This is a newly developed selection bred from the ground up for florists and gardeners who want reliable double flowers without the guesswork. The fragrance is a signature trait of stock, and the deep rose color carries that classic charm into modern growing. Compact growth keeps plants tidy in the garden or in a vase, while the cool-season preference means you can grow it in spring and fall when many other flowers struggle with heat stress. At just 4 inches of spacing, you can tuck quite a few stems into a small bed.
Stox Deep Rose Stock excels as a fragrant cut flower, bringing both visual depth and scent into floral arrangements and bouquets. The deep rose color pairs beautifully in mixed arrangements, and the fragrance is a distinctive feature that sets stock apart from many modern cut flowers. Florists value stock for its longevity in the vase and the generous number of blooms produced from a single stem.

Sow seeds ¼ inch deep into 128-cell plug flats 5-6 weeks before you plan to transplant seedlings into the garden or protected growing structure. Maintain soil temperature at 65-75°F for reliable germination. This timing allows seedlings to develop strong root systems before being set out.
Transplant seedlings into the garden after danger of frost has passed. Space plants 4 inches apart in full sun with well-draining soil at pH 6.5-7.5. Do not pinch the plants; stock flowers best when allowed to grow naturally without cutting the main stem.
Direct seed can be sown outdoors after danger of frost. Sow seeds ¼ inch deep directly where you want them to grow, then thin seedlings to 4 inches apart once they develop their first true leaves.
Cut stems for flowers when the lowest flowers on the spike have opened, typically around 90-105 days from sowing. Harvest in the morning or evening when stems are fully hydrated. Cut stems at a sharp angle just above a leaf node to encourage the plant to produce additional flowering shoots. Harvested stems can be stored at 36-41°F (2-5°C) to extend vase life.
Do not pinch or prune Stox Deep Rose Stock plants. The compact growth habit combined with the modern breeding for reliable double-flowering means the plant will develop its best form naturally without intervention.

It carries forward the legacy of Matthiola incana, which has been cultivated for centuries, while applying modern breeding techniques to improve consistency and reduce the frustration of plants reverting to single flowers.”
