I think they have to be a certain age before. I just notice mine had a red leaf this year. It caught me off guard. These red leaves are really nice looking on the plant once they start growing them.

According to nurserymen who grow large numbers of them from seed, they exhibit the color from a very early age, as seedlings. There is always a range of color from soft orange tones to rust, to vivid red and dark burgundy, and each plant will maintain that color. It's unusual to get a green one, but it happens. The bad news is if it is green, it will stay green.

But...if the leaf was opened a day or two before you noticed, it may have turned green in that time. They open with color, but every leaf turns green once open, over a couple of days to a couple of weeks. So carefully observe the next spear as it opens, that will tell you the true color. And yes, it may intensify as the plant matures. But if it's green, it will stay green.
