The tomatoes are beginning to fruit. They are companion-planted with borage, which the bees love.
Alongside the chard and Russian kale, mustard greens are allowed to finish their life-cycle. Their yellow blooms add beauty, are tasty in salads and appreciated by bees. They help repel harmful insects. In the rear you can see yarrow. Although it gradually spreads and needs to be managed, yarrow is an excellent companion plant, attracting many beneficial insects, including ladybirds (aka ladybugs) and beautiful dragonflies. It has a protective energy for the garden.
California poppies have been interplanted with the beets and turnips mainly for beauty but also to attract beneficial insects. The occasional sunflower, in a location where it won't shade things out, also attracts beneficial insects and birds to the bed.
