  • Posted by Catmint20906 (PNW WA half hour south of Olympia - Zone 8a) on Aug 27, 2014 6:59 PM concerning plant:
    Rudbeckia (Rudbeckia hirta) 'Denver Daisy' is an extremely attractive Rudbeckia cultivar with a generous mahogany brown center and bright yellow rays. I learned a valuable lesson this season in what is meant by a 'self-seeding short-lived perennial or biennial' when what appeared to be my 'Denver Daisy' cultivar reseeded instead as 'Prairie Sun'! It turns out that 'Prairie Sun' is one of 'Denver Daisy's' parents. If it had reseeded as 'Denver Daisy,' I might never have known that it wasn't the exact same plant re-emerging.

    Rudbeckia hirta is a larval host plant for the Silvery Checkerspot and Gorgone Checkerspot Butterflies. It is a very good source of nectar for butterflies and is a Monarch Way Station plant. Rudbeckia hirta attracts a variety of native bees, including longhorned, leafcutter, cuckoo, bumble, sweat, green sweat, and small carpenter species. It also attracts a variety of beneficial insects to the garden, including bee wolves, soldier beetles, bee flies, and syrphid flies.
