Oxypetalum solanoides (Pink Tweedia) [10 Seeds]

$4.50

Germination Information: Surface-sow (or just barely cover) the seeds indoors under lights in warm conditions in early to mid spring. Sprouting times can vary widely: usually anywhere from around 2 weeks to 3 months. Soaking the seeds in water overnight before sowing, and using a heat mat to keep the growing medium toasty warm, can help to encourage quicker, more complete germination. One time I grew pink tweedia from seeds, I started them on a moist paper towel at 70°F on May 12, and the seeds sprouted by May 20. Another time, I sowed in a pot under indoor plant lights on March 10, and germination started on March 18. 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 a little smaller and 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.

Pink tweedia is 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. I overwinter my potted clumps in my unheated, mostly dark basement and barely water them; the leaves drop and the remaining stems look rough. In late spring, I cut them back to about 6 inches and then set them out after the last frost date and begin watering again. They re-sprout quickly and produce an abundance of bloom in early to midsummer.

Collected in September and October 2023. At least 10 seeds. Shipping to US addresses only.
