Fresh sweet corn is the home gardeners candy!
Nothing can match the flavor of fresh-picked from your own garden.

But what do those letters, like SU and SH2 really mean?

Here's our quick guide to understanding sweet corn:

Highest sugar content. Superior tenderness. Just picked flavor lasts over a week in the fridge. No isolation needed.

(Sh2) Supersweet Hybrids
Snappy crisp texture and ultra-sweet flavor that lasts 4-6 days in the fridge. Must separate from other non-Sh2 types by 100' or 10-14 ripening days, to prevent cross-pollination.
Silver Queen Hybrid

(SU) Normal Sugary Hybrids
The "SUs" are the modern hybrids that revolutionized sweet corn in the mid-20th century, offering high yields and fresh flavor. No isolation needed.
Golden Bantam (Heirloom)
