Thanks @Gail-Steman it’s took a long time for it to flower like that. It generally flowers late in the season.
Geezzz....Kazza...that hibiscus is amazing. May I ask the name of it? Absolutely stunning!!! Gail-Steman...that picture was taken in 2012 from an area at my job that I converted into a awesome garden!!! On to the next....
I think it’s White Chiffon (Rose of Sharon) https://www.gardenia.net/plant/Hibiscus-syriacus-White-Chiffon-Rose-of-Sharon
