Culture
Easily grown in dry, sandy, well-drained soils in
full sun. Tolerates poor soils. Tall plants may sprawl, particularly if
grown in overly fertile soils or in anything less than full sun. Avoid
overwatering. This is a taprooted plant that transplants poorly and is
best left undisturbed once established. Plants will slowly spread in the
garden over time.
'Blue Hobbit' May be grown from seed. Plants will slowly spread in the garden over time.
Noteworthy Characteristics
Eryngium planum, commonly called sea
holly, is a coarse, clump-forming perennial that features a summer bloom
of steel-blue, thistle-like flower heads on branched stems rising from a
rosette of dark green basal leaves. Basal leaves (typically elliptic to
oblong, cordate-based and deeply-toothed) form a rosette to 6" tall and
to 14" wide. Stiff, branched, violet-blue stems (to 32” tall), bearing
abundant, egg-shaped, thistle-like, violet-blue flower heads, rise from
each basal rosette in summer. Each flower head is a
spherical-cylindrical umbel that is packed with tiny, stemless,
violet-blue flowers. Each flower head is subtended by a narrow, spiky
collar of spiny, blue-green bracts. Summer bloom is often profuse.
Genus name comes from an ancient Greek name used by Theophrastus for a plant which grew in Greece (probably Eryngium campestre) or is a Greek reference to the prickly or spiny nature of plants in this genus.
Specific epithet means flat.
‘Blue
Hobbit’ is a dwarf sea holly that rises in a globular mound to only
8-12" tall when in full bloom. Spiny, egg-shaped, purplish-blue flower
heads atop silver-blue stems appear in a profuse and long summer bloom.
Cultivar name of Hobbit is in reference to fictional characters created
by J. R. R. Tolkien.
