Shrubs for large pots

Yes, we relocated to there just recently Maw it’s even more bracing than Skegness!

Well, -20 may be pushing it , but we have lost plants that were supposed to be fine at -15 before now.

-20 lemongrove???
Outer Siberia?

We have three large cordylines.
One red and two green (with white strip)

Yes, we need to see something growing in them all year round.Acers do look great in pots but also have too much of a spread to them.

Does it have to be evergreen, because acers look wonderful in large pots.

Thanks Gramm have never grown Daphnes so will look into them.?

I love daphnes! There are many varieties, most are evergreen with wonderful scents. They flower in early Spring. They can be grown in containers. I don't know about hardy to minus 20 and hot sun!!
