Oxypetalum solanoides (Pink Tweedia) [10 Seeds]

$3.95

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 really help to encourage good germination.

The last time I sowed these seeds (2021), I started them on a moist paper towel at 70°F on May 12, and the seeds had sprouted by May 20. Your experience may vary.

Description

If you’re a fan of blue flowers, you may already be familiar with blue tweedia (Oxypetalum caeruleum or Tweedia caerulea). This species, known botanically as Oxypetalum solanoides or Tweedia solanoides, is similar in growth habit and flower form–sprays of five-petaled, summer blooms and fuzzy, slender leaves on upright to somewhat sprawling stems to about 2 feet tall–but in soft pink rather than sky blue. The flowers are followed by slender, milkweed-like 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. Hardy in Zones 8 to 10, 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 more flowers and earlier bloom the following year.

As a side note: In fall of 2019, I dug up my first-year clump of pink tweedia, brought the pot into my cool, mostly dark basement, overwintered it basically dormant, then put it back outside in late spring, protected from late frosts. The plant was thrilled to grow again and produced a terrific show in June–much better than in the first year–and set many seedpods. I was hoping for an abundant seed harvest, but as the first few pods split, I discovered that the seeds were dust and the pods contained some sort of larvae. Fortunately, a few pods were spared, but my seed supply is once again very limited for 2021.

Collected in August and September 2021. At least 10 seeds.
