Expert Insight

Evan Dackow, a master arborist, explains, "They're quite cold-hardy, up to zone three or zone four. They're actually not an orange. They're related to the mulberries."

Characteristics

Appearance

Passersby describe the Osage orange in various ways:

  • "It looks like a brain."
  • "It resembles a sponge."
  • Some compare it to cauliflower.

Scent

The fruit’s smell is as unique as its appearance:

  • Described as sweet and citrusy
  • Some liken it to celery or fresh vegetables
  • One observer suggested, "They should make a candle out of it!"

Edibility

Despite its intriguing scent, the Osage orange isn't edible. Dackow explains, "The fruit plays very little role in anything. Probably rodents eat it, but it's not something we can eat. It's a bitter fruit to the best of my knowledge. Not poisonous, just very bitter."

The Osage Orange Tree

  • Average fruit weighs less than a pound
  • Trees grow between 35 and 65 feet tall
  • Native tree that attracts pollinators

Planting and Safety

Dackow advises against planting Osage orange trees near walkways due to falling fruit hazards: "It’s an attractive tree. There is somewhat of a trip hazard as those fruits do fall, but the same as anything else."

Some locals agree, with one resident joking, "I imagine it could clock you if you're walking."

While the Osage orange adds a quirky charm to the city, it's just another thing New Yorkers must watch out for while navigating the streets.
