Marge,

A while back we discussed Cornus canadensis on Shadegardens.  I would not be 
concerned regarding failure with this plant.  Almost noone can grow it in 
garden conditions.  If one has to provide an environment that is so different 
than the garden which pleases, better to skip the plant.

This tiny dogwood grows naturally in the Adirondacks a bit north of me in 
good sized patches right on the roadsides. The soil is thin, it is very 
acidic and the plant almost always grows with some conifer shade.  The nights 
are cool although I don't know if that is a requirement.  The growing season 
is short probably around 100 days.

When we owned a camp in the Adirondacks, I tried transplanting some of this 
dogwood.  I tried at both ends of the season, spring and fall.  It is really 
unhappy away from home and never succeeded in the garden.  I also tried seeds 
without success.

Alchemilla alpina is not too difficult in upstate NY.  I have had one for a 
few years.  It does not increase much but is healthy otherwise.
