Blue Sea Holly Growing and Maintenance Tips

Grows best in a dry, sandy, well-drained soil, in full sun. Has a large taproot and once established, does not like to be moved. Eryngium may need staking and lose some of their colour if planted in soils that are too fertile or shady. Plants do not spread or produce viable seed.
