To go with your chocolate garden… Melianthus major (Peanut butter plant). It’s a weird, dramatic shrub with large, serrated leaves. And yes, it really smells like peanut butter. Zone 8.

My melianthus major has suffered from the frost – how do i/ can i rescue it ? It was thriving in a pot on our south facing decking and now looks rather sad.
There are obviously several plants that smell like peanut butter but the one I’m familiar with that the leaves smell just like peanut butter are Datura (jimsonweed). It’s very poison.
