Notes: Indeterminate variety created by J and L Gardens and released in 2012. Plants grow to six feet tall, and tomatoes are deep purple on top and yellow on the bottom. I have seen this one also labeled as "Purple Yellow Light Bulb" which is the wrong name. This variety should not be confused with older sibling Bosque Blue, which is a similar but different variety (from the same tomato breeder). I have not been able to track down details on exact tomato size or if it needs to be caged/staked.
