. When I pick peas and there's a wasp on a pea I want, I just gently tap the stem the pea is on and the wasp lazily moves somewhere else.
Just picked my first yardlongs yesterday, 'Red Noodle'.
