There are a number of them on our property. As we only bought it a year ago I don't know how old the trees are. But the largest one is around 7 or 8 feet tall. I examine that thing so closely every time we are there which is usually once a week. I didn't miss the camphor blooms & they are very, very tiny. If anyone saw me examining that toothache tree they would think I was nuts! I get so darn close looking for blooms.
