Quince

Introduction

Quince, a deciduous shrub belonging to the Rosaceae family, has been utilized for centuries in traditional medicine and culinary practices, exhibiting a rich history and diverse applications warranting comprehensive exploration and discussion.​

Botanical Overview

Quince (Cydonia oblonga) is a deciduous shrub or small tree native to Asia and parts of Europe, belonging to the Rosaceae family.​ It is characterized by its broad, ovate leaves and fragrant, golden-yellow flowers that bloom in late spring.​ The quince fruit, a pome with a fuzzy, yellow skin, is typically harvested in autumn and used in various culinary and medicinal applications.​

The quince plant can grow up to 5 meters in height and has a broad, spreading habit.​ Its bark is smooth and gray, while its leaves are alternate, simple, and pubescent.​ The plant’s growth habits and morphological characteristics make it a valuable species for horticultural and botanical studies.​ Quince is also used as a rootstock for grafting other Rosaceae species, such as pears and apples.​ Its adaptability to different environmental conditions and its low maintenance requirements make it a popular choice for gardeners and horticulturists.​
