Cerinthe major 'Purpurascens'
Artful gardeners are always on the lookout for
wonderful new plants to enliven beds and borders. Indoors or
out, arranging colorful combinations is greatly simplified when
we use quantities of long bloomers, plants whose good looks hold
for months on end. A recent returnee to the garden scene,
Cerinthe major 'Purpurascens', is exactly the sort of tireless
worker we need. Commonly called honeywort, this borage relative
offers handsome foliage and stunningly colorful bracts that long
outlast its small flowers.
Like its kitchen cousin, honeywort's flowers
are tubular bells of intense blue or purple, delicately
scalloped and lined in cream. The bells are clustered in twos
and threes, each group nesting inside brilliantly blue bracts
like overlapping fish scales. The true leaves are rounded like
grapefruit spoons, lustrously grey-blue
in color and as fleshy in texture as a succulent. The new growth
is strikingly stippled with creamy stripes and flecks which fade
to a subtle marbling as the leaves mature.
Although grown in European pleasure gardens
since the middle ages, Cerinthe has no known medicinal uses.
According to his famous book, 'The Herbal', its ornamental
qualities earned honeywort a place in John Gerard's garden in
the late 1500's. Gerard liked to sip honey-flavored
nectar from the tiny flowers, and noted that the leaves have the
taste of "new wax" or fresh honeycomb as well. Since his day,
however, honeywort fell from favor. It has never been a
traditional border plant, for no prominent Victorian or
Edwardian gardener mentions it. Indeed, it was unavailable in
the seed trade until the recent reintroduction of a well-colored
European garden selection.
Native to the Mediterranean basin, wild
honeywort displays a wide variation in color and form. Where
Cerinthe major grows abundantly in open meadows and grassy
plains in southern Italy and Greece, the flowers may be
lavender, cream or pale yellow, sometimes neatly rimmed or
striped with violet. The bracts may be a dull blue_green, soft
or vividly blue, or warmly purple. In early summer, Greek fields
of these common wildflowers are hazed with a pewtery slate blue,
like a shimmering reflection of the hot summer sky.
Seen as individuals in garden settings,
honeywort plants are enchanting. The partially perfoliate leaves
rise in whorls along branching stems which bend gracefully
beneath their burden of blossoms and bracts. Garden grown plants
vary a good deal in size and behavior. Those raised in lush,
sunny settings may rise more than waist high, needing
unobtrusive staking with twine and slim bamboo wands to keep
them upright. Rich, open-textured soil
and ample water make for an exceptional abundance of blossoms
and bracts which retain their handsome appearance well into
autumn.
In leaner, drier soils, plants grown in full
sun may only reach two feet in height, while those grown in
light shade and poor soil are generally compact and rarely over
a foot and a half high. Like so many Mediterranean natives, this
handsome herb is as drought tolerant as
rosemary, sage or thyme. Even when grown in unimproved, sandy
soils in full sun, honeywort will bloom early and often. Indeed,
in damp shade, this sun lover languishes and may rot away before
fulfilling its floral potential. However, honeywort makes a
fuller and far more floriferous mound when given ordinary
amounts of supplementary water.
The blue bracted honeywort will particularly
appeal to border colorists and flower arrangers, who are always
on the lookout for good blues. This plant is especially fun to
work with because it is a color changer, its bracts altering
from royal blues and cloudy purples to tawny coppers and ruddy
browns when backlit by slanting sun. Honeywort pairs
dramatically with purple hazel, which shows the same tendency to
crossover, its wide leaves shifting readily between mahogany and
burgundy depending on the light.
Honeywort also makes delightful company for
flaming crocosmias like sizzling orange 'Firebird' and fire red
'Lucifer', as well as smoky 'Salmon Leap' Cape fuchsias (Phygelius
x rectus). To emphasize its cascading lines, try placing it with
tall, arching grasses such as maiden grass, Miscanthus sinensis.
It also makes a splendid companion for ruddy, fox_colored Carex
buchananii or the bronzed forms of Carex comans and C. filifera.
To accentuate the murky color qualities of
honeywort's burnished bracts, interplant it with masses of
purple_bronze Euphorbia dulcis 'Chameleon' and near_black
chervil, Anthriscus sylvestris 'Ravenswing' or the pewtery
purple form, 'Moonlit Night'. The muted burgundy of shrubby
Hypericum androsaemum 'Albury Purple' will echo tints in all
this group of plants, rounding out the vignette with panache.
In certain parts of England, Cerinthe major 'Purpurascens'
is said to be solidly hardy and evergreen to boot. Elsewhere,
Cerinthe major is an annual, though the smaller, yellow-flowered
Cerinthe minor is considered hardy to zone 5. Here in the
Pacific Northwest, both commercial and home growers from
southern British Columbia to California's Bay Area have found
Cerinthe major 'Purpurascens' to be an ardently self-sowing
annual.
Like ordinary borage, honeywort comes readily
from its abundant seed. In the garden, however, the seeds tend
to sprout in the fall and be killed by the first sharp frost.
Because the seeds ripen irregularly, and because an explosive
release mechanism often propels them a considerable distance
from the mother plant, seed can be tricky to collect. One good
way is to check the ground beneath large plants every few days,
gathering small handfuls of the cylindrical black seeds as they
fall.
It is also possible to harvest whole branches
of blooming honeywort, bringing them inside to dry. Keep the
branches lightly covered with cheesecloth or newspaper to keep
the seed from shooting across the room as it dries. Although
many seeds will be unripe when you gather the branches, most
will ripen to maturity as the bracts wither.
To save honeywort seed over the winter, place
it in a clean, dry jar with a small packet of film dessicant. A
tablespoon of dried milk powder, loosely wrapped in a square of
cheesecloth, will similarly absorb moisture from the air,
keeping the seeds properly dry until spring.
