Hybrid flowers are rare, but setting up flower beds to try to grow hybrid flowers isn't difficult. Just put two flowers of the same type close to each other, and you might wake up one morning to discover a hybrid flower, with a different color, near those two!
How to grow a hybrid
Take two roses, or two tulips, or two cosmos, or two pansies, and put them next to each other. They can be on the same line or diagonally touching. Then, if you have a color combination that produces hybrid flowers, you might find a hybrid flower growing near those two one day. Hybrid flowers are very rare, though, and you might not get one for a long time.
About 3 to 5 new flowers will appear in your town every day. New flowers appear at 6AM.
Diagonal planting creates more spots for a hybrid flower to appear
Take a look at the illustration below. The Os represent two flowers of the same type. The Xs represent places where a hybrid flower might appear. You can see that there are 10 squares around the two flowers. These ten squares are where a hybrid flower could appear.

Now take a look at the below illustration. You can see that if you put the flowers next to each other diagonally, there are 12 squares where a hybrid flower could appear. This means that diagonally planted flowers have a slightly greater chance of producing hybrid flowers than flowers planted in a straight line.
