Choy sum

Choy sum, often referred to as Chinese flowering cabbage, is a popular leafy vegetable in Chinese cuisine. It belongs to the Brassica genus, which is part of the mustard family. The name "choy sum" comes from Cantonese and means "heart of the vegetable."

This plant is easily recognizable by its yellow flowers and green leaves with serrated edges. It can grow up to 40 centimeters tall. Choy sum is an annual herbaceous plant but can occasionally take on a subshrub-like appearance. It thrives in soil with a pH level between 5.6 and 7.5.

One of the notable features of choy sum is its siliques, which are seed pods capable of holding between 4 and 46 small, round seeds. The plant typically begins to flower after developing 7 to 8 leaves and reaching approximately 20 centimeters in height.
