Introduction: The plant decorations are considered as the most obvious designs that are used elaborately in different works of art. They are also used frequently in architectural decoration, particularly the ones made of stucco. The way these plant ornaments are composed characterizes the period in which they were created though many of these compositions have been repeated frequently over centuries. The goal of this research is to study the typology and classify the significant plant compositions in the stucco decorations from the Islamic period to the fourteenth century. In order to achieve this goal, the following questions should be answered:
- What are the most popular plant compositions in the stucco decorations from the Islamic period to the fourteenth century?
- Which compositions can be considered as the significant features of plant ornaments in a certain period?
Conclusion: The data was collected based upon written sources and field research (photography, linear print of the images) and analyzed through comparative-historical method. The results of this study suggest that the compositions existing in the samples can be classified into 9 groups some of which have been repeated in all historical periods, like the two and three-arabesque compositions in the margins and delicate joint/ stems with snail-shaped arches. But some of these compositions, including multi-layered plant compositions, delicate plant stems in the backgrounds, snail-shaped arches, etc., were evolved in some centuries, i.e. 13th and 14th centuries, or used more frequently.
