But have you ever wondered what collard greens are related to? In this article, we will delve into the fascinating world of Brassicas, exploring the closest relatives of collard greens and the characteristics that bind them together.
Introduction to the Brassica Family
The Brassica family, also known as Cruciferae, is a large and diverse group of plants that includes over 300 species. These plants are commonly referred to as mustard plants or cabbage plants, due to the presence of four-petaled flowers that resemble a cross. The Brassica family is part of the larger order Brassicales, which also includes other plant families such as Cleomaceae and Limnanthaceae. The Brassicas are widely distributed across the globe, with many species being cultivated for their edible leaves, stems, roots, and seeds.
Characteristics of the Brassica Family
Brassica plants are known for their distinctive characteristics, which include:
- Four-petaled flowers: Brassica plants produce small, four-petaled flowers that are typically arranged in a raceme or corymb. These flowers are often white, yellow, or purple, and are a key identifying feature of the family.
- Pungent flavor and aroma: Many Brassica plants have a pungent, sulfur-like flavor and aroma, which is due to the presence of glucosinolates. These compounds are responsible for the characteristic taste and smell of Brassicas, and are also thought to have medicinal properties.
