I normally grow White Out Sweet corn (https://www.2bseeds.com/sweetcornwhiteout.shtml), which is an SE type. It's quite sweet even after a few days in the fridge, and fairly productive.
But this year I noticed a new variety, Burpee's "Triple Crown XP" Sweet Corn. Apparently it's a fairly new (se/sh2) variety. Would that mean I have to make sure it doesn't cross pollinate with the SE variety? Is it tough and productive?
