I have had many of differnt colors. Last year I had the hybrid kind that had every color of the rainbow in one plant. It was beautiful!!! I decided to take cutting off them and grow them. When they came up, every last cutting bloomed purple. I also had some red and pink ones. I took cutting from it and planted them in my moms yard. Every last one of those came back purple! Now why do the different color cuttings always come back purple when the flower color you cut is a entirely different one??
Previously I had heard of portulacca reseeding and growing a second year in a row. However I had not heard of cuttings blooming purple.
TY for the link to the article. I was asking if you had pics of your plants because I thought you wanted to discuss the specific plants you have. I'm a huge fan of the Portulaca genus and hope to eventually have met all of its' members. The article calls purslane (Portulaca oleracea) an annual, which it is not. Portulaca is a genus containing various species but that is not clear when reading the article, and definitely muddled when one gets to the list of cultivars, many of which are cultivars of P. umbraticola (often called ornamental purslane,) not P. grandiflora (moss roses.) Not that I object to the mixing of common names, which are just nicknames, but the author speaks about both as if they are the same species. P. umbraticola: https://www.gardenstew.com/plantstew/20429 P. grandiflora https://www.gardenstew.com/plantstew/20419 More information about why so many P. umbraticola plants are lumped-in with P. grandiflora, and often still called hybrids or cultivars of that.) http://australianportulaca.blogspot.com/2013/08/the-history-of-portulaca-umbraticola-in.html
I have a pot that has portulaca come back yearly for 7-8 years. White and pink blossoms are beautiful, so much so my cats napped amongst them.
