Fall in the Pacific Northwest: A Kaleidoscope of Color

September 8, 2013

While I love summer in Seattle, I really do, I have a confession to make, fall has always been my favorite season – ever since I was a child.  Yes, I love the fuzzy sweaters and the opportunity to pull out my (too) many scarves from the closet, but it’s the colors of fall that truly make the season special.  There are times when I just can’t believe nature produces the colors it does.  If you’re interested in fall color, you’re living in the right place.  We have so many choices of plant material, from trees to groundcovers, it’s sometimes overwhelming.

Following is a list of some of our favorites.  Because there are so many great choices, I broke the list into trees, shrubs, grasses and vines, groundcovers and bulbs.  Can you tell I like fall plants?

Trees:

Full moon maple, Acer japonicum ‘Aconitifolium’

This graceful multi-trunked tree grows to approximately 8 -10 ft tall and wide.  It prefers to be in full sun to part shade.  It’s most notable characteristic is it’s palmate, almost fern-like, deeply dissected leaves.  The leaves are a medium shade of green through spring and summer and morph into numerous shades of orange and red in fall.  A true beauty that makes a lovely specimen tree.

Japanese stewartia, Stewartia pseudocamelia

Japanese stewartia is a columnar tree that can grow to 25 ft tall and 12 ft wide.  It prefers full sun to part shade conditions.  Lovely camelia-like flowers appear June through July, but it’s the gorgeous orange and yellow tones it takes on in fall that steal the show.

Katsura, Cercidiphyllum japonicum

Katuras can grow to be 60 ft tall and 50ft wide and prefer full sun to light or open shade.  It’s leaves emerge in spring with a reddish purple tint and mature to a blue-ish green through summer.  In fall they take on bright yellow tones with a hint of orange.  It’s a graceful tree who’s leaves resemble pearls hanging from a chain.  Another great specimen tree.

Korean dogwood, Cornus kousa

Depending on the cultivar, Korean dogwoods can grow to be 30ft tall and 25ft wide.  They prefer full sun to light or open shade conditions.  In June large flowers, actually bracts, emerge in shades varying from white, as in ‘Milky Way’ to the dark pink of ‘Miss Satomi’.  In late summer bright red fruit hangs from the tree.  In fall the leaves turn a deep red to scarlet shade – stopping passers-by in their tracks.

Grasses:

Variegated purple moor grass, Molinia caerulea ssp. ‘Variegata’

Variegated purple moor grass is a clumping grass that grows in 1 foot tufts.  In late summer flowers and seed heads grow 3 feet above the tufts and create a light airy feel.  It’s these seed heads that make for a beautiful fall effect.  They are especially gorgeous when the light catches them and produces a golden glow.  Plant this grass in full sun.

Feather reed grass, Calamagrotis x acutiflora ‘Karl Foerster’

Feather reed grass adds structure to a garden while maintaining some airiness and movement.  It grows in clumps that stand approximately 2 feet tall but it’s the flower stalks that emerge in June and grow to 6 ft tall that make this grass so unique.  These inflorescence mature to a golden color in late summer and persist through winter.  Again, consider planting this grass where the light can catch it, creating a golden glow.
