And takes about 80 days from transplant it turns dark blue on the top and the bottom is a bright red when fully ripe. Has a very robust tomato flavor the indigo series is very hard to find and can only be found when you buy tomato seeds online these are open pollinated and non gmo. The indigo blue and all the tomatoes from the indigo series comes from wild tomatoes not farmed to our farmers market friends you must have some of the indigo series. You will have tomatoes that hardly anyone has ever seen let alone seen at a store... This variety is indeterminate and in warmer areas will produce very heavily we get. Good results in zone 6.
