Is isolation needed on Triplesweets when grown with Supersweets? The descriptions for the Triplesweets usually say "TripleSweet corn actually contains TWO kernel types, selected and reselected to create an ear that is 75% sugary-enhanced and 25% supersweet. Ideal for home gardens, it needs no isolation from other corn..."

But usually Supersweets say they must be isolated from other corn... all others or just su & se?

I wanted to grow Honey Select and How Sweet It Is, just feet away from each other. Honey Select (79 days) is the Triplesweet and is yellow, H.S.I.I. (87 days) is the sh2 and white.

I'm not worried about getting bi-color ears but I don't think I can wait an extra week or 2 to delay planting of the sh2 white to time isolation. I would even plant the later white upwind of the earlier yellow if it matters. Would it matter?

Is the statement about no isolation needed of the Triplesweets true in regards to not ending up with starchy field corn type results, and can TS & sh2 coexist without problems?

Thanks.
