Planted vinca the year before last but not this year ! The area this year has volunteer vinca that is coming up ! Last year I saw no seed pods or any seeds on the plants so how the new vinca is coming up I don't know! Last fall I pulled the old vinca up so I am baffled as to the new crop of flowers if no seeds! Do the vinca have roots that not all come out of the ground ? No other vinca in any area near my flower garden ! Please someone have an idea? Cold winters here in Missouri so whatever is in the ground still came up in June!

Sneaky little VIncas!

Hi Vinca! It would have been vinca seeds that fell last year. A vinca seed is like poppy seeds or pepper flakes, hardly noticeable. This year after they have flowering and some of the blooms have faded. You can look and collect seeds. Take white paper and gently shake the vinca. Seeds should fall into the paper. Keep repeating the process every two weeks or so. At the end of the season shake the plants out on the ground. Vinca from seed takes a little longer to grow because vinca likes soil temps in the 70s. May you be blessed with a safe and wonderful weekend!

Hi & welcome! Are you asking about one of the creeping vines (Vinca minor or major,) or the upright plant sold as annual where not hardy, Catharanthus roseus?
