Yellow Stock's compact growth habit and consistently double flowers set it apart for gardeners seeking reliable fragrance and form without fussy selection. The breeding work behind this cultivar focused on making double blooms the rule rather than the exception, saving time spent roguing out inferior plants. Spring and fall plantings perform best, taking advantage of cool weather to produce blooms at their most fragrant and longest-lasting. At just 4 inches spacing, you can fill garden beds and vases with remarkable abundance.
Stox Yellow Stock exists primarily as an excellent fragrant cut flower. The double blooms and strong fragrance make it a natural choice for fresh arrangements, bouquets, and the kind of heirloom-feeling nosegays that have made stocks prized since Victorian times. Gardeners grow this variety specifically for cutting and bringing indoors, where the fragrance fills a room.

Sow seeds ¼ inch deep into 128-cell plug flats 5 to 6 weeks before your intended transplant date. Maintain germination temperatures between 65 and 75°F for reliable sprouting. This timing allows seedlings to develop sturdy growth before being transplanted into the garden or protected structure.
Transplant hardened-off seedlings into the garden after the danger of frost has passed. Choose a location with full sun and well-draining soil adjusted to pH 6.5 to 7.5. Space plants 4 inches apart. Immediately upon transplanting, cover plants with row cover to protect them from flea beetle damage.
Direct seed after the danger of frost has passed, sowing seeds ¼ inch deep into prepared soil. For succession harvests and continuous bloom, make sowings every 2 weeks during spring and fall growing seasons.
Cut flower stems when blooms are fully open and show good color. Harvest in the early morning when stems are most turgid and will hold water longest in the vase. Cut stems at least 12 inches long, stripping lower foliage before placing in water. For maximum vase life, store cut flowers at 36 to 41°F after cutting.

“Stox Yellow Stock represents a deliberate breeding milestone: the development of a stock variety selected from the start for high-quality double flowers and commercial viability. Rather than relying on traditional stock-growing knowledge where only a percentage of plants produce fully double blooms, this cultivar was bred to eliminate that uncertainty. Johnny's Selected Seeds introduced this as a new variety, reflecting years of selection work to stabilize the double-flowering trait while maintaining the compact growth and fragrant character gardeners expect from stocks.”
