I'm assuming you don't mean the white ones. The other looks like Eucomis, the pineapple plant, the me. I've grown it but never got down to sniff it.

Other people have mentioned the smell from this, but I have never noticed it on any of the ones I grow.

The common name is Pineapple Lily. This flower boils off a disulfide compound which gives an aroma akin to rotten eggs or meat in order to attract its main pollinator....flies. The aroma is at its most potent on newly opened flowers.

Certainly gets pollinated here, and self seeds all round the pots where it is grown. Fortunately they do not survive the winters

thanks for all the answers
