Please take a look at the map of the area. General botanical description and a photo can be viewed below:
La Retuerta is situated in the central part of the Ebro valley, east of Zaragoza, in northeastern Spain. The extreme climatic conditions of the area have produced a vegetation similar to that of the North-African steppes. This climate can be summarized as follows: large annual range of minimum and maximum temperatures, oscillating from -10 oC to more than +40 oC; frequent frost in spring; prevailing winds from the NW and the SE (cold and warm, respectively), both with great desiccating power; low annual rainfall (200-400 mm); water deficit over 300 mm.
