About This Resource

December is an ideal time to start various flower seeds, particularly for those that require a cold period for germination. Gardening expert Sarah Jay highlights nine flower seeds suitable for sowing this month, including Oopsy Daisy Calendula, Mammoth Blend Sweet Pea, and Colorado Blend Yarrow. These seeds can be sown directly outdoors or started indoors to give them a head start. The article emphasizes the importance of cold stratification for certain seeds, such as columbine and lupine, which thrive in cooler conditions. Additionally, flowers like purple coneflower and milkweed are noted for their benefits to pollinators, making them excellent choices for any garden. By starting these seeds in December, gardeners can look forward to a vibrant spring bloom.

Key takeaways

What to know before you act on this, from the SteadScape editors.

  • Sow Oopsy Daisy Calendula seeds outdoors in December for a vibrant spring bloom; ensure soil is well-draining and moist.
  • Start Mammoth Blend Sweet Pea seeds indoors by mid-December to transplant outdoors after the last frost in your area.
  • For Lupine, scarify seeds with sandpaper before sowing directly in December; avoid planting invasive species outside their native range.
  • Plant Purple Coneflower seeds directly in December; they thrive in hardiness zones 3-8 and are drought-tolerant once established.
