what about larix .. the larch ....

train it as tall as you want ... it goes back down ... takes well to severe pruning ...

plus... deciduous ... so no winter needle problems ...

A weeping Blue Atlas Cedar would work too, but Larch is one of my favorite trees, a deciduous conifer. I have a weeping larch bonsai.

i couldnt get BACedar to grow in the ground in my z5 ..just south of ann arbor MI ... due east of chicago ... plus throw in the whole roof deal ... and i would bet against it ...

larch on the other hand.. cant beat them back with a stick .... winterwise ... but i dont know pot wise ...

Picea abies 'formanek' is a tough, slow-growing weeper.

I actually almost bought a larch tree but it was only rated to zone 4 or 5. That is not low Hardy enough for my liking. They look really cool so I will have to check out if I can find this variety. Thanks!

be nice if you told us the secret of your zone requirements ...

get over to foxhollow conifers on the north side of chicago ... crikey dude.. you should be able to find anything... i would make an appointment in advance if i were to visit ...

There is at least one weeping pinus strobus out there. There is a jack pine called uncle fogy. There are several weeping Norway spruce, but maybe they get too big.

hehe, no special zone requirement. I just shy away from things rated zone 5. I find they rarely if ever make it through the winter. I typically shoot for a zone 3-4 on the low end. Things don't live long-term in these conditions but I like to get a few years out of things if possible.

Have you considered doing something like this?

Picea pungens ‘Procumbens’ is another option Rated zone 2.

I found this beauty
