Native plant information and updates.

Arbutus menziesii

Arbutus menziesii, or the Madrone tree, is a beautiful tree native to Western Washington.  On a recent trip to Orcas Island I didn’t see any Orca whales but I kept spotting this amazing tree.   The most striking feature is the cinnamon red peeling bark in contrast to the young chartreuse green bark. The leaves are evergreen, alternate, oval and leathery.  The flowers are white, urn-shaped in large clusters, turning to orange-red berries enjoyed by birds.  This tree is not often found in the homeowners landscape, but it occurs naturally on dry, sunny rocky sites, especially around Puget Sound.  Arbutus means Strawberry Tree in Latin and menziesii is in honor of Archibald Menzies, a Scottish surgeon, botanist and naturalist.

I’m especially intrigued with the green bark.  It’s so vivid and bright.  I wonder about photosynthesis and what the advantage is to the tree to have such stunning bark.  Bright green to red to peeling away. And then ready to start all over again. I like this tree.

Clarkia pulchella

This is the first year I’ve grown Clarkia and I’m a believer now.  We grew it from seed for our plant sale at school and I was not impressed with its beginnings.  It was floppy and rangy and never could decide whether to grow up or down.  I transplanted four starts to a nursery pot and there was trouble.  Over the following month, three of the four starts withered and died.  They appeared to be suffering from too much or too little water, the leaves just collapsed and the entire plant died.  After talking with a few others who brought this plant home from the sale, I found that their Clarkia suffered similar fates.  We came to the conclusion that the young, tender roots do not like being disturbed, as watering was consistent.   They just don’t like transplanting. One person who took the Clarkia home has left it in the tiny little four-pack and she says it’s doing great!  So why does this little native resent having it’s roots disturbed?  Discovered by Lewis and Clarke, the journal entry by Lewis states that Clarkia pulchella was found in Idaho ‘on the steep sides of the fertile hills’.  That clue leads me to believe that it requires excellent drainage and perhaps rich potting soil absorbs too much moisture?  Hard to say for sure, as this is my first season growing Clarkia. The seeds are reported to germinate extremely well for gardeners.  I really like the flower show as it spills out of the pot and it’s been blooming for over a month.  Clarkia blooms in early summer and is an annual.  It reaches 6-18 inches in height (or length) and is a native to the Western US. I’m looking forward to growing it again next year!

Salal

 

Look at this beautiful plant.  Look at the green leathery leaves. Look at the soft fuzzy new growth.  Look at the fine bristly hairs, look at the petite urn-shaped flowers.  Look at those drooping little bells of white and pink. Look at this contrast of tender and tough.  Look at the smooth curve of the leaf and straight line of the stem.  Know this plant, one of the most common plants in the Pacific Northwest.  In the understory of our native forests.  Along roadways and sidewalks and very likely in your backyard if you live here.  Salal, or Gaultheria shallon, is a favorite of mine.  I noticed it today on Mother’s Day when my son gave me a lovely vase of flowers.  ‘Which one do you like best?’ he asked.  I immediately touched the Salal, in the center of the vase, and said ‘this one.’  Past the daisies and lilies I saw the Salal.  It’s used widely in the floral industry, but most people don’t even notice it.  It’s all over the West coast of Washington and some people don’t even know it’s name.  Perhaps they have never been properly introduced to this member of the Ericaceae, or heather,  family.  Well, it’s in full bloom now and bursting with energy as it sends out new shoots and leaves and flowers.  I saw this one last week at the Bloedel Reserve on Bainbridge Island, a magical place.  I like it best in the Spring when the new leaves are smooth, light green and perfect.  With age they become tough and can show signs of pests and disease.  In late summer the dark blue berries replace the flowers and are eaten by wildlife and humans.  Some day I want to make Salal jam.  Next time you take a walk through a NW forest, appreciate the Salal, often overlooked, but making our part of Washington evergreen.

Favorite quote from Plants of the Pacific Northwest by Pojar and Mackinnon “You can make a tiny drinking cup by shaping a salal leaf into a cone.”

 

Swainson’s Thrush

Swainson’s Thrush

It was summertime, deep into July.  I heard this haunting melody and was captivated.  I wondered if we had a visitor from another world.  With some help from a good friend I discovered it was the Swainson’s Thrush, a visitor in our woods for only a few months.  The call is heard in the early morning and late evening, just when the sun in making it’s entrance and exit to the day.  This bird is rarely seen, but the the song is not soon forgotten.  It has an upward, spiraling melody that is haunting and beautiful.  It’s a happy reflection on a cold and dark winter day.  To learn more, visit All About Birds, from Cornell as we wait for the days filled with light and the Swainson’s Thrush to return again.

 

Pearly Everlasting

Our cat is a true horticulturist. He loves plants. Whether it’s the smell or the texture, Pearly everlasting, or Anaphalis margaritacea, is completely irresistible to Sprite.  He rolled in it, sniffed it, rubbed it and was blissfully happy to be part of this lovely native plant.  Who knew that nature has created another catnip?  I see it blooming now in the ditches on the side of the road.  That’s a tough place to live so this must be a tough plant, and deer resistant too.  We should bring it into our gardens. I wonder if it would take over?  I’m sure Sprite would take care of that!  Donna at Gardens Eye View has done a wonderful post about this plant which you can read here.

Spring Ephemerals

Spring ephemerals.  I love this name.  It makes me think of wildflowers and dragonflies.  Tissue paper and birthdays.  Raindrops and  moonlight.  The name refers to those short-lived spring flowers that make a momentary yet glorious appearance in the early spring and go dormant in the summer.  Trillium is a well-known spring ephemeral, but there are many others that I was recently introduced to at the 2014 Northwest Flower and Garden Show.  I went to a talk by Susie Egan of Cottage Lake Gardens and her enthusiasm is contagious.  I only bought one plant at the show and it was the erythronium pictured below.  My first spring ephemeral!

Just the Facts:

Erythronium revolutum      Fawn Lily, Trout Lily, Dog Tooth Violet

The following list of spring ephemerals is from Susie Egan of Cottage Lake Gardens:

Shooting Stars
Dark Throat Shooting Star, Dedecatheon pulchellum, Western native from the North Cascades, most floriferous, magenta flower with large white spot and dark ring at base, the tube is yellow here joined and has purple-black near tip, loves moisture.

Vestal Wood Anemone, Anemone nemorosa ‘Vestal’, White with double white pompom in center, the ‘Belle of the Ball’, very popular and always sells out at my plant sales.

Bloodroot
Single Bloodroot, Sanguinaria canadensis, Called ‘bloodroot’ because its roots contain a red-orange sap used as a natural dye by native Americans, has fragile daisy-like flower with yellow center and distinctive deeply lobed leaves.
Double Bloodroot, Sanguinaria canadensis f. multiplex (syn. S. canadensis ‘Flore Pleno’, Exquisite double white flower with waterlily-like appearance, worth seeking out.
