Aroids for zone 7 garden
I'm not particularly interested in aroids for pot culture, but I love the unique leaves in my garden.
I'm always looking for more I can plant in the dirt and forget. Currently I have Amorphophallus konjac, Sauromatum venustum, Dracunculus vulgarus, and several of the Sinarisaema (Whorl leaf type) arisaemas, as well as the more common arisaemas, which have been doing nicely for years .
Are there other species or varieties which might survive in my zone 7 (some winters closer to 6) garden ?
I've tried alocasia and colocasia but very limited success with them.
