Few gardeners can resist
the siren call of flowers. Perhaps at no time of the year are they more welcome
than when they signal the imminent arrival of spring. Just when we think we
can’t take another week of icy rain and dark skies, early spring blooming bulbs
appear bringing color, fragrance, and even cut flowers into our grey days to
awaken winter-dulled senses.
Visit any nursery this
month and you’ll likely be beset with shelves groaning beneath an enticing
array of hardy spring bulbs while each day’s mail presents yet another tempting
catalog filled with treasured heirlooms and promises of the newest
introductions. Such colorful assaults coupled with fond memories of our annual
vernal reprieve—that day we saw the first golden daffodil *sigh*—has caused
more than one of us to dream big and spend lavishly. We lay out our hard-earned
garden dollars and commit to spending many a rainy autumn hour burying
unremarkable brown bulbs, corms and tubers—the promising insurance of another
growing season on the other side of winter.
Yet
too often, those muddy sodden hours on our knees result in a colorful, albeit
fleeting, spring show only to be followed by gaping holes in our planting
schemes and the disappointing sense that our resources have been squandered.
Here are some cultural tips for savvy returns on your garden investments.
In
addition to a cold winter dormancy, dry summer conditions are crucial to bulb
longevity, especially tulips, as this replicates their native environment. This
is generally in conflict with the needs of most summer perennials and may
require rethinking where you site your bulb plantings. Areas without summer
water, while inhospitable to many plants, are perfect for establishing tulips,
hyacinths, alliums and other spring beauties. Other measures you can take to
ensure many happy returns are providing a well-drained soil; amend clay with
large doses of compost or consider raised beds. Fertilize bulbs at planting
time and with the emergence of growth in spring, and after blooming
always—ALWAYS—allow bulb foliage to mature all the way to yellow.
NOTE:
please don’t braid, twist or otherwise adorn fading bulb foliage in an effort
to disguise a less-than-attractive, yet inevitable phase of bulb culture. It is
during this phase, delicately referred to “ripening,” that the leaves are
taking in and storing the energy needed to produce next year’s flowers. There’s
no denying that this is not their finest hour, but braiding, binding and otherwise
fussing with them only lessens the leaf surface exposed to the sun and robs
them of valuable photosynthentic hours —plus, you’re not fooling anyone.
Creative (and acquisitive)
gardeners quickly learn to layer complimentary plants forming compositions that
morph throughout the season to support the bulb (bloom) time/space continuum.
New plants unfurl to divert attention and fill gaps left by fading performers
in a sort of floral sleight of hand—“don’t-mind-that-man-behind-the-curtain”
sort of thing. Our inclination is to place bulbs at the front of a deep border
for easy viewing. In practice, I have found that the back 1/3 of the border is
actually the best place for a spring bulb show, allowing groundcovers and
crowns of dormant perennials to take up the foreground and carpet the soil from
which the bulbs emerge to do their thing. Later these same plants fill in to
disguise and veil the holes left behind once the bulbs are finished. Here are
some of my tried and proven favorite marriages for combining garden perennials
and spring bulbs as well as further cultural tips to insure these unions are
lasting.
The tightly coiled noses of
hosta begin to emerge mid-spring to clothe the garden with medium to large,
paddle-shaped leaves. These bold and lasting perennials prefer partial to full
shade and are surprisingly drought tolerant once established, making them an
excellent choice for planting beneath deciduous trees whose canopy provides
shelter but thirsty roots often create competitive, dry growing conditions.
However, most trees don’t fully leaf out until mid- to late-spring providing
the perfect exposure for daffodils, tulips and most other early-blooming bulbs
that actually appreciate dry summer conditions. Hosta foliage is also tops for
disguising the ripening foliage of these same bulbs which can be such an
eyesore.
I’m particularly keen on
the blue-green, emerging cabbage-like foliage of Sedum spectabile ‘Autumn Joy’ in
combination with ‘Princess Irene’
tulips. The foliage of this sun-loving, drought tolerant perennial expands to
form a “ruff” around the blooms and supports their stems during inevitable
spring storms. Another duo that has proved enduring is the brilliant orange of
tall, ‘Ballerina’ tulips coming up through a stand of Euphorbia
griffithii ‘Fireglow’. Single early, single late and lily
flowered tulips are known for their years of garden performance and little
species tulips are truly perennial. I love tiny Tulipa batalinii ‘Bronze Charm’
and ‘Apricot Jewel’ (to just 6 inches)
coming up through groundcover sedums and creeping thyme.
A classic combination we
should all effect is that of daylilies and daffodils. Most gardens have at
least one daylily and who doesn’t love daffodils! The foliage of the two being
nearly identical, the fresh daylily foliage serves to camouflage fading
daffodil leaves. Before the daylily blooms, lightly “comb” the foliage clumps
with your fingers to remove the ripened bulb foliage. Both plants can remain in
place without dividing for some time and will only increase in impact with
passing years.
“Minor bulbs,” a ridiculous
name for snow crocus, reticulated iris, snowdrops, wind flowers and other small
early performers, are the easiest to integrate among perennials and established
shrubs. Planted in generous numbers these beauties bloom beginning in late
winter or earliest spring, multiplying over the years to create ever larger
drifts of color when most garden plants aren’t even considering a break in
their dormancy. Picture a bare lilac underplanted with dozens of crocus,
creating a pool of rich blue or purple foretelling the bloom-to-come by months
to satisfy the eye of a color-starved gardener. Weave these tiny bulbs among
dormant crowns of perennials, along pathways, in gravel, even between the
stepping stones of a pathway. As ripening bulb foliage goes, these tiny gems
are pretty innocuous as most have delicate grass-like foliage less likely to
foul an otherwise pristine spring planting.
Every year I look forward
to the glossy foliage, beautifully mottled in burgundy, of Trout Lilies (Erythronium ‘Pagoda’) when they appear among the ferny, blue
foliage and pearly white blooms of Dicentra formosa ‘Langtrees’. The 12- to 14-inch narrow stems of the erythronium
produce several pale yellow lily-like blooms with a brown ringed center. The
grassy stems and pendant bells checkered in cream and purple of the Snake’s
Head Fritillary (Fritillaria
meleagris) complete a pretty picture
pleasing from a distance, and mind-boggling up close where the cumulative
intricacies of pattern, texture and color in this triad can be appreciated.
With considerably less
subtlety, the giant Fritillaria
imperialis explodes on the scene in
April and May. Their 3- to 4-foot stems, topped by up to ten brilliant yellow,
orange or red bell-shaped blooms are capped by a top knot of leaves resembling
the crown of a pineapple! Showy, to say the least. I’ve placed them among
several clumps of miscanthus where they serve as a welcome distraction from the
spring crew cuts of these ornamental grasses which later fill in to effectively
plug the gap left by the summer dormant bulbs.
In early summer the
starburst blooms of ornamental onions (Allium)
begin to show their stuff. In an awkward development, allium foliage appears
and ripens off before the bloom stem emerges. Placing these bulbs where they
will come up through mounding perennials and small grasses not only hides the
fading foliage but provides a context and foil for the amazing firework-like
blooms that would otherwise appear somewhat bereft and naked.
Many spring blooming bulbs
are seen as garden bunco artists, here for a costly, one-time-only, flash in
the pan display before vanishing into the great compost heap in the sky. In a
tight economy, lasting value may be the wisest investment of all. With these
tips and strategies I hope you’ll find the welcome—some would say desperately
needed—appearance of spring blooming bulbs well within your garden budget.
