Q.Geiger Tree In Northern Climates?
My parents and two of my siblings are buried in a cemetery in Wisconsin. The soil is very sandy. I know that the tree is primarily a southern coastal tree. Has there been a species or a mutation that have been developed that can withstand the cold winter climate in the Midwest?

This tree thrives in tropical climates. Our experts say the white-flowered relative Cordia boisseri is more cold tolerant, but that doesn't mean it can survive a Wisconsin winter.
