Triple-tested seed qualityRegular quality and germination checks support every packet.

We regularly test seed quality and germination as lots move through storage and packing. We stand behind the seed we send and want customers to contact us when a packet does not perform as reasonably expected.

1-year seed warrantyCoverage begins on the date of purchase.

When properly stored, planted, and cared for, we guarantee reasonable germination and true-to-type growth for one year from the date of purchase. Conditions outside our control—including extreme weather, pests, unsuitable storage, and gardener error—are excluded. Contact us when something is not right so we can review the situation and work toward a replacement, refund, or another fair resolution.

Non-GMO / BE seed policyWe do not buy or sell genetically engineered or bioengineered seed.

Every seed variety we sell is non-GMO.

USDA’s National Bioengineered Food Disclosure Standard defines bioengineered foods as containing detectable genetic material modified through in vitro recombinant DNA methods in ways not achievable through conventional breeding or found in nature.

  • Hybrid means parent lines were conventionally crossed; hybrid does not mean GMO.
  • Heirloom and open-pollinated describe how a variety is maintained and reproduced.

About this variety

What to expect from Pumpkin Spice Jalapeño Pepper Seeds

A pumpkin orange NMSU jalapeño with 22,000-25,000 SHU average reported heat.

Read the complete product descriptionTraits, flavor, garden use, variety notes, and the full catalog record

NuMex Pumpkin Spice is an NMSU-bred jalapeño selected for a distinct pumpkin orange mature color and a substantially hotter profile than a typical mild jalapeño.

NuMex Pumpkin Spice belongs to a three-cultivar group developed from a 1995 cross between Permagreen bell pepper and Early Jalapeño and released by NMSU in 2015. NMSU found its pods significantly longer than Early Jalapeño and reported little to no corking. The cultivar remains a Capsicum annuum jalapeño type; the color name should not be read as a flavor claim.

How to grow this pepper

Start indoors 6 to 8 weeks before the average last spring frost. Sow 1/4 inch deep in a clean seed-starting medium and hold the root zone near 85°F. Under suitable moisture and temperature, emergence is commonly expected in 7 to 14 days. Provide strong light as soon as seedlings emerge. Harden plants gradually and transplant only after frost danger has passed, soil has warmed, and nights are consistently mild. Grow in full sun in fertile, well-drained soil. Keep moisture consistent without leaving roots waterlogged. Space plants about 18 inches apart in rows 24 to 30 inches apart.

Harvest and use

Harvest green for the familiar immature jalapeño stage or leave pods on the plant until they mature pumpkin orange. NMSU reports 22,000-25,000 SHU reported across NMSU references as an average reference value. Actual pungency can shift with genetics, weather, water stress, and location. Use fresh, pickled, roasted, or in salsa wherever a hot jalapeño is appropriate.

Seed saving

Save seed only from fully mature fruit that has reached its final ripe color. Choose healthy, true-to-type plants and avoid saving from weak, diseased, or visibly off-type plants. Capsicum annuum varieties can cross through insect activity, so isolate flowering varieties or use blossom bags or pollinator-exclusion cages when varietal purity matters. Remove the seeds, spread them in a thin layer with good airflow away from direct heat and strong sunlight, and dry completely before labeling and storing them cool and dry. Save from multiple true-to-type plants when maintaining a population rather than merely saving a small household sample.

Variety-specific growing notes

The NMSU release summary focuses on mature color, pod dimensions relative to Early Jalapeño, corking, and heat. It does not provide a cultivar-specific plant-height or days-to-harvest value.

Practical field and garden tips

Pick green for the immature jalapeño stage. Leave pods on the plant for the named mature color and fully mature seed.
Harvest, storage, uses, and benefitsWhen and how to harvest, ways to use the crop, storage, culinary value, habitat value, and garden roles

Harvest and use notes

Harvest green for immature jalapeño use or wait for the final pumpkin orange stage. Save seed only from fully mature, true-to-type fruit and prevent crossing with other Capsicum annuum varieties when purity matters.

Uses and benefits

Use green or mature-colored pods fresh, pickled, roasted, or in salsa. Treat the cultivar as a hot jalapeño and handle cut fruit accordingly.

Problems and answersPests, diseases, troubleshooting, practical response, and product-specific questions

Variety troubleshooting summary

Watch for aphids, flea beetles, thrips, whiteflies, spider mites, and caterpillars. Common disease risks include bacterial leaf spot, Phytophthora root and crown rot, and virus complexes. Use clean transplants, avoid working wet foliage, rotate away from solanaceous crops when disease has been severe, maintain airflow, and remove badly affected plant material. Blossom-end rot is a calcium-transport disorder usually worsened by uneven watering rather than a simple lack of calcium in the soil. Sunscald is more likely when fruit lose leaf cover.

High heat levels can increase handling risk. Wear gloves when processing many ripe pods and avoid touching the eyes or face.

Questions gardeners ask

How hot is it?
NMSU reports 22,000-25,000 SHU reported across NMSU references. This is an average reference, not a guarantee for every pod or growing season.

When should I expect a harvest?
Cultivar-specific days to harvest are not stated in the NMSU release summary. Harvest timing varies by transplant age, weather, and color stage.

Does NuMex Pumpkin Spice taste like its color name?
Jalapeño-type flavor. The name describes mature color; NMSU did not report pumpkin flavor, baking-spice flavor, or unusual sweetness.

Can I save seed?
Yes, when the seed stock is open-pollinated. Allow fruit to reach full ripe color, prevent unwanted crossing when purity matters, dry the seed thoroughly, and label the harvest by variety and year.
