The Geraniaceae family, also known as the Geranium Family, belongs to the order Geraniales. It encompasses several genera, including the well-known genus Geranium, as well as Pelargoniums, which are commonly referred to as “geraniums” in horticulture. The Geraniaceae family primarily comprises herbaceous plants or subshrubs.
Within the Geraniaceae family, there are a total of seven recognized plant genera, encompassing approximately 841 species. The genus Geranium is the largest within the family and is known for its diverse range of species. Pelargoniums, on the other hand, are popular garden plants widely cultivated for their attractive flowers and aromatic leaves.
Members of the Geraniaceae family exhibit a variety of growth habits, but they are predominantly herbaceous, meaning they have non-woody stems. Some species may develop a woody base or become subshrubs. The plants in this family are known for their often palmately lobed or divided leaves, and the flowers typically have five petals and a distinctive arrangement of stamens and pistils.
The Geraniaceae family has both ornamental and medicinal plants, and its members are widely distributed across different regions of the world. They are valued for their aesthetic appeal, as well as for their fragrance and potential therapeutic properties. The popularity and diversity of Geraniaceae plants have made them a significant group within the realm of horticulture and gardening.
Geraniaceae family members have lobed or divided leaves. They are sometimes opposite or alternate and have stipules. The flowers are symmetrical. They are hermaphroditic or sometimes zygomorphic. They have free petals and sepals are connate. The stigmas are also free. They are usually pollinated by insects. The fruits are usually schizocarp consisting of three or five achenes.
