The Shasta Daisy has a nice ring to the name. According to Wikepedia it is a hybrid daisy derived from Chrysanthemum maximum and C. lacustre, having large white daisylike flower heads. As cut flowers, they last ten days in the vase.
More info: A hardy perennial, forming dense colonies once established. Native to Europe, it has naturalized throughout all regions of the United States. The white petalled flowers with golden yellow centers are borne individually on single erect stems. Compared to its cousin, the Ox-Eyed Daisy, Shasta Daisies generally grow 6 to 12 inches taller and have a larger flower head diameter. Prefers full sun to partial shade in fertile soil.
Leucanthemum is a wonderful choice to be grown as a specimen or en masse in the perennial border, in naturalistic landscapes, to attract butterflies, for garden bouquets, and even large containers. It can be one of the main stalwarts of the summer border. Plant with Perovskia atriplicifolia (Russian sage) for a long season of bloom. Place Scabiosa columbaria ‘Butterfly Blue’ (pincushion flower) in front and add Veronica ‘Royal Candles’ for a lovely combination of white, blue and blue-lavender. For extra zing, add Crocosmia ‘Lucifer’ a brilliant scarlet red, summer flowering bulb.
