Hi, few basic questions please.
1. Do foxgloves give flower every year or every two years. Are they Hardy to be left outside in London?
2.are they suitable for growing in container? I heard they have a small root system so don't need big pot, am I correct?

Most foxgloves are biennial, sow and germinate one year, flower the next, then die after setting seed to start again.
The most common one, Digitalia purpurea, is a native plant hardy anywhere in the UK.
You can grow them in containers, if the container is very small the foxglove will be small
In the sticks near Peterborough
Just to add, they will need support by way of a cane if growing in a small pot or best kept in a sheltered spot, out of wind if not supported.
Thanks. I didn't know about them dying back and then relying on self seeding. It won't work in our gravel filled container border so I guess I better look at something else... Ta
