Most of our hardwoods have sap from a honey yellow to a blood red depending on the species.
You can get big sap pockets in the timber makes it hard when trying to cut clean boards.
This is a pic of a big old River Red Gum.
They still log Forest Red Rum in AU it grows tall and straight compered to River Red Gum.

Here's a pic of a very sappy hardwood it's called Bloodwood you can see how it got it's name. I've still got a couple of nice slabs of Bloodwood I cut years ago its hard to get clean timber with no sap pockets out of it.
