Growing and Maintenance Tips

Eryngium thrives in hot, dry sunny sites in soil that is well drained.  It tolerates poor soil. The plants will flop over in flower if they are grown in soil that is very rich or if they are watered too much. This is a tap rooted plant that resents disturbance and is best left to colonize on its own rather than attempting to divide it. It is tolerant of salt.
