Buy Gypsophila elegans 'Covent Garden' from Sarah Raven: Gypsophila elegans 'Covent Garden' is a simple, single gypsophila which could not be more different to the twee, top-heavy double form. This makes a wonderful filler flower in the garden and vase.
How about a meadow of cosmos? I have found that cosmos are a cool weather flower. While they grow profusely during a hot and humid Texas summer, they don't start blooming until the Fall when cooler weather arrives.
