Borage, this is a really good bee attractor if you want to help the pollination in your garden, its a herb and the leaves are edible and taste like cucumber.

Columbine, this is a great Hummingbird plant and also attracts bees, easy to grow from seed but the seeds need to be stratified so place them in some damp sand in a baggy in the freezer for a few days then into the fridge for a month then your will get really good germination rates.
