    Strawflowers (Xerochrysum bracteatum).

    The Australian beekeepers know about these flowers, native to Australia. Supposed to be good sources of nectar, there is a honey bee in the picture, one of several this morning. She rudely turned her posterior to the camera so I didn't zoom in on her :\.

    DW likes to have a few strawflowers in the each year so that she can have them for dry arrangements. They have just started to bloom and will be blooming until frost.

    The honeybees are not so much the beneficial insects I'm thinking about for my annual vegetable garden. They have lots of acres of alfalfa nearby, as well as vetch and the knapweed has just begun to bloom. No, the yellowjackets and ladybugs will soon be covering these plants. I'm not sure what they are up to but the entomologists tell us that all 3 of these insects drink nectar.

    The wasps are a threat to the honeybees so those will move on. Meanwhile, Steve will have to move very slowly and carefully around these plants. The yellowjackets often ride along as I carry strawflowers out of the garden. Of course, the ladybugs do too :).

    I don't find aphids on the broccoli and cabbage growing beside these plants. This has been the situation for the last few years. Cabbage can be turned into rotten garbage by infestations of aphids. Having strawflowers beside the cabbage seems to eliminate the aphids!

    Not surprisingly, I don't have to spray the strawflowers for pests although they suffer a little insect damage during the weeks before they begin to bloom. Beneficial insect magnets :D!

    any red or yellow perennials tend to get our interest. not sure how they would fare in our heavy clay soils, but perhaps could find a space for them someplace else. thanks for bringing it up. :)
