All of the above +,Resist rain while ripening,way better than most others,included ,Ronde or Violette.
Also,They are not late ripening, on east coast,if you plant them in a totally ,full sun position,or grow in pot again,in totally full sun position.
In full sun they will start getting ripe on September 10.
Now ,there are some requirements to get ripe fruits early on late cultivars:
If in pot,grow the plant in one trunk type only and pinch after 5fth leaf.
If in ground leave three trunks or less coming from ground,remove all others,and also pinch tips after fifth leaf.
If you leave a multitude of trunks ,they will shade one another and no ripe fruits will be thy results,on September 10,and then you will also call me a lair, LOL!
