Days to Germination:7-14 days
Matthiola incana. Stock, an old-fashioned cottage flower, can be sown outdoors after the danger of frost has passed, yet it is best started indoors 6 to 8 weeks before transplanting out after all danger of frost has passed. Sow seeds on top of soil mix, leaving the seeds uncovered but pressed firmly onto the soil surface, as light aids germination. Provide even moisture, strong light and luke warm water. Prepare a garden bed in full to partial sunlight with rich, well-draining soil. Harden off the seedlings by gradually acclimating them outside over 1 to 2 weeks. Carefully transplant them 12" to 18" apart. Prized for their spicy clove scent, Stock has stalks studded with small, semi-double flowers ranging from white to pale pink to deep burgundy. It makes a great garden display or cut flower. Summer flowering. Height: 18".
