Well, three nurserys today and no Physocarpus, B. vulgaris, nor even a vulgaris or bigger purple-leaved thingy mascarading as a Japanese barberry. I gave up and bought a Hydrangea paniculata 'grandiflora' --and this doesn't mean I won't move it later. I have come to the conclusion that those with really good gardens and landscaping are "garden proud" because it takes a heck of a lot of research, discrimination and time to find special plants and shrubs. I am going to have to purchase the B. vulgaris or the Physocarpus bare root. I really love purple-hued shrubs. BTW I had a drooping Leucothoe Fontanesiana "Nana" last summer which I kept on my porch and when I went to plant it, and keep in mind the folliage was spectacular, there were no roots! You seem to have an encyclopedic knowledge of shrubs so if you are aware how that came to occur, please let me know. Best to you and your family.

Your tree looks like a Colorado blue spruce to me. Blue spruces can range in needle color from bright blue to completely green. Only the cultivated types/varieties will have consistently blue needles. I would expect the new growth in spring on this guy to be blue-ish and harden off to greenish-blue like you described happening this winter. That is why half the tree looks green and the other half looks blue - the new growth is bluish while previous years' needles fade to completely green. You could buy a known blue-needled variety of Colorado blue spruce to plant near this guy or buy a green needled spruce like a Norway or oriental spruce. White spruce is another possibility, they tend to have greenish-blue needles too(not entirely blue or entirely green). Serbian spruce would also be nice as they have green needles with silvery undersides.

a pic would be nice .. you do understand the potential of all these giants you planted??? none of them are going to stop i the 25 foot range ... at best.. they will be that in 10 years ... the sky is the limit thereafter.. hmmm .. literally ... i worry you are going to be extremely over planted .. but i dont know the context ... so how about that pic ken

In order to give the overall yard some fullness, I think I'd create planting bed between the left of walk and side fence. Granted, there's not much room for trees, so you'd need to pick ones that fit. There's also only room for very few shrubs, a small amount of perennials. The rest would be groundcover. At the right side of the yard, we can't see it, so I couldn't say what could go there. It doesn't look like there's much room there either. As far as cost, it's like asking how much a person's clothes cost. The range would be vast .... possibly between $50 and $50,000, depending on who you are, where you're shopping and what event you're dressing for. Here, the yard is small. Something simpler than what I'm suggesting might cost less than $2K depending on myriad factors ... but if you wanted to start out with $5,000-dollar trees, scratch that number entirely out. Cost depends on lots of factors. I'll bet you have some vague idea on how much you're willing to spend ....?? If you shared that figure with a landscape designer who has knowledge of your area, they could likely tell you if you're being realistic or are far outside of the ball park.
