Seed Germination Basics: Breaking Dormancy and Easy-to-Grow Seeds

Seed Germination Fundamentals

Seeds need oxygen, moisture, then light, proper soil, and temperature to grow. Each species has unique requirements. Tropical-origin seeds need warmth and moisture; mountain natives may require cold stratification.

Breaking Dormancy

Moisture alone often breaks dormancy (think sprouting seeds for salads). Some seeds need special treatment:

• Stratification: Cold, moist period for seeds like milkweed, columbine, daylily, monkshood, primrose, and rose.
• Scarification: Nicking or sanding hard seed coats (moonflower, camellia, holly, tree peony, wisteria).

Most seeds have an optimal germination temperature; many need warmth. Soak perennial seeds overnight (max 24 hours) to speed germination.

Easy-to-Germinate Seeds

• Vegetables: Beans, broccoli, Brussels sprouts, cabbage, cauliflower, celery, collards, eggplant, kale, kohlrabi, lettuce, onion, pepper, tomato.
• Herbs: Basil, chamomile, chives, cilantro, dill, fennel, oregano, sage, sorrel, summer savory.
• Annual flowers: Calendula, celosia, dianthus, marigold, nasturtium, pansy, petunia, salvia, snapdragon, sunflower, sweet pea, vinca, zinnia.
• Perennial flowers: Columbine, coreopsis, purple coneflower, Shasta daisy, viola.

Seed Starting

Start indoors and transplant, or direct-sow when soil is warm. Always check seed packets for specific needs. Learn propagation basics and get seed-starting essentials.
