foxglove perennial

just been on the suttons websites buying seeds and they class foxglove as perennial but i always thought it was biennial (grows first year flowers the second then dies)i also got a pack of seeds that classified lupin as biennial (can't remember who from) but it's flowered first year. does that mean lupins perennial?? anyone know for sure

here's a link BTW

Sometimes if the plants meet ideal conditions they become perennials.

 

im in the scottish borders and intend to let it seed so between the weather and me letting it seed i assume it will die off ??? what would the ideal conditions be ?

 

There are perennial varieties of foxglove as well as biennial; a lot of the perennial ones are smaller flowered but equally as stunning and occasionally more unusual..

 

I can imagine not excessive cold for a start...
