This is a stock bred with the home gardener in mind, engineered to simplify the selection of double flowers without the guesswork that older varieties demand. The fragrance is substantial and genuine, not the faint whisper you sometimes get from modern ornamentals. Germinate it between 65 and 75 degrees Fahrenheit, give it moderate water and a neutral soil pH between 6.5 and 7.5, and you'll have armfuls of cut flowers within three months.
Stox Silver Stock is grown exclusively as a fragrant cut flower. The blooms are ideal for floral arrangements, where they bring both visual presence and authentic old-fashioned fragrance to bouquets and displays.

“Stox Silver Stock is a recent introduction from Johnny's Selected Seeds, part of a deliberate breeding effort to address a long-standing frustration with stock flowers. Traditional stocks have always required careful observation and hand-selection to identify which seedlings will produce the prized double blooms, while others remain single. This cultivar was developed to streamline that process, making it easier for both commercial growers and home gardeners to achieve the full, ruffled flowers that made stocks beloved Victorian favorites.”
