| I know there are so many varieties of this tree. I am looking for ones that are naturally not very tall ie maintain their low height w/o pruning.
Can you advise me in this regard? |

| You'll probably get asked to further define "not very taLL". Some other needed info may be how long do you anticipate owning this property as some JMs take forever to gain any size, so if short term you might want a tree that has vigor in it's growth. What are the surrounding features of the planting site? Do you want narrow or cascading or vase shaped? What about leaf shape and the different coloration patterns. Another forum you might pursue your questions is the Maple forum as there is considerable info available there on JMs. Good Luck. Marshall |

| Sorry for the lack of detail in my question. From Ken's link I do want it cascading with reddish leaves. There will be perennials/annuals in the immediate vicinity. Ideally I would like it to be less than 5 feet in height and hopefully closer to 4 feet. Would this only be attainable by pruning? (Thanks for that redirect to the "Maple" forum. I will post similarly) |
|
| One thing to consider is that "most" JMs will grow at a much slower rate than typically published. They suffer from winter dieback on a regular basis in zone 5...unless you have a micro climate. Acer shirasawanum and hybrids of the former with A. palmatum are the hardiest. |
|
| I am convinced that my zone 5b is really a 6. I see JM throughout the region so I don't think hardiness is a concern. |
|
| Just a suggestion but you should throw in your location under your user name. You have 5b, but to your point 5b in lets say Toronto, Canada is much different than 5b in a suburb of Milwaukee. |
|
| well, you dont want a high graft. |

|
| Duration of cold due to latitude combined with the heat island effect of placement in the middle of a large metro area versus a rural farm setting in the same zone makes a HUGE difference when zone pushing. |

| another way to say it .... is that it is all about micro climate in z5 ... i had little problem in z5 .. suburban detroit ... i can barely grow the dependable bloodgood in z5 adrian mi ... aka the country my theory.. the former horse pasture out here has no protection from blistering winter winds .... its more about desiccation of the trunk ... freezer burn.. rather than absolute cold.. of which zone basically is ... min winter temp ... the shishi survives.. basically to snow cover.. so mine is extra dwarf ... so if you can tuck it into a space where winter wind is minimized .... you might win in z5 ... joni mitchell discussed paving paradise.. my other theory is the suburbia.. with all its pavement creates a warmer clime.. where though the temp might drop to that magic number which makes your zone a 5 ... the retained heat.. in the heat sinks ... makes it less problematic.. that plus all the buildings reduce winter winds .. as compared to out here in farm country.. where they blow for miles without abating ... in other words.. i might hit min temp at 10pm.. for 12 hours... as compared to suburbia.. they might hit the min temp for only an hour or two.. on the same night ... duration of said temp can be the whole difference ... unproven theory at best .. as is a lot of gardening ... ken |
Here is a link that might be useful: link

| I know we are getting off topic but it seems to me that Canadian hardiness zones are arrived at using a greater variety of climatic factors than are the corresponding USA plant zones. And I quote from the Agriculture Canada website: scientists created a plant hardiness map using Canadian plant survival data and a wider range of climatic variables, including minimum winter temperatures, length of the frost-free period, summer rainfall, maximum temperatures, snow cover, January rainfall and maximum wind speed... In any event I am in a zone 5b (Canada) and specifically my home is part of a suburban community. I am quite confident many JM will survive just fine on my property. |

| No doubt they'll be fine if you see large specimens growing in your area. Out of curiosity where in Canada are you? Canada is HUGE! |
