Corn 'Signature XR'
F1 Hybrid
Zea mays
Over the years, we’ve grown many varieties of sweet corn, but Signature XR is by far our favorite—offering some of the finest eating quality available today! This early-midseason bicolor variety delivers a tender, deep bite with exceptional flavor. It boasts great tip fill, excellent husk cover, and snaps cleanly off the cob, plus it has a long shelf life. It’s probably Matt’s favorite summer vegetable, and we love enjoying it grilled fresh on the cob!
Packet contains approximately 100 seeds.

How to Grow
Seeds need a minimum soil temperature of 65°F. Sow 3/4–1" deep, 6-7" apart (or 2 seeds every 9", thinning to 1 plant), rows 30–36" apart. Arrange in blocks of at least 4 rows for proper pollination, which is needed for well-filled ears.
Harvest & Storage
Once established, harvest leaves before flowering begins. Leaves can be harvested 3–4 times per year, cut at ground level. Leaves may be used fresh or dried. To dry, cut bundles into 1/4–1/2" lengths. Dry on a screen surfaced out of direct sunlight in an area with good ventilation. Stir periodically.
Hybrid Seeds (Never GMO)
Please note that hybrid varieties are produced by traditional breeding methods of two distinct OP (open-pollinated) varieties within the same species. This is done for improved qualities, but saved seeds will not produce true to seed. While I tend to prefer most OP varieties, there are some exceptions in which a hybrid is a real winner (like my favorite cherry tomato, Sungold).
It's important to note that this is entirely different from genetic modification. Genetically Modified Organisms (GMOs) have DNA (sometimes from non-plant organisms) inserted into their genome via genetic engineering techniques.
We do not sell GMO seeds.
From Johnny's: F1 Hybrid seeds are the result of a cross between two genetically distinct parent plant lines. The plants grown from these seeds will usually show more vigor than either of the two parent plants, and often more vigor and uniformity than similar non-hybrid (standard) varieties. To create a hybrid (F1), traditional breeding methods are used that involve the cross-pollination of two parent varieties that were selected for specific traits.
