Here are some real baby Japanese maples that I have grown from seeds. Most are blood good seedlings. As Cheryl mentioned JMs are slow grower especially red color ones , there are a few green color leaf type that grow faster. I have one that is 2 years old and it is already 4 ft. Height. JMs that grown from seeds will never look exactly like parent, it may look similar but not exact. You can tell by leaf shapes and color if you look at the pictures below but it's hard tell how they will look until 3rd or 4th year. I have 100 plus seedlings and I will try to keep 10 and rest will be gone to someone else.By the way all JMs sold in stores are grafted.
