Tree Lupin

Have a couple of these growing in small pots in a corner of the garden. If I transplant them into pots of a fairly large diameter - would they be OK to stay in there - permanently? Or,do they need to be planted in the ground?

 

Probably best in the ground long term, but should be ok for a couple of seasons.

I dont actually think it is considered to be a long lived shrub at the best of times.

 

Thanks Pete - a bigger pot then for the time being. Unfortunately I have this habit of buying things that I see without considering where on earth I'm going to put them!
