Most Cherries require another Cherry variety for pollination.  Some varieties are entirely self-fertile.  To use the Pollination Chart: 

1. Select the desired variety to be pollinated from the top of the chart 

2. Potential pollinizers are listed in the column beneath the desired variety 

3.  If the intersecting square is white the variety will be pollenized. 

4.  If the intersecting square is black the variety will not be pollenized.
