Ingenious plant breeding has produced this amazing red sui choi (napa cabbage). The leaves are red throughout, but never bitter in this upright fall harvest wonder. Sow Red Scarvita several times starting June 15 for harvests from September to November. The leaves look incredible in salads and they keep their colour when lightly cooked. Lightweight row cover is recommended, as this beauty gets sown at the peak of the small white butterfly (cabbage moth) population. A simple physical barrier will prevent insect damage.
