New ones to me, but puntarella and sculpit (after looking them up) sound really nice to me. I enjoy arugula A LOT and it seems similar category.
I order all my Italian specialty seeds from this place:

I like to grow things which I can't find or are expensive when I do. Puntarella is one of those things I see occasionally but is rather pricy.
Last year I grew Cardoons which I have never seen sold until I went to the trouble of blanching mine (covering most the plants with burlap for a month) before harvesting and then... saw them being sold at Wegmans (an north east upscale supermarket chain)! That was oddly disappointing... Anyways, not growing them this year as I didn't care for the taste in relation to the trouble although they are interesting looking plants. I did try to overwinter them but they sadly didn't come back.
Edit: regarding puntarella I really wouldn't compare it to arugula as it has a different sort of bitterness and a different texture. It's great with an anchovy dressing and eaten this way you cut the stalks length wise soak them in ice water and run a knife along them after in the same manner that a person curls ribbon with the edge of a scissor.
