When to Grow

Sow Silvery Rose indoors 4-6 weeks ahead of your last frost date and move the transplants out after the last frost, or direct seed once frost has passed. Press the seed onto the soil surface instead of covering it, since light is required for germination, and hold a germination temperature of 70-75°F through the 10-20 days it takes to sprout. The ivory-and-blush blooms arrive about 75-80 days from sowing. The plants are not frost hardy.

How to Sow and Plant

  • Seeds germinate in 7-14 days.
  • Sow seeds indoors 4-6 weeks before last frost and transplant outdoors after last frost, or direct seed after last frost has passed.
  • Surface sow seeds and gently press into soil, as seeds require light for germination.
  • Ideal germination temperature 70-75 F.

PESTS/SPECIAL CONSIDERATIONS

How to Save Seeds

  • To save seeds, allow the flowerhead containing the seeds to completely mature and dry on the plant, then clip it off and place in a container.
  • Working over the top of another clean, opened container, rub the flowerheads to separate the seeds.
  • Store over winter in a cool, dark, dry place.
