A keen and experienced local (near where I garden) vegetable gardener (CEN) mentioned cabbages in a comment on a recent post. She mentioned a large cabbage with a pointed top, that was so large that it's chopped off in pieces for sale.

An early morning outside of Sapa found us poking around in nearby vegetable and flower gardens. There were the largest cabbages I'd ever seen growing in the understory of a forest canopy. This photo doesn't really reflect how LARGE the cabbages were, without a relative scale to compare.
As we continued to walk down the valley, a young woman overtook us, loaded with giant cabbages for market.
The other crop here was roses, destined for flower markets in Hanoi, and maybe elsewhere. They were grown with protective paper cones around the buds.
