I suppose that could have happened, I am familiar with root tropism in
pots. They were planted in 2015 when we had plenty of rain, we are in a
temperate rain forrest according to the Nat. Weather Serv. Last summer we
had an unpresedented drought, I have been here over 20 years and never seen
it so dry. We usually get up to 60 inches of rain and we were about  35
inches short, I think that we only got about 25" all season.

To many people in other places that seems like a lot but when you are used
to a lot of rain, the plants are used to it and have adapted to it. However
we can't grow good geraniums because of to much moisture an humidity and
other dry climate plants.

I am going to bareroot some of them and plant them in some very loose soil
and see what happens, our soil is predomantly clay here. I will make sure
they don't get dried out. If I do it now they will have to have some
protection as we can get frost any time in April.

Will see what happens, I would really like to have them in my garden.
