RE: eupatorium 'Gateway' now Euphorbia & potted plants

Thanks, Claire--I was just evaluating this plant, haven't bought one. We
have a heater in the pond all winter for the fish (it's not deep enough
otherwise). Sounds like this is not a plant for me.

Any experts on Euphorbia? I just got one called E. cotinifolia 'South
African Bronze.' Boy, the leaves are beautiful, sortof aspen-shaped,
papery-smooth, and a lovely reddish-brown. However, I can't find this plant
doing searches on Internet. The nursery guy said it's not hardy here and
should be grown in a pot. Anyone know anything about this plant?

That brings me to another question about growing things in pots: I would
like to team this plant with an Asarum splendens in the same pot. I'd like
the pot to have some extra space for growth.  How does one go about potting
large without rotting the plant? Or do these plants not mind? (The pot is
ceramic and I'll drill holes in the bottom.)

Also, can all plants be potted and then overwintered in the house? (Don't
have a coldframe.)

Thanks much!
Diann

Diann,

The Gateway plants I have are in the garden and if the season is dry (three
drought years here until last year's monsoon) they do poorly.  Last year in
the endless rain which was summer, the Eupatorium was terrific, best I have
ever seen.

The natural plants which abound in my area including a large patch at the
swampy edge of our pond (a large natural pond) will grow at the edges.  The
grow and flower when when the water is low.  The also grow right in the
water.  In our cold zone these plants do not grow as tall as reported
farther
south, five feet is about it.  I would not sink a pot of any plant in a
manmade pond and leave it overwinter here.  We freeze two feet or more deep,
sometimes three or four.  If growing it in my neck of the woods I would pull
that pot and put it in frame for the winter.

Diann, I would add that Eupatorium is stoloniferous and containing it in a
pot may be a problem.  It is a very large and vigorous plant.  I have white
form also, name forgotten this moment, and that is also a native plant.  In
nature Eupatorium forms large drifts and is always found in wet ditches.  It
grows better in sun than in part shade.

You will have to decide for yourself what is best for your plant.  I do hope
you got a good one and the flowers are what "Gateway' is supposed to
produce.
