Help identifying plant please

[Dragzena]

Please look at the photo. This has sprung up in my garden over winter and I have no idea what it is. Can anyone help please, thanks in advance :-)

Is it Melianthus major? Do the leaves smell of peanuts?

I shall sniff as soon as it stops raining, thank you :-)

Yes, it definitely smells like peanuts so you are spot on aircooled, thank you.
