Hello Andrea67, thanks for starting this Thread. If you've saved some seed, you can try for next year, and you might get lucky. I was surprised to find some Portulaca growing this year that came from plants I had purchased 4 years ago. In 2017, I bought a pack of Portulaca Happy Hour.
I planted them beside my Daylily Swirling Water, but felt they were in too much shade.
In 2018, a seedling was found, but got transplanted to the Iris slope for better sunshine.
This year 2021, three years later, Portulaca seedlings popped up behind the Irises and surprised me.
And the pink Portulaca seedling looks like the Happy Hour Portulaca from 4 years ago!
- Have fun with your Portulacas!
