Taxus "Hicksii" could easily fill those dimensions you've described. It can get much bigger, you'd have to clip it back every year. Another option might be a trellis with vines, depending on how much sun it gets.

The rules in our subdivision require that a tank over a certain size (maybe 20 gallons) be buried. Our is over 300 gallons and it is buried. It was no big deal. Excavated the hole when digging the foundation. Poured a concrete pad and inserted bolts. Propane company dropped tank (with sacrificial anodes) into place and chained it down. Hole was backfilled with sand when the house was backfilled. The line runs underground (with safety tape over it so it doesn't get dug up) and there is a very small metal box where the line comes out of the ground and it connect to the back of the house. It's no big deal, a small shrub would completely hide it. The propane company owns the tank (so they say, I never signed anything) and they don't charge for it, but I am only supposed to use them for fills (it's only been filled once in two years). Our utilities are underground and our phone and power meters are on the side of the garage, not highly visible. The transformer is in the woods. The meters and boxes on the house are not bad looking at all. A small metal box for phone and cable, a meter mounted on another metal box with the shutoff for the electrical. They are barely noticeable, but we carely planned where they would go.

Thanks for the suggestions. I should have stated it's my pool propane tank that needs moving, they will not allow us to bury or paint it. I just called up a company that sells camouflaging rocks for tanks unfortunately not the kind of tank I have. I would have taken a picture today, but it's raining, will take when it stops. Right now I'm leaning toward putting a fence around it, with hanging plants. Guidelines also state they need "easy access" on one side. My husband is calling up other companies trying to get a better price, and we are hoping not to dig up more of the yard then we have to on the move. I've always said a house is the biggest sponge you can buy. Thanks again for all suggestions!

I am beginning to think really subtle camo - using the Dijon mustard tone for the top, and for the "face" that faces the road. No need to repaint everything! (Just about everyone on FB wants me to go Yellow Submarine -- and while that has a charm, it might just be a bit too cliched...) Adding little bits of creative interest in the camo parts at the bottom of either side of the tank is something I'm mentally toying with... AND, playing with the bushes, shrubbery and trellis will work there. For those who wonder, the yard does not yet have much in the way of whimsy -- right now the house is in the final stages of construction, so a lot of potential in several directions. I have several attractive rocks (New England!) the builders unearthed to set around while the equipment to move these is available. There is also an old abandoned rusty wagon wheel that I want to put somewhere. I can't move it myself, and it IS sitting in a patch of poison ivy. There will eventually be a chicken house and a chicken tractor. So, decor will also be "farm".
