Thanks so much. It is horst Hofauer that I was thinking of.
How did you have that information on hand when you are so far away.
I thank you.
As well for the clear instructions on dividing Dahlias

I have had a great fondness for Brugmansia and usually look at that forum more so than Dahlias.

I live in Ontario Canada but winter in Ft. Myers FLorida. Imagine gardening year round.
It does present some problems though.
Things have to be put away for winter and manage on their own until I return in May.
Have lost some plants and tubers, etc. over this situation.
Have had to give up some things but I now have Orchids growing in my orange tree (with no care) Gingers flourishing, Brugmansia that survive on their own for six months lots of tropicals that take care of themselves when I am not there.
Again, some don't make it on their own. In the six years we have had a home in Florida, I have learned quite a bit of the differences of growing conditions.
Amazing the plants that grow in mostly just sand.

I bet I use Google ten times daily, maybe more. Such an amazing tool at one's fingertip.

Florida sounds grand for the winter months. Nice contrast to the cold north.
