Two Nations, One Seed

According to my map in Churning Mists, there are only two nodes for this quest. They very rarely spawn HQ emerald beans or any emerald beans at all. I saw a Youtube video showing multiple nodes spawning. I have abandoned this quest and reapplied still nothing. What am I doing wrong?

Emerald Beans are hidden items, which means they appear at random on the nodes they are capable of apearing on. They can appear on any of the 6 the Magma Beet nodes, so just keep looking.
