This is one I have been wanting to talk about for a while, from my observations, wasps and yellow jackets are particularly fond of alium flowers, because of its size they can access the nectar more easily. this is one video of a Eastern sand was in the garden.
Wanda Kaluza has allowed me to share her vid on this topic.
this one features pleurisy root or orange flower that attract predatoy wasp, pollinator, butterfly etc.
