I’ve been growing One Kilo Slow Bolt for several years.
Features:
1) The heads can grow up to11 inches tall and 20 inches wide which includes the lateral leaves.
2) One Kilo has crunchy stems.
3) If you decide to harvest the outside leaves, this plant will keep giving just like Little Jade.
4) One Kilo grows in an oblong shaped head.
5) It has a mild and sweet flavor.
6) The leaves are green with white stems and veins. The interior leaves are green and yellow.
7) One Kilo heads can be up to 2 1/2 pounds.
