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.
Smelling like a carrot, looking
a bit like a Yucca and once
used by pioneers and Native
Americans as an antidote
to rattlesnake venom, this
American tall grass prairie
dweller brandishes bold
bluish green lax rosettes.
Characterized by parallel
veins, bristly edges and a
glaucous finish, the 3 ft. long
sword-shaped leaves launch
an architectural wonder of
tightset thistle-style greenish
white spheres and pointed ivory bracts housed
within branched clusters on smooth stiff stems. A low
maintenance perennial that provides fantastic winter
interest, Rattlesnake Master obliges dry rocky soil and
can be planted amid softer textured grasses such as
Eragrostis chloromelas or Pennisetum spathiolatum.
Size: 3' 0"–4' 0" high x 18"–2' 0" wide; hardy to zone 3.
Eryngium yuccifolium (P-1632)
