Lance Hill, who posts below, says the type of chayote we are saying to get will not work in the US. Keep reading if you want to grow them, this turns out to be a more complex question than we all expected.

The imported "Chayote", which are sold at stores and mercados, are primarily grown in Costa Rica at nearly 5,000 feet. I envy your climate with 2300 feet altitude and only 60 inches of rainfall, but to grow at a few feet above sea level and with nearly 100 inches of rainfall annually, it takes specialization. In Australia, the Philippines, and other areas, Chayote is virtually an invasive species. This is covered in the free grower's guides at www.mirliton.org.
