  • Posted by Catmint20906 (PNW WA half hour south of Olympia - Zone 8a) on Aug 23, 2014 2:52 PM concerning plant:
    Cosmos (Cosmos sulphureus 'Bright Lights') is sun-loving and easy to grow from seed. It has been a pollinator magnet in my garden, attracting numerous butterflies and visited by many bee species, including green, metallic, sweat, and longhorned bees.

    Cosmos also reportedly attracts a variety of beneficial insects to the garden, including lacewings, hoverflies,
    mini-wasps, pirate, damsel, and big-eyed bugs. These beneficial insects feed on common garden pests.
