Pawpaw flowers (Asimina triloba) at Fenner Nature Center in Lansing, MI. Pawpaws are the biggest edible native fruit in the US and are said to taste like banana and mango (I haven’t gotten the chance to try one!). They’re related to the custard apple/chirimoya(Annona cherimola) and soursop (Annona muricata); all are in the family Annonaceae.
