Quick Reference

Zones

Plant Hardiness Zones describe the average minimum winter temperature for a region. They tell you where a plant can reliably survive outdoors. For example, Zone 5 can handle colder winters than Zone 9. Matching a plant to your zone increases the chance of long-term success.

Days

  • For food crops: Days to maturity is the expected number of days from planting to first harvest. This helps gardeners plan their growing season and time their harvests.
  • For non-food plants: Days to germination indicates how long it usually takes seeds to sprout under normal conditions. This is key for starting seeds successfully.

Types

  • F1 (Hybrid): A cross between two parent varieties. Hybrids are bred for vigor, uniformity, and specific traits such as disease resistance. Seeds saved from F1 plants don’t grow true to type. That means if you try to regrow them from seed, the plant won't necessarily be the same as last year's
  • OP (Open-Pollinated): Varieties that naturally pollinate and remain stable across generations. Seeds can be saved and replanted with consistent results.
  • HM (Heirloom): An open-pollinated variety that has been handed down for many generations. Heirlooms are valued for flavor, tradition, and genetic diversity.

Grows

  • Outdoors: Well-suited for garden beds, raised beds, or open soil, where natural conditions are stable.
  • Windowsill: Compact plants that thrive in containers indoors, often needing only modest light.
  • Anywhere: Highly adaptable plants that perform reliably in both indoor and outdoor settings.

Lifecycle

  • Annual: Grows, flowers, sets seed, and dies in one growing season. Many vegetables and flowers are annuals.
  • Perennial: Lives for multiple years, regrowing each season after going dormant. Often used in landscaping or long-term food crops.
  • Sp. Perennial (Self-Perennializing): A plant that reseeds itself or self-pollinates, giving the effect of perennial growth even if individual plants live shorter lives.

Size

Indicates the recommended container size or soil depth for best growth.

  • “X″ Pot”: The ideal pot diameter (e.g., 5″ Pot), ensuring enough root space.
  • DS (Deep Soil): Requires planting directly in the ground or in a deep raised bed, as shallow pots restrict growth.

  • Distinctive Taste & Texture: Produces 25 cm long cobs with 14-16 well-filled rows of ultra-sweet kernels that maintain sweetness post-harvest, offering a 'crunchier' texture compared to other varieties.
  • Growth Conditions: Thrives in warm soil at least 15°C (60°F). Plant seeds 4 cm deep and 30 cm apart in rows 1 m apart. Prefers well-fertilized soil and requires frequent shallow cultivation due to surface-level roots.
  • Extended Sweetness: Reaches maturity in 75 days, with a remarkable ability to retain its sugar content longer than typical corn, making it perfect for preserving by freezing while retaining flavor.
  • Culinary Flexibility: Ideal for fresh consumption straight off the cob, grilling, or using in salads. Excellent for freezing, ensuring year-long availability for gourmet dishes.
  • Isolation Requirements: To maintain purity and optimal sweetness, ensure to plant this SH2 variety at least 30 meters away from other corn types to prevent cross-pollination.

Experience the exceptional sweetness and crunch of Early Xtra Sweet SH2 Corn in your own garden. This variety is known for its ultra-sweet kernels that increase in sweetness post-harvest, making it an ideal choice for fresh consumption or freezing. Plant after the last frost in warm, well-fertilized soil, and enjoy a bountiful harvest in just 75 days.

Early Xtra Sweet SH2 Corn offers remarkable versatility in the kitchen, perfect for grilling, boiling, or adding to salads.

  • The 500-seed packet suits larger backyards or community gardens planning multiple short rows or staggered sowings. It provides enough seed for steady harvests over several weeks.
  • The 2500-seed packet is a strong fit for small farms, market growers, or school gardens establishing multiple beds. Enables reliable block plantings for uniform ears and consistent market supply.
  • The 10000-seed packet is best for commercial growers, CSAs, or u-pick operations targeting extended harvest windows. Supports large-scale, succession-planted blocks for volume production and freezer-ready yields.
GROWING INSTRUCTIONS

Sow Early Xtra Sweet SH2 Corn seeds outdoors after the last frost when soil temperatures reach at least 60°F (15°C). Plant seeds 1.5 inches deep and 12 inches apart in rows spaced 36 inches apart for optimal growth. Ensure the planting area receives full sun and is well-fertilized.

To germinate, keep the soil consistently moist. Corn is wind-pollinated, so plant in blocks of at least four rows to ensure good pollination. Once seedlings emerge, thin them to maintain 12-inch spacing. Harden off seedlings before transplanting if starting indoors.

Provide regular watering, especially during dry spells, and use a high-nitrogen fertilizer every 10 days. Be cautious with shallow cultivation to avoid damaging surface roots. Harvest when the silk turns brown and the kernels are plump. Enjoy fresh, or preserve by freezing for later use.
