Eryngium 'Jade Frost' Sea Holly



Eryngium 'Jack Frost' is a stunning variety of Sea Holly with variegated green and cream, thistle-like foliage. Striking violet-blue flowers bloom on well-branched stems from June to August.

'Jack Frost' Sea Holly performs best in dry to average soil and full sun. It can tolerate clay soil, coastal conditions, and drought. Choose its location carefully, as its long tap root makes it difficult to transplant.

An excellent variety for floral arrangements - just cut the stems before the flowers are fully open and allow to dry. Bring Eryngium 'Jack Frost' Sea Holly to your garden!

We ship via UPS & USPS (the Post Office), and their ship rates are automatically generated through our site. We do not profit on shipping costs. We are working with these providers to get our customers the best rates possible.

All ship times are subject to change if extreme weather conditions are present here at the nursery or at the shipping destination.

Please note: Depending on the time of year, the foliage of the plants may be trimmed to fit into our shipping boxes. This could delay the flowering of the plant, but many perennials actually benefit from being cut back.

We are currently not able to ship to Puerto Rico, Hawaii, and outside of the US.
