Eryngium questions

Can Eryngium be grown from seed?
Yes, Eryngium can most certainly be grown from seed. Sow the seeds in well-draining soil, keep them moist, and provide adequate sunlight for germination. Keep in mind that germination can be erratic (between 5-90 days) and there is a chance that Eryngium won't flower the first year.

Can eryngiums be grown in pots?
Yes, eryngium is well suited to be grown in pots, planters and containers. Choose a pot with at least 30-45cm in diameter and depth and make sure there are drainage holes. 

Can you dry Eryngium flowers?
Yes! To dry Eryngium flowers, harvest them when they are fully open but still firm to the touch. Remove any excess leaves from the stems and hang the flowers upside down in a dry, well-ventilated area away from direct sunlight. They might take several weeks to dry completely (depending on humidity levels).

How long do eryngium seeds take to germinate?
Ah, the question we all want to know, experienced gardeners and professionals alike! Eryngium can be quite erratic in its germination rates. Generally, you will see sprouts after 7-21 days but sometimes they take their sweet time and can take up to 60 days. Please be patient with them!

Where is the best place to plant eryngiums?
Eryngium develops an extensive root system and don't like to be transplanted. For this reason, the best place to plant eryngiums is in the location that they will be able to remain undisturbed. They need a spot with well-draining soil and at least 6-8 hrs of sunlight a day. They are drought-tolerant once established.

Can you take cuttings from Eryngium?
Yes, you can propagate Eryngium by taking cuttings. The best time for this is in late spring or early summer when the plant is actively growing. Cut the stem just below a leaf node and remove the lower leaves. Dip the cut end in rooting hormone to encourage root development (not absolutely necessary). Plant the cutting in a well-draining soil mix and keep them moist until roots develop.

How do you collect Eryngium seeds?
Wait until the flower heads have dried on the plant (usually in late summer or early fall). Cut the dried flower heads from the plant and place them in a paper bag or envelope. Allow the flower heads to further dry indoors for a week or two. Once dry, gently shake or rub the flower heads to release the seeds into the bag or envelope. Store the collected seeds in a cool, dry place until you are ready to sow again.

Replant the divisions at the same depth as the original plant. Stem Cuttings: Cut a section of stem below a leaf node. Remove the lower leaves and dip the cut end in rooting hormone. Plant the cutting in a container filled with well-draining potting mix. Keep the soil consistently moist and provide indirect sunlight. After several weeks, roots should develop, and you can transplant the rooted cutting into the garden or a larger pot.
