Eryngium

Sea Holly

Dynamic is a rare adjective to apply to a plant, but it’s the best we can think of to describe Eryngium. From its leathery lobed leaves to the spiny, decorative bracts that host the flower, the 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 well drained soil in the open sun, and are an arresting addition to the mixed border, especially when planted amidst Rudbeckia, the Achilleas, and grasses.

A snowy white multitude of plump conical flower heads perch atop pointed, widely spaced silver bracts. Leafy multibranching stems, pearly hued and steadfast, bolster the luminous blooms, while arising from an attractive dark green basal rosette defined by serrated leatherlike leaves and red-tinted petioles. Pair ‘Silver Salentino’ with Eryngium ‘Blue Glitter’ for a classic look.

Blooms July – September.

Size: 2-1/2'–3' high x 15"–18" wide; hardy to zone 4.

Current Staff’s Favorite Plant

This glamorous beacon for the late season garden is our favorite plant this week. Hydrangea aspera ‘Rocklon’ with it's large pink clouds of buds and pinkish bronze, downy new growth bring a soft look to this noble, rarely cultivated Hydrangea. Mounted on stout fuzzy stems, wide, hairy serrated foliage, with red-hued petioles, provides a graceful deep green foil for the enormous mauve lacecaps ringed by white bracts. Adequate water and bright shade will ensure ‘Rocklon’s prosperity, while Corydalis and Stylophorum diphyllum offer contrasting texture beneath. (S-0421)
