Mexican indigo should definitely have blue flowers, and they would be in a long flower stalk.  This may be murraya https://en.wikipedia.org/wiki/Murraya  and http://hort.ifas.ufl.edu/database/documents/pdf/shrub_fact_sheets/murpana.pdf.  You might take a branch with flowers in to your local extension office for a closer inspection and identification.  Adrian Hunsberger would be the person to talk to: Adrian Hunsberger, M.S. Urban Horticulture Agent /Master Gardener Coordinator, <personal data hidden> Ext. 236.   18710 SW 288 St. , Homestead, FL 33030

Though it may look similar to jasmine it is not. it is a compacted shrub that is being used in our entry feature on NW 154 st and the Palmetto Pkwy. off the north bound off ramp. I am attaching a few photos. We are really stumped as to what it could be. I've ask locate grower and we get all types of different answers. (Mexican indigo, Mexican heather). I am the towns Arborist/ Horticulturalist and I am still having trouble Identifying it.

Do the flowers have any scent?  Are the leaves thick?  Are they borne alternately?  And flowers are borne singly?

I'm sorry, but you'll have to take a sample to your local Extension office or you could try a botanist at one of the botanic gardens in your area.  For example,
