I agree, not suitable for a pot. If you can plant in the ground then make sure they don’t get swamped by surrounding plants because they can take 3-4 seasons to reach their full height. Also where the deep tap root is bad in a pot it’s a strength in the ground because virtually no maintenance is required. Just chop and drop the dead foliage in the spring and depending on the variety you may get seedlings.
Congratulations on your newly potted Eryngium 'Blue'! Taking good care of it from the beginning will ensure its health and growth. Here are some tips for good practice maintenance as per my experience.Initially, water the plant thoroughly after potting, allowing excess water to drain. Eryngiums prefer well-draining soil, so ensure the pot has drainage holes. Water when the top inch of the soil feels dry, but avoid overwatering, as it can lead to root rot.Secondly, Eryngiums prefer sandy or loamy soil with good drainage. You can use a cactus or succulent mix or create your own by mixing regular potting soil with perlite or sand to improve drainage. Thanks a lot
