Make room for flowering stock in your early spring garden. This bloomer is frost-tolerant and releases a spicy clove scent. Clip spent flower stalks to encourage more to form. In warm regions, stock flowers all winter. In cold-weather zones, look for plants in early spring. Plant as soon as you see them for sale. Landscape use: Plant where you can savor the fragrance. Use in mass plantings in beds near paths and entries or tuck into pots on porches.
