Botanical Nerd Word: Epigeal germination

Epigeal germination: Seed germination in which the cotyledons (seed leaves) are raised above the soil surface.*

These arugula seedlings raise their heart-shaped cotyledons above the soil surface to begin photosynthesis before their first true leaves appear. Many plants germinate in this way, for example, beans and sunflowers.
