*Update* Are Sichuan peppercorn plant(Zanthoxylum simulans(?) dioecious?

[thao]

It's producing berries now without any other plants in sight. Sorry I forgot to take a picture of the flower cluster when it was blooming, but take a look at the berries below. Though from last year, it also produce berries by itself, the majority were seedless and this plant seems to not be deciduous either. It has 3- 5 leaves, with 5 being the more common leaves on this plant, anybody know which type of Zanthoxylum it might be?

And sorry for the camera lighting, it was from a phone camera.

Everything I have seen about them say that they are dioecious.  Maybe she has one that, by some quirk, is monoecious -- it is not too uncommon for this to occur.  For example, black pepper is normally dioecious but nearly all commercial cultivars are monoecious.

If it is Zanthoxylum simulans, it is monoecious. Last year I have fruits on 2 years old plants. Similar species - Z. piperitum and some others are dioecious so you need both  sexes to get a fruits.

I actually don't know the exact species it is, but she has two different plants, one with 5 leaves and the other 7 leaves. I'll get a picture of them in the morning, since it's dark now.
