Plant descriptions, Q-Z
Scarlet Gilia, Gilia aggregata:

Grows one to two feet high topped with bright red trumpet like flowers in late summer.  Usually biennial, the first year producing a basal leave cluster, flowering the next year.  Great for fall color.  Full sun or partial shade.  Grows in open sunny locations or open pine forests.
Serviceberry, Amelanchier alnifolia:

A common shrub in our area often growing to 10' tall and fairly broad.  Puts on a wonderful display of white flowers in spring followed with edible fruit in late summer.    
Shooting Star,  Dodecatheon sp. :

Wonderful little spring flowers that recurve like a cyclamen.  I only have a few this year and I'm not sure how large they will be.  Definitely next year I will have more.
Starry Soloman's Seal, Smilacina stellata:

Only a few.  A nice plant for the shade, grows up to 2' with alternating parallel veined leaved off an upright stem, terminating in a cluster of small white flowers.  
Strawberry,  Fragaria virginiana:

A good ground cover for restoration but in the garden they can really take over when given space and sun.  Small but wonderfully flavorful  fruit.  3-5" high. Can be used to stabilize a bank.
Twin Flower, Linnaea borealis:

A compact flowering ground cover for shady and moist situations.
Carpets of these can be found in local moist forests. White flowers with pink throats in June.  A bit slow growing but wonderful once established.
Woodland Star or Prairie Star,  Lithophragma species  

A  small plant in the wild but grows considerably larger in a flower bed when given space.  Interesting small white flowers on a stalk that can be up to 15 inches high.  Blooms in early spring with a fairly long blooming period.  Nice in a woodland setting when planted in a group.  Easy to grow.  

Violets:  We grow a number of violets, some that are not native to the northwest.  We enjoy growing them and will continue to expand our selection and are interested in trading seeds or plants for varieties we don't have.
Blue Violet,  Hook Violet  Viola adunca:

A nice little violet for the shady open woodland floor.  Grows well in a garden when it gets less competition than in the forest.  Found throughout our area.

I also have a variant of this violet that has white stripes (pictured) on its petals. One of a kind!
Yellow Violet or Stream Violet, Viola glabella:

A common violet from our area found in dense shade growing around steam banks and other moist places.  It needs shade and water but when given a bit more sun it grows into a nice sized plants with many more blooms.
Bog Violet or Kidney Leaved Violet, Viola nephrophyla:

I found these plants growing in full sun on a Canadian lake shore in very damp ground.  If kept damp they grow into a tight clump of foliage just covered (as you can see) with purple flowers.  One of my favorite plants for a sunny damp location.  
Birdsfoot Violet, Viola pedata:

Not a local violet but from the eastern states.  A beautiful violet just the same with large violet/purple flowers and interesting cut leaves.  One of the more showy violets.

Viola Riviniana,  Not avaiable

Sorry,  that's the only name I know this wonderful violet by.  A native of England that has followed my wife's family all over this country.  Very beautiful flowers on a compact plant. Will spread but never becomes bothersome.  Sun or partial shade.  Rare, I don't see these in the market place anywhere.

Transylvania Voilet, Viola jooi:  

This violet is from Romania as the name would suggest.  Beautiful large flowers in pale pink.  

Viola Sororia,

Haven't grown these long but they are a common violet in the industry, not native here.  Very beautiful flowers.  We also have a speckled variety.
