Hi guys, I planted this flower a few years back from a cutting from somewhere. I fell in love with its bright purple color. I put it in a glass of water first just to preserve it for a few days, but then I saw some roots coming out so I decided to plant it outside. It grew nice and had lots of flowers, but when it became bushy and leaves started drying out I decided to pull it out. After a few weeks I saw some new plants growing from where I pulled out that plant, I let it grow and discovered it is the same flowering plant. Then it grew more flowers but this time with lots of other colors. It is so amazing, now I have pink, light purple, white, and yellow and it just started with that one colored flower I cut off. Can anyone identify it for me please.
