Wild strawberries grow on every continent except Africa and Australia/New Zealand. Wild berries are often small and tasteless and may be other colors than red.
Today's strawberries are the result of a cross made in France 250 years ago between fruits from North and South America. Early European explorers of the 1500s, took samples from the Virginia area back to Europe where they attracted a lot of attention because they produced larger fruit, were more productive and had brighter red coloring than those common to Europe at the time.
In the early 1700s, a French spy mapping Spanish forts in Chile, found another genotype which produced very large berries and took them back to France. The plant was entirely female and would not produce until it was placed next to the North American variety which produced pollen to fertilize it. The new variety was named Fragaria x Ananassa. Most of the stawberries grown today come from this cross.
About 2/3 of the strawberries grown in the United States are produced in California.
Strawberries can be grown in nearly any part of the West. The two types are ever bearing and spring bearing, or June bearing varieties. Spring bearing types depend on long nights to trigger blossoming. As the summer days lengthen, the plants quit producing berries.
Everbearing strawberries do not depend on long nights and are referred to as day neutral. More plants are needed to produce adequate crops.
