Use this quick-growing flowering leafy green like broccoli. Harvest the purple stems, flower buds and leaves.
Choy sum translates to “heart of the vegetable”. Each plant produces 10-15 crunchy stems which have an excellent sweet and mild mustard taste (the flower buds are the spiciest part). Harvest all parts of the plant when the flower buds appear–in other words when it starts to bolt–including its purple/magenta stems, yellow flowers/buds and dark green leaves.
Use Purple Choy Sum as a cooked or fresh veggie. It is much easier and faster to grow than broccoli, it is ready 50-60 days after direct sowing. Cold hardy and disease resistant.
