FINDING UNIQUE PEPPER ON TERRACE GARDEN

Finding a unique chilli-pepper on the terrace garden.
Actually I have no idea what variety of this pepper.
I have thought that it's only a common chilli pepper.
But when the chilli emerging, it's really surprising.

The shape is so unique.
What a shame, the name tag have already disappear.

I think it's one of our ornamental pepper, but I don't know what its name.

Last year I bought a package of ornamental pepper seeds.
That was about 15 variety inside.
Hoping someone know what's the ID. 
I should ask about it to the seller...
And save any seeds for the next season.
