Lots of herb flowers in the garden now. The mints seem to be the most popular with the bees.
The fennel plants are full of flowers. Leaves (and flowers, too) have a licorace flavor, but it's the seeds that pack the big taste. If you buy fennel seeds in the store, you'll get the brown dried ones, but the less mature green ones are better tasting. If you want seeds for making more fennel plants though, you'll need to let them get to the brown dry stage.
Another herb with tasty seeds is cilantro. Fennel and cilantro are in the same plant family, Apiaceae, which has several other members with flavorful seeds: celery, dill, caraway, anise and cumin. The pretty little white flowers of cilantro are edible and have a sweet and very mild cilantro taste. The seeds of the cilantro plant, by the way, are given their own name (coriander).
