Eryngium ‘Big Blue’
at Digging Dog


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.

This hardy Eryngium is big on blue—the electrifying, iridescent kind that promises to tantalize any garden visitor. A Blooms of Bressingham introduction, ‘Big Blue’s green spiky foliage and thick stems create an intriguing candelabra-shaped base for the bright 4 in. wide inflorescences. A blue drama is yours for the viewing as silvery white bracts and green cones, over the course of several weeks, gradually transmute amazing cerulean shades, imbuing even the stalks below.


Blooms July – September.

Size: 2'–2-1/2' high x 15"–18" wide. Zone 4/5.

Current Staff’s Favorite Plant

staff favorite plant

Our favorite plant this week: We love Tricyrtis 'Empress' for its unique, late blooming flowers. Renowned for its extra large and wider open flowers, this exquisite, newly introduced Toad Lily is a formosana hybrid. Ornate, spidery spaced petals are inscribed by occasional darkened tips and irregular velvet-rich deep purple spots, stipples and mottling on a creamy white background. An enticing fall beacon amongst the shadows, ‘Empress’s showy terminal blooms are supported by an upright robust gathering of lustrous, semi-clasping dark green foliage that stays dapper all season.
