Title: Thorns on non-native orange trees in Greenwell Springs, LA
Answered by: Barbara Medford
QUESTION:
Navel orange tree has thorns, why is this?ANSWER:
The orange (Citrus sinensis) is a hybrid, possibly of pomelo (Citrus maximus) and tangerine (Citrus reticulata); it originated in Southeast Asia. As such, it is out of our area of expertise at the Lady Bird Johnson Wildflower Center, where we concentrate solely on plants native not only to North America but to the area in which they are being grown. This Floridata website, Citrus Sinensis, has more information, and specifically says, "The twigs on many orange cultivars are thorny."More Non-Natives Questions
