I love this time of year in the garden when it is not quite
spring, but winter is loosening its grip. Days lengthen, the sap rises, and the
bluebirds return to build their nests. Not much is blooming yet: just the
daffodils and the frost-proof cups of cream and pink that grace the hellebores.
The trees have not leafed out. And yet, for a gardener, it's as exciting a time
as the build-up to Christmas morning. So much is promised. Possible. Palpable.

| Dreaming of the iris in bloom... |
Some of the best markers of growth in this season as the
equinox approaches are the iris. Spurred by weeks of heavy rainfall the green
blades of Siberian and Japanese iris have begun thrusting their knife-points
free of the dead foliage at their crowns. Vigorous stands of swamp-loving
Louisiana iris never shed their green foliage, not even through the coldest
part of the season, nor does a wildly vigorous stand of the native blue flag iris, I. virginica, which I planted in standing water at the low spot
beside my garden shed. But now the growing stalks brighten and glow as if
flames are burning inside them, with the virginica
and the Socastee river iris selection,
I. versicolor 'Swords of Murex,' sporting
purple-stained blades at the base.

Most of the beardless iris species I grow
are water-lovers, including the exceedingly rare and beautiful Foxcroft Full
Moon, a white I. pseudacorus with violet stitching on the falls. In addition to needing moisture, beardless iris
must have acidic soil to perform well, with a pH no higher than 6.5, and
Carolina clay is made to order. In this respect the beardless iris are the
complete opposite of bearded iris (I.
germanica) which require dry conditions and alkaline soil, preferring a pH
of 7 or above.
 |
| Iris sibirica blades emerging in spring. |
I grow a few cultivars of tall bearded (TB) iris in a plot inspired by British gardener Beth
Chatto's gravel garden. The TBs are slower to show new growth than the
beardless ladies, but in late March the blades will begin to thicken as flowerbuds
swell in their protected sheaths. The TB bed is exposed to full sun all day
(one aspect of their cultural requirements that they share with most beardless
iris).
 |

It slopes slightly to encourage sharp drainage, and is amended with lime
and mulched with gravel to keep the soil sweet and prevent the rhizomes from
rotting. This is not an easy task in our humid climate, and it may be why I
have lost so many of the pretty little dwarf varieties that never rise very far
above the damp soil. I have sworn
the dwarfs off but for the blushing beauty, 'Chanted,' which is still clinging to life.

Not to worry. In some years, starting in early April and
continuing through May, I get a splendid display of blooms from the few tall
workhorse varieties I keep on: 'Lemon-Lime,' 'Afternoon Delight,' 'Gypsy
Dancer,' and a glamorous iris passed along from a gardener at my former church,
ironically named 'Wench.' (The iris, not the church lady.) For the most part, however, the TBs resent
sharing space with the other plants in that bed: the roses, peonies, and
daylilies. As far as TBs are concerned, paradise is a dry, empty field occupied
entirely by their own kind. I can't offer them the space and exclusivity they
desire.
 |

A chummier species of iris is I. tectorum, or roof
iris. 'Alba' blooms in mid-April at the foot of my variegated Japanese maple, Acer palmatum 'Beni-schichihenge.' These
clumping iris happily rub shoulders in the filtered light beneath the tree with
wild columbines, bugleweed and a cherished, small-leaved Buxus microphylla started as a cutting from a boxwood in writer
Elizabeth Lawrence's Charlotte garden.
 |
| Iris tectorum 'Alba' appreciates the shade of trees. |
Here's the hallmark of an excellent garden
plant: I've divided the patch of tectorum
many times and it never complains.
Nor do my beardless iris
pile on much agony. The consistently cold weather we experienced last winter
had a positive effect on the Siberian
iris cultivars I grow, as well as my southern peonies; both species of
plants need a certain amount of cold dormancy to do well, and they got it. People
unfamiliar with South Carolina's upstate region are always surprised when I tell
them how cold our winters can be, especially here on our little mountain above
the Spartanburg plain.

In the ten years we've lived in Traveler's Joy, we have
never had a snow-free winter, and have occasionally endured single-digit
freezes. (That doesn't mean we don't get hot summers… Lord help! Equatorial.)
Benefiting from the deep-freeze, a small plot of I. sibirica 'Sparkling Rose' that I'd
planted and forgot about a few years back suddenly threw out a multitude of fat
budstalks last spring. When the flowers bloomed in April, they were dazzling.
 |
| I. sibirica 'Roaring Jelly.' |
It was the same for I. sibirica 'Roaring
Jelly,' and a clump of I. sibirica
'Ever Again,' a hybrid introduced by iris grower Currier McEwen. The latter grew
so vigorously in its first year in my garden that by the second year I was able
to take a piece of it to share with my daughter in her Raleigh plot. I bought
this three-gallon pot of 'Ever Again' at the farmers' market in nearby Cowpens
from a member of the Spartanburg Men's Garden Club for the remarkable price of
$5. I told him it wasn't enough, but he argued back that it was the end of his
day and he was ready to be done with the pots and go home. I've longed to
return to the market and buy more plants now that I've seen these iris perform,
but the farmers market never reopened after that spring. Cowpens mayor, are you
listening?

The Siberians get their bloom going in late April or early
May. Following them in the iris blooming cycle are the Louisiana irises. Modern hybrids of these swamp-lovers sport
flowers in all the colors of the rainbow, but I take most pleasure in those
with the wild Iris fulva as one of
their parents. The warm terra-cotta tones of fulva aren't seen in other beardless iris, but they are glowingly apparent
in the stand of I. louisiana 'Red
Dazzler' which grows in my rain garden.

These dark red flowers are sensational
blooming against a background of Loropetalum
'Red Diamond,' and dragonflies love them. Also, they remind me of a gardening
friend who taught me a good deal about iris and who has since passed away. I
think of Dawn and smile when the dazzlers bloom.

Japanese iris, I.
ensata, close out the iris season with a grand finale. They are tall and
dramatic, with flowers spread like flashy handkerchiefs atop the stalks. I grow
I. ensata 'Wilderness Warrior' in a
spot where she is protected by Itea 'Henry's Garnet' and an old-fashioned
pillar rose, 'Souvenir du Dr. Jamain'; otherwise my pair of rescue dogs would
flatten the stalks and the beautiful mauve and white flowers along with them. My
favorite ensata cultivar is 'Nikko,'
a stunner in the sunny May garden with broad, marbled blooms of purple and
white featuring bright yellow signals.
 |
| I. ensata 'Nikko' in my garden. |
In addition to the showier types of Japanese iris, I grow a
species-type ensata which may or may
not be I. ensata 'Emotion.' I've
moved it so many times, once across state lines and then several times within
this garden, looking for the best site to show off its graceful, elongated
falls of deep, marine blue. It seems to be happy now in its sunny bed beside
the blueberry shrub, where Holly-Tone satisfies the needs of both fruit and
flower, and where the irises amplify the color of the ripening fruit.

I've bought a couple of different cultivars from Walter
Hoover, the Japanese iris specialist who owns Charles Street Garden in Saluda,
NC. He and his wife are among the dozens of excellent nurserymen and women who
bring their wares to Hendersonville's annual Garden Jubilee. I wouldn't miss
the show for anything, except a book event, and one of those kept me from
attending on Memorial Day weekend last year.
 |
| I. ensata 'Carol Johnson' |
I swore I'd not miss another
year's jubilee, but then I discovered that the Swan Lake Iris Garden in Sumter,
SC, which I've longed to visit for their iris festival held when the ensatas bloom, is being held on the same
weekend. May, to a gardener, is an embarrassment of riches.

Anyone who has read my fiction knows that I'm heavily
influenced by Greek and Roman mythology. For that I credit my Duke-educated
teacher of freshman high-school English. How that long-suffering man ever found
his way to our confederacy of dunces in the trackless wilderness is a mystery,
but I'm grateful he did. Mr. Rumsey started us on Camus, bless his heart, but gave
up after two weeks, collecting all our unread copies of The Stranger and replacing them with his own mimeographed pages on the
pantheon of gods and goddesses on Mt. Olympus. We ate up those bawdy tales of
vanity, passion and vengeance like they were Junior Mints -- I even wrote a comic
skit about Zeus and his jealous wife Hera that was performed by my bolder classmates.
 |
| Hera and Iris. |
I remember being fond of the minor goddess, Iris. She, along
with Hermes, were the gods' messengers, but while Hermes used his winged heels
to fly between Heaven and Earth, Iris traveled only on rainbows. Anyone who has
seen a field of bearded iris in bloom or watched dragonflies landing on a stand
of purple Siberian iris flowering in a pond will appreciate how appropriate
this symbol is.
In one of the few myths involving Iris, the messenger is
enlisted by Hera to help a young queen named Alcyone, whom Hera pities. Alcyone
and her husband, King Ceyx, shared a great love for one another and couldn't
bear to be parted. Howevr, Ceyx decided he had to consult the oracle in Delphi
about some knotty matter of state and so left his queen behind as he set off
across the sea. Naturally, since this is a Greek story, it ends in tragedy: the
king's ship is swamped in a storm and everyone drowns, Ceyx included.
Meanwhile, Alcyone is home in their kingdom, praying and making sacrifices to
Hera for her husband's safe return. This is why Hera orders up a dream for the
clueless widow, as the goddess can't bear to witness Alcyone continuing to hope
and pray that her beloved will come home. Iris dresses in her cloak of many
colors and travels down the rainbow to the Vale of Sleep, instructing the god
of slumber to craft a dream and send it to Alcyone, showing her how her husband
died.
 |
| Alcyone discovers her husband's drowned body. |
The day after her dream, the queen goes to the shore and sees
her husband's corpse washing in on the tide. She leaps into the sea,
planning to die alongside him, but here the gods intervene (and the question
is: why didn't they intervene earlier and save Ceyx??) They turn Ceyx and Alcyone into kingfisher birds and allow them to fly together over the waves.
In
Greece, the kingfisher female lays her eggs on the beach in winter, doing this
only during the seven to ten day period when the winds are calm and the seas
quiet, permitting her to nest atop the eggs. This calm, happy period in winter
came to be called Halcyon Days, in honor of the devoted queen.

For gardeners, this is our season of halcyon days, almost
better, in its way, than the full-blown flummery of May. All our devotion
through the cold, dark days is being rewarded with color and growth. With
beauty. All that seemed dead is coming back to life.
Can one hope for anything
better than that?
