Costco's Heirloom Pumpkins are a beloved seasonal staple, sold individually and available in an assortment of unique colors, shapes, and sizes. Unlike standard round orange jack-o'-lantern pumpkins, these heirloom varieties feature distinctive tones including muted gray, blue-gray, creamy white, soft pink, and deep orange, with textures ranging from smooth to heavily warted. Popular varieties include the flat, blue-green Jarrahdale, the peach-hued Porcelain Doll, and bumpy sugar-wart types known for their striking appearance.

These pumpkins are prized for their decorative versatility and are a go-to fall essential for Costco members each October. Their squat profiles and naturally varied silhouettes make them ideal for tablescapes and centerpieces, where they won't obstruct sightlines across a table. They display beautifully on front porches, in entryways, and as part of autumn vignettes. Since each pumpkin is naturally unique, no two look exactly alike, adding genuine heirloom charm to seasonal decor. They can be dressed up without carving using paint, stickers, or simple embellishments.

Many heirloom varieties are also fully edible. The heavily warted types are particularly prized for their sweetness when roasted or baked. Heirloom pumpkins of this quality are rarely available at conventional grocery stores or big-box retailers, and when found at roadside stands they typically command a premium over Costco's per-pumpkin price.
