Germination Information: Start the seeds indoors, just covered with growing medium, under lights in warm conditions in early to mid-spring. Soaking the seeds in water overnight before sowing, and using a heat mat to keep the growing medium toasty warm, can help to encourage good germination.

Description

When it comes to blue flowers, blue tweedia (Oxypetalum caeruleum or Tweedia caerulea) is in a class by itself. Grown an annual, it generally reaches about 2 feet tall, with somewhat sprawling stems that carry fuzzy, slender leaves and sprays of five-petaled, summer blooms in an amazing shade of sky blue. The flowers of this milkweed relative are followed by slender pods that split to release silky-tufted seeds. (If you don’t intend to collect seeds, I suggest removing the developing seedpods to encourage rebloom.) Best in full sun. Perennial in Zones 8 to 10 (where it can scramble up several feet higher with support), but you can grow it as an annual anywhere. Or, treat it like a tender perennial and bring the plant indoors for the winter to get many more flowers and earlier bloom the following year.

2020 supply sold out. Fresh seed should be available by September 2021. At least 12 seeds.

    Great germination rate with these under lights and on a heat mat sown in late Spring — they are a bit slower to emerge but seedlings came up about two weeks after sowing. A neat plant! The leaves are quite charming.
