The sea hollies put on quite a show every June and July and this selection, by far, has been one of the most outstanding ever introduced to the Pacific Northwest. While many Eryngiums sulk and flower poorly in our mild and often wet Pacific Northwest conditions, ‘Sapphire Blue’ not only holds up under these conditions, it actually flowers prolifically in full blazing sun and dryish conditions once it is established making it quite drought tolerant and relatively carefree.
