Arisaema-L Gallery Image Upload (2638) unknown- sold as thungergii

Now that you've said it Jim, the leaflets do look much more like subsp. u=rshima

than subsp. thunbergii. That's probably the answer, but we can only guess

without more to go by.

A look at the pseudostem might help since it's often quite distinct looking=or the

A. thunbergii can actually be one of three subspecies, ssp thunbergii, =ssp. urashima and ssp. autumnale.


The foliage in the photo looks more like ssp. urashima to me. Ssp. thunberg=ii has much narrower leaflets. I do not grow ssp. autumnale, which is qui=te rare.


I certainly agree that one needs to see more of the plant.! In my garden ss=p. urashima's pseudostem is green while that of ssp. thunbergii is reddish=2C and the inflorescenses are unmistakably different.
