Hello, Franck,

Here in Canby, OR, USA, in a similar zone as yours, we successfully grow Dracunculus vulgaris and Arum italicum (in addition to the ones you mentioned) in the ground all year. They do just fine with a little winter mulch if it gets below 20F. Both of these are available from most of the larger mail-order nurseries. A Google search will give you more leads than you could ever look at in a normal lifetime. We also grow a number of hardy orchids outside: Bletilla, Pleione, Calanthe, Dactylorhiza, Roscoea, Spiranthes, etc. Some of these do well in full sun, and some appreciate a little light shade during the hot summer afternoons.

Franck, you could always try some of the more tropical genera like
Colocasia, Alocasia and Remusatia. All have a few species that can overwinter
underground in zone 7. Also a few of the Amorphophallus and I even know a few people
who over winter Philodendron bippenatifidum in zone 7. Those will dieback to
the ground every winter but given a well drained spot will come back with
full force in spring.
Where are you located?

I would love to see pictures. I'm also interested in how you grow the
"jewel" Alocasias.
