Saw these strange (to me) fruits—#Osageorange— today in Riverside Park #UWSNYC south of W 79th.

“The fruit of Osage-orange is where this and the hedge-apple name comes from. Osage-orange is neither a citrus tree nor an apple, but the large, round, green to yellow fruit suggest each to some extent…The closest relatives of Osage-orange are actually the mulberries. The mastodon used to eat them.
