Biscayne Prickly Ash  Zanthoxylum coriaceum

Members of the Citrus (Rutaceae) family, their importance has suddenly increased, as a larval plant for swallowtail butterflies, in the face of the ban on growing citrus in Broward and Miami-Dade Counties, due to citrus canker.

Distribution of prickly ash used to be in coastal areas along the east coast of Florida from Palm Beach down into the Caribbean.  

It is quite rare to find one in the wild nowadays, since most of the natural coastal areas have been rehabilitated into more useful stuff.

Flowers create a sensation when they appear in the springtime.

There are both female flowers (left), and male flowers (below).

Pollinated female flowers develop into fruit clusters, which pop open, revealing a shiny black seed inside.  Crunchy!

A close-up of the trunk reveals where the "prickly" part of the name comes from.

 

Neighbors will ask you how your prickly ash is doing.  Show them, with pride. 

 

They generally keep a columnar growth habit, approximately 15' high, and about 7' wide.  They are much better behaved than their cousin, wild lime Zanthoxylum fagara.  Still, because of the thorns, you don't want to plant it too close to the house, or in areas of traffic.

Being coastal in nature, they prefer well-drained locations, in either sand or coral rock.

Plant in full to partial sun.  They don't need any watering once established.

At right are some beauties in 7-gal. 

Planted height of these is about 5' high.
