Eryngium

Sea Holly

From its leathery lobed leaves to the spiny decorative bracts that host the flower, the dynamic Sea Holly has a sense of movement that is up and out. Excellent in fresh or dried arrangements, the flowers are borne on tall branching stems, and the terminal blooms hold their color while lateral flowers develop, until the entire stem is covered with mature blossoms. Eryngiums love sharp-draining soil in the open sun, and are an arresting ad­dition to the mixed border, especially when planted amidst Rudbeckia, Achillea and grasses.

This cold-hardy species yields up-curving bracts that are long spiny slivers of silver plus thistle-like metallic-blue blossoms, surmounting branched stems that are tinted blue on their upper extremities. Marked with a smattering of mercury-hued speckles and white veining, deeply cut, gray-green leaves make a low-lying rosette for the unique floral phenomenon.

Blooms July–September

Size: 2' 0" high x 18" wide.

Hardy to zone 4.

Looking for more botanical inspiration...

and who isn’t on a chilly mid-January day? I certainly was, as I strolled through the nursery and garden with a steaming mug of Oolong tea and my trusty canine companion, Boobah in tow. Almost immediately I was pleasantly surprised to spot the Hellebores. Bejeweling the winter garden, their marvelous single or double-petaled blooms yield an array of colors that include chartreuse, sparkling white, pink, smoky plum, and a rich nearly black maroon. Apart from the Hellebores, I came upon the plump berries, glistening evergreen foliage and winter flowers that are featured in this newsletter. We hope you find a healthy dose of January cheer!

All of us plant wranglers at the nursery, along with Boobah, our wee greeter and self-appointed nursery manager, and shy kitty, Parker, wish you countless happy hours digging in a garden of your own!
