I have this plant which I have grown as A.kirinense. What are the main differences between A.kirinense and A.volubile? I have grown this from seeds which I got from a friend who had gotten hers from another and originally the seeds came to Finland from Swedish STA, garden amateurs seed exchange many years ago.
My plant starts to flower about two weeks earlier than my A.volubile, but the flowering may overlap some. Flowering time is the main difference I see, and also A.kirinense is more compact (still tall), but I don't know how much shade/sun matters. The colour of the flowers is similar. Leaves are a bit smaller than A.volubile. Flowering starts here in the lat week of June, while A.volubile starts around mid July.
I have seeds from my A.kirinense, but before I give them to anyone, I would like to get opinions about if my plant is right or not.
