Hi Irwin,

Thanks for the list of trees.  I fell in love with the Amur Chokecherry after
seeing a big one in Hideko Gowen's garden on a MN Hosta Soc tour the summer
of 1996?  So I promptly went out and got my own (maybe 1-1/4" dia trunk?) and
put it at the base of a hill in my new woodland garden.  It had gorgeous
bark, even at it's young age.  But alas, the following summer was a wet one
here, and it slowly drowned (according to best guesses). I even dug it up and
moved it to a drier part of the yard, but it was too late. The fall before
it's demise, I listened to Gary Johnson speak at our Washington County Hort
Soc meeting about his top 10 trees for Minnesota (based on their adaptibility
to many conditions).  Gary is, or was, an Assoc Professor at U of M, Urban
Forest, Arborist.  He considers this tree, as well as all Prunus a "crop"
plant (they last 10-15 years and then you have to replant).  It seems to have
root problems; girdling roots that grow to one side instead of radiating out,
so it's not stable.  But I sure loved that bark!!!

Anybody know other trees that would be better suited for gardens that would
have that almost metallic looking bark?  I know many crabapples have that
type of bark, but are they shallow rooted?

In case you want to know Gary's top 10 trees/shrubs for MN (at least during
that week (he has > 100 best trees and shrubs)), they are:
Oak, White 1st and Burr 2nd (Quercus sp.)
Japanese Tree Lilac (Syringa reticulata)
Concolor (White) Fir (Abies concolor)
Larch, European and American (Larix sp.)
Flowering Crabapples (Malus sp. David, Professor Sprenger, and M x zumi
calocarpa, plus he'll tolerate leaf problems on : Snow Drift, Red Splendor,
and Indian Summer)
Winterberry Holly (Ilex verticillata)
Hackberry (Celtis occidentalis)
Kentucky Coffeetree (Gynmnocladus dioica)
Ironwood (Ostrya virginiana)
European Black Alder (Alnus glutinosa)
He couldn't bring himself to stop with these 10 and so he listed a whole
bunch more too.

Now for the trees on his "Don't Plant" list are:
Ash
Boxelder - this and above break up easily in ice storms
Flowering Cherry - beautiful for 2-14 days (depending on storms) and lousy
root system and weak branches
Green Spire Little Leaf Linden - girdling roots - after about 10-20 years the
tree falls over (snaps off) in a storm, not safe
Crab apples - most bloom is nice but bad leaves or no leaves for most of
summer

Isn't it interesting that 2 different "experts" had opposite opinions on the
Amur Chokecherry??  I'd love to hear others thoughts on these trees.

p.s.  He also asked us "On the average, what is the most cold hardy part of
plants?" and  "What is the least cold hardy part?" (answers to follow)
