I never had a Ti plant live long enough to grow let alone grow,trunk a bit, and now flower. You know in Hayward,we have good weather,great water quality..and after that I close my mouth. But,back to plants. I've seen this called "Red Sister"..but I also have seen that neon pink and red Ti (that I also have) called R.S. I would say this particular plant has really been vigorous for me. Never protected..but now that I know how special it is- for here- I might do extra next winter IF needed.
