A master gardener has written a guide to growing the vinca flower from seeds. This flower, known as the rose or Madagascar periwinkle, has small blooms in white, rose, red, or purple. It is not resistant to frost, but can be grown as a perennial. The guide describes how to gather and store the seeds. Then it tells when to plant the seeds – three to four months before the expected last frost. The article has a photo of the vinca.
- Plant vinca seeds indoors three to four months before the last frost of the season.
- Collecting vinca seeds from mature plants isn’t difficult, but growing annual vinca from seed is a little trickier.
- Cover the seeds lightly with soil and lay a damp newspaper over the tray because germinating seeds of vinca require darkness.
“When collecting vinca seeds, look for long, narrow, green seedpods hidden on the stems beneath blooming flowers.”
