I learn something new everyday!* I didn't know there was one named 'Mystery'.* I'm sorry I didn't understand what you were saying.* :shock:* I will say that most growers will give the size after 10 years of growth.* I have some very slow growing camellias that were 4' tall after 10 years.* Now after 28 years they're about 8' tall and have been pruned back for the last couple of years.* If you find a site that says a plant will get taller then the other sites you found, go with the tallest one and still give it a bit more space.

When weeding, the best way to make sure you are removing a weed and not a valuable plant is to pull on it. If it comes out of the ground easily, it is a valuable plant.
