Yup, Frankies Red takes about the same amount of time to ripen as the Yellow Dragon. Frankies Red flowers earlier and thus ripens a little earlier but I still do also have two fruits left on Frankies Red. I'll cut one open tomorrow and report back with fruit quality this late into the season.
If you see the pictures on reply #5 of this thread:
http://tropicalfruitforum.com/index.php?topic=13533.0You can see that my fruit were already ripe in December 15 and if I remember correctly, some were actually ripe in November. I looked at my old picture from the December 15 post and compared them to my fruit today and it sure looks like some of the same ripe fruit from December are the same fruit I harvested today meaning that they held on the vine for about 3 months if not longer because they were actually ripe before I took the picture.
The Yellow Dragons I harvested today look pretty horrible with many small brown and reddish specks all over the fruit but the eating quality is still excellent. I remember that I was still harvesting some straggler Simons Purple, American Beauty and Halkeys Comet when the Frankies red were ripening so if I'm able to somehow stimulate these varieties SP, AB, HC to flower early, I can almost get year round harvest as long as my Yellow can continue to hold on the vine for another month or two.
I will try to leave one of my yellow fruit for as long as possible to see just how long they can hang without going bad. I think April and May will be the months that are most difficult to get ripe Dragon Fruit.
