The Story of the Palmetto Corn Snake

Palmetto Corn Snake: Discovery, Genetics, and History

The Palmetto corn snake is one of the most unique and sought-after morphs in the corn snake hobby. Known for its stunning leucistic appearance with subtle flecking, this incompletely dominant mutation has captivated breeders and enthusiasts since its discovery.

In this detailed guide, we'll explore the origins of the Palmetto corn snake, its genetic inheritance, breeding history, market status, and why it's confirmed as a pure Pantherophis guttatus.

 

What Is a Palmetto Corn Snake?

  • Most Common Name: Palmetto (no known aliases)
  • Genetic Inheritance: Incompletely dominant mutation
  • Morph Type: Incompletely dominant to wild-type
  • Eye Color: Black pupil with dirty white or blue iris; some specimens show colored flecking
  • Mutation Type: A variant of leucism
  • Origin: Wild-caught adult male from South Carolina (2008)

The Palmetto corn snake stands out due to its clean, white base color with random dark flecking on the head and body. Unlike typical leucistic snakes, Palmettos often retain subtle patterns and head stamps that add to their appeal.

The Discovery and First Breeding of Palmetto Corn Snakes

In 2009, Don Soderberg of South Mountain Reptiles (SMR) acquired the world's first known captive Palmetto corn snake—a wild-caught adult male from South Carolina. At the time, this was the only Palmetto in captivity, and its genetics were completely unknown.

To preserve the mutation, Don paired the male with a receptive Amelanistic (Amel) female. Rather than risk shipping the rare male first, he sent the female to South Carolina for breeding. After confirmed copulation, the female returned to Texas, and the male was shipped safely afterwards.

This cautious approach paid off. The initial pairing produced heterozygous offspring (hets for Palmetto) in 2010. By 2012, breeding hets together and back to the original male yielded the first visual homozygous Palmettos.

Naming new corn snake morphs is tricky—most use colors, foods, or patterns (e.g., Candy Cane, Bloodred). But the Palmetto's appearance varies dramatically between individuals.

Don rejected descriptive names that might not fit all offspring. Instead, friends Daryl Camby and Jim Godfrey suggested Palmetto after South Carolina's nickname: The Palmetto State. This geographic name ensures it never "disappoints" visually and ties directly to the snake's origin.

Is the Palmetto Corn Snake a Pure Corn Snake?

Yes—here's the evidence:

Feature Palmetto Comparison Corn Snake (P. guttatus) Black/Yellow Rat Snake (P. obsoletus/quadrivittata)
Anal Plate Divided Divided Divided
Scale Keeling More like corn Keeled Variable, often stronger
Ventral Keel Larger radius (corn-like) Broad Sharper
Facial Scales Corn-shaped Corn-like More rat-like
Subcaudal Scales 70 (overlaps Black Rat, below Yellow) 60-85 Black: 63-90; Yellow: 75-102
Hatchling Size ~Half rat snake hatchlings Small Larger
Adult Size Never approaches rat snake length 3-5 ft 5-8+ ft
Temperament 95%+ gentle (corn-like) Typically docile Often defensive

Without DNA testing, 100% certainty isn't possible—but size, scalation, and demeanor overwhelmingly point to Pantherophis guttatus. The Palmetto is the first leucistic mutation in corn snakes with consistent flecking, unseen in North American rat snakes.


 

Palmetto Corn Snake Market History and Pricing

The Palmetto was carefully managed to maintain value and rarity:

  • 2010: First heterozygotes produced
  • 2011: Limited breedings (only 3 het females)
  • 2012: First visual Palmettos sold for $4,000 USD each (females only)
  • 2015: First males and heterozygotes released to the market
  • 2025: 15 years later Palmettos are priced from $200 to $600 depending on morph, with Scaleless Palmettos and Microscale reaching still into the thousands.

This controlled release prevented market flooding—unlike many corn snake morphs that quickly became common. Today, classic Palmettos still command premium prices, while combos with other morphs (e.g., Scaleless Palmetto, Lavender Palmetto) are even more valuable.

Palmetto Corn Snakes Today

Palmettos have been combined with dozens of other morphs, creating breathtaking variants:

Classic/Normal Palmetto: White with red/orange/gray flecks.

Anery Palmetto: Grayscale (black/gray flecks on white).

Amel (Albino) Palmetto: Brighter, with yellow/orange tones.

Blizzard Palmetto: Mostly pure white (amel + charcoal combo).

Caramel Palmetto: Warm caramel undertones, often patternless.

Scaleless Palmetto: Velvet-like texture, no scales (high-end, e.g., het amel at $3,000).

Ultramel Palmetto: Enhanced amel-like brightness.
