I want to try to grow eryngium (seaholly) from seed this year. Is there any thing special I should do to make sure the seeds germinate? |
The seeds of Erynguim need to undergo a stratification process before they'll germinate. It's easiest to plant the seeds outdoors in autumn and let winter rains and frost achieve this, but you can subject the seeds to an artificial stratificationby soaking them overnight and then spreading them on a damp paper towel, placing them in a plastic bag, and putting them in the refrigerator until spring. Plant the seeds where you want the plants to grow because they resent being moved once established. |
