OutsideprideBurgundy Periwinkle Seeds for Planting – 50 Pcs Annual, Fast-Blooming, Heat & Drought Tolerant Vinca Flower Seeds with Vibrant Colors Ideal for Gardens, Beds, Borders & Containers

I planted the same day as a more inexpensive vinca seed pack found here on amazon (bumped up to the healthy packs in picture) that didn't even try, these ones definitely grew. Seedlings get morning sun in Phoenix az, I did put some in a couple crowded pots in full all day sun that are also doing good. Will be buying more. This is about 4-5 weeks out. Slow growing but could be me, and worth it these last forever and never stop blooming.

Planted 96 of these indoors next to 2 trays of other vinca colors from the same seller. Same soil-- same heat-- same conditions. Only 6 out of 96 came up. I suspect OLD seeds, since the other vinca seeds fared much better-- almost all of those 192 plants came up. I'm very disappointed.

My seeds germinated quickly, though it took several months for the plants to mature. Worth the wait!

Not a perennial plant, very few developed. Best to get plants/seeds local

I planted 27 of the 50 seeds randomly doing 2 or 3 per peat pellet. Following the instructions and then kept them in the dark for 5 days. When I peeked in on them on the 5th day, they were already sprouting. I kept them in the dark until day 7 and then introduced them to light.Every seed germinated and sprouted. I look forward to adding them to my flowerbeds in a couple more weeks when they are a little more hardy.

Every single seed germinated.

Grew these from seed, months later find I have a ton of American Knotweed. Bought several varieties and they are all garbage. Past the return window...Amazon, are you listening?

Started Vinca seeds from 3 seed companies using same method for all three (moisture, no light, warmth, seed starter soil). Outsidepride seeds BY FAR exceeded the germination rate and speed of the other two, germinated in 4 to 5 days. Will buy from them again.
