Gorgeous!
Rhinestone Cowboy, one I hadn't seen a pic of before, I think I can guess why you got that one Cowboy--Tok. Flavo.--also very nice, most of the tokudamas give me a hard time. Wondering what your soil/lighting conditions are like?

Shade,

You are right on the rhinestone Cowboy, but I also do like the Hosta.

My Tokudama Flavocircinalus was planted in '04 and this year was the first year I started to really notice it (and it still isn't that big), but it is starting to look good!

We have good, black soil. When I dig with a shovel I don't hit clay until about a foot down. There are quite a few trees in the yard so there is shade. I have a trickier time finding places for the Sun plants.

Here is a Bing Map of my house. I am the fifth house on the left North of 150th Street on Redwood Drive. You should be able to zoom in to see the trees in the yard (there is a row of White Pines at the back of my lot and there is a car in the driveway).

Cool map. Sounds like someone might have amended your soil at one time?
I have clay here in my backyard though my front yard had been amended at some point with some really dynamite soil, a pleasure to dig in.
I think the hostas photograph so much more beautifully with the shade from your trees. The color and variegation really shows off well.

Black topsoil is pretty typical here. It is never a problem digging and I am thankful for that. I just add some compost when a new garden is dug out. I am imagining the night crawlers are just going crazy under the wood chips.

For the photos, I try and take them when it is overcast and usually first thing in the morning (also, it is less windy then).

Another cool thing about the map is the leaves are on the trees if you select the printer on the bottom of the screen. A print screen shows up and they are using a Summer photo for the print photo.
