Red Jewel F1 is very adaptable with a good holding ability. The head shape can be classified as semi-round to round and the internal quality is excellent with very dense layering. Red Jewel is very similar to Red Rookie and these varieties complement each other very well. The outer frame and head have a very dark red/purple colour. The internal colour is purple with white stems. At the seedling stage this variety is very vigorous, resulting in a good, strong plant for transplant. Uniformity is also very good in the field.
