Quick Answer
To identify seeds from different heirloom varieties, examine the seed coat color, shape, and size, as well as the seed's overall texture and any visible markings or patterns. Compare these characteristics with known varieties and consult seed catalogs or expert resources for confirmation. Consider using a magnifying glass or microscope for closer inspection.
Examine Seed Coat Color and Shape
Examine the seed coat color, which can be a good indicator of the variety. For example, some heirloom tomatoes have red seeds, while others have yellow or brown seeds. The shape of the seed can also be distinctive, with some varieties having elongated or pointed seeds. Measure the seed’s width and length to compare it with known varieties. Typically, a small sample of seeds from each variety will yield a consistent size range.
Look for Visible Markings and Patterns
Heirloom seeds often have unique markings or patterns on the seed coat, which can help with identification. For example, some varieties have small ridges or bumps on the seed surface, while others have distinctive stripes or spots. Examine the seed under a magnifying glass or microscope to reveal any subtle markings. Make a note of the pattern and compare it with known varieties.
Record and Compare Seed Characteristics
Keep a seed record book or spreadsheet to track the characteristics of each variety. Record the seed coat color, shape, and size, as well as any visible markings or patterns. Compare these characteristics with known varieties and consult seed catalogs or expert resources for confirmation. Consider creating a seed identification key to help with future identification.
