The Manzanilla (Manzanilla, Crataegus guatemalensis), grows abundantly in the Volcan de Agua and the harvesting season start in october and goes through january. It is a small fruit resembling an apple hence the name manzanilla (find a pinture of the tree here). I blogged about it previously in the post Manzanilla en Dulce.
The Manzanilla is a sight, smell and taste of Christmas. During this time you can find them at almost any market sold in strings. I paid Q8.00 per string. They are commonly used to adorn the Nativity scene or the Christmas tree but I have also seen them hanging as with pine strings as decoration outside and inside the house.
