– “To Do” List For Native Plants in April - May 2001
Watch carefully at least through the middle of May for
those early “wet weather” leaf diseases and treat if serious. Native are
pretty tough but watch Serviceberry,
Madrones,
Chokecherry, crabapple and
Bitter Cherry.
Drought Preparation. A lot of you are worried about
the possibility of a drought this year in the northwest. So far in March and
April, rainfall has been normal. The problem is the lack of normal rain and snow
in the winter and subsequent low water in storage both above and underground.
Northwest native plants have adjusted over the millenniums to the dry season
from late June through the middle of September. Trilliums and camas go dormant
– Licorice Ferns go dormant – native plants survive!! When native plants are
established, they survive without summer irrigation. However, I always recommend
some summer water for two years after planting out natives so the roots will go
deep, quickly. (Note that Christmas tree growers do not supply summer water,
even for newly planted seedlings!) The problem then becomes the possibility of
restricted irrigation water in the mid to late summer. Go ahead and plant your
natives this spring. But this year, use a maximum amount of mulch. I would like
to see 2 or 3 inches of bark dust or wood chips or whatever, around every plant.

– The Beautiful Fawn Lilies Of The Northwest
Erythronium oregonum, our beautiful
northwest Fawn Lily, is
in full bloom here in my gardens. The blooming period is very short. This lily is also
called Trout Lily, Glacier Lily and Adder’s tongue. It is about 10 – 12”
tall and has a tiny bulb. This lily likes some sunshine and humus soil. Petals
are white, with yellow tones. You can grow Fawn Lilies from seed but you have to
wait several years before they will bloom. The leaves have a unique mottled
pattern.
There is another fine Fawn Lily, the Pink Fawn Lily. I hope to grow this plant
next year. It is similar to the Fawn Lily above, but all pink.

– Creating A Wildlife Habitat
You can create a wonderful
native plant garden and, at the
same time, create a fine wildlife habitat, large or small. The lowland corridor
from the Canadian border, south throughout the Puget Sound country and Seattle
to Portland and the Willamette Valley to Roseburg, Oregon, are all similar areas
for plants, climate and wildlife. Wildlife includes mammals, birds, butterflies,
insects, etc. Large habitats should have a frame of large evergreen and
deciduous trees. For more modest projects, use shrubs, both deciduous and
evergreen, with some perennials. Wildlife need food, water and shelter. You must
solve the water need. The plants in the next sections show my choices for food
and shelter in the western Washington and western Oregon corridor. Try to include species
that form dense thickets such as hawthorne and native roses – protect the
little “wildlife.” Study how tall each plant you select may grow so you fill
in with food and shelter at different levels from the ground up. Always include
Snowberry for winter food. Try to include at least one evergreen for winter
color – don’t forget that Red Osier Dogwood will have very attractive bare
winter red stems.

– Calypso bulbosa – Beautiful Northwest Orchid
The Fairy Slipper is now in bloom! This is a
northern orchid that goes dormant in May
and grows again with the first fall rains. This is a very tiny orchid with a
single leaf. It grows in the shade in the top layer of moss and decayed needles
and leaves. It has an onion-like bulb. This little sweetheart is very hard to
grow. If you are an orchid expert who has had positive results
researching and developing techniques for propagating and growing this plant,
I'd love to know of your success. This plant is often decimated from its native
habitats by overzealous collectors. Any way we can help promote the safety of
our native orchids, the better.
On Taming The Fairy Slipper
From
around the world in Northern Climes,
Alaska,
Labrador, Norway – East and West
The
little Orchid of the cool, damp Forests
Daughter
of Aurora Borealis
When
cool days and long nights return in the Fall
You
send one leaf up from your summer sleep
And
bravely hold your place till Spring.
Then,
miracles and wonders! –
The
beautiful exotic Fairy Slipper displays again
Her
Royal Purple raiment, proof positive
Of
Royal Heritage and superior Social Order.
Unseen
tiny Woodland Fairies, dance attendance -
The
Giant Firs and Spruce bow to her sovereignty.
For
one month this beauty reigns
Then
sinks below the moss
As
warm days and short nights loom .
And
I, in my humble nursery, vow to tame this
Wild
Beauty and make her grow against her will.
In
neat nursery rows, pampered, prime and proper,
but
free no more!
And
if I do, how will I feel? - perhaps
To
free her once again before I sink below the moss.

- Personal Notes
From my window I see two huge
Big Leaf Maples in a corner
of my gardens. Over the past fortnight, every day the buds open more and more to
finally form the large beautiful new maple leaves of these magnificent trees. I
am amazed and humbled by this ancient ritual of mystery and beauty and renewal
and growth and creation. Do you know that every cell in a leaf is like a
miniaturized factory with thousands of intricately designed molecular machinery
containing millions of atoms, without parallel in the non-living world? I am
overwhelmed by the grandeur of a tree – of a plant – of a garden. Health and
renewal and humility and joy are found in a garden! You do not have to look far!

Good Luck!
