I picked my first O-15 yesterday, slightly soft with some color break. This is the first crop on a small tree. I am not sure what the "regular" season is but the other fruit on the tree look like they will be ready soon too.
Interesting. Pretty sure I saw a Truly Tropical Youtube at one point, and it was mentioned as a later season variety, but I could be mistaken.
So far it looks like Neelam, M-4 are the best options for extending the season by a decent amount beyond Orange Essence / Venus. Do they both flower and set fruit easily?
@Julie - from Rob's comments & others, sounds like Cotton Candy is a mid to late July and August fruit. M-4 is an August fruit, so M-4 should extend longer than CC. How it compares to Keitt - well that's a good question
Even so, M-4 I'm sure is superior in fruit quality.
