Very impressive! And they look prettier than what I saw at the nursery today. Do you mind sharing what company you bought the seeds from?

Katob, it's been more decades than I care to remember since I last grew vinca! Back then, they were piddly slow to establish and a real mess of leaf spot and stem rot disease, forget it, never had grown them again! But, breeders are claiming do have gotten the upper hand with all that and have produced these magnificent large and lasting showy flowers. Most of these I'll put in hanging baskets, but a few in the ground to see how they perform in my sometimes less than warm summers.

Aloha, I purchased the seed from Stokes Seeds Canada, they also have a US branch, Harris Seeds offers them as well.

I'll post again when I've got big overflowing baskets of color! :)

I’ve managed to kill them years ago. And so am not wanting to try them again without more confidence. I’m in north Texas; I believe you and I have different climates. We will have constant sun & heat soon. No cooling off at night. 🌞🌞🌞 😊 Look forward you seeing your baskets of flowers!

This is my first year with the "Cascade" series - I ordered the violet. I grow vinca from seed every year and it's pretty easy but man the stems rot easily, I have to be super-careful about not over-watering. Interestingly, the "Cascade" are rather puny next to the regular Cora series I've got going under the lights - no clue why. Yours look great, though.

Mxk3, my plants have developed at a good rate and now beginning to branch and trail. They really seem to appreciate warmer temperatures and had slowed right down when I had lowered the night temps. Sclerotinia was the stem rot issue that plagued them when I had grown vinca years ago, supposedly 'Cora' series are now immune to such, will be interesting to see how they have managed when all is said and done.

Aloha, yes, our growing seasons are much different when it comes to the HEAT factor, here rarely is a summer's day tooo hot or humid to prevent one from spending the entire day out under the sun.

A buddy in California was telling me of these vinca thrive in his oven baked garden.

As your name implies, maybe, possibly, 😃 are you in zones 3/4? About where are you located, FrozeBudd_z3/4?

I find Catharanthus very easy to grow from seed. It's a must have in my sunny locations where it thrives in the long hot summers. When I lived in coastal SC, Catharanthus was a successful parking lot choice, typically the most hostile of all growing conditions.

Aloha, yes indeed I'm zone 3 / 4 central Alberta, a rather very extreme climate, as most of Canada is for that fact, lol.
