Dense columns of snow-white double flowers with a genuine clove-like scent set this variety apart immediately. The blooms aren't merely decorative; they're edible, adding a sweet, nutty complexity to salads and other dishes when used as garnish. Japanese in origin, White Surf Stock germinates quickly in 7 to 14 days and blooms early in the season, rewarding impatient gardeners with flowers when many other plantings are still establishing. Its frost tolerance and preference for cool growing temperatures (60 to 75 degrees Fahrenheit) make it especially valuable in spring and fall gardens where other tender annuals struggle.
White Surf Stock shines as a fresh-cut flower, with tall stalks of densely packed blooms commanding attention in arrangements or as striking focal points in a vase. Beyond the vase, the edible flowers provide a sophisticated garnish for salads and other dishes, their sweet and nutty flavor and elegant appearance elevating simple plates into something more refined. The strongly fragrant blooms also make this variety attractive for fragrant garden borders where their clove-like scent can be fully appreciated during cool morning and evening hours.

Start seeds indoors 6 to 8 weeks before your last spring frost at temperatures between 65 and 75 degrees Fahrenheit. Seeds will sprout in 7 to 14 days. Keep soil consistently moist but not waterlogged during germination. Transplant seedlings into individual containers once they develop true leaves, maintaining the same temperature range until ready to move outdoors.
Harden off seedlings by gradually introducing them to outdoor conditions over 7 to 10 days. Transplant outdoors after the last frost date, spacing plants 12 inches apart. White Surf Stock can also be transplanted earlier than frost-tender annuals due to its frost hardiness; in cool climates, you can transplant as soon as soil is workable in spring.
Direct sow seeds outdoors after the last spring frost, pressing them lightly into soil at a depth of 1/4 inch. Space seeds about 12 inches apart. In mild climates, fall direct sowing 8 to 10 weeks before the first frost will extend the blooming season and produce stronger plants.
Harvest flower stalks for arrangements when the lower flowers on the stalk are just opening; they'll continue to open as the arrangement sits in water, extending vase life. Cut stalks in the early morning or late evening when stems are most turgid. For culinary use, pick individual florets as needed; they're ready when fully open and at their most aromatic. Removing spent flower stalks encourages continued blooming throughout the season.
