I would say azalea plants are pretty much local/native plants in Mobile, AL. Every house has to have azalea plants. It looks very similar to one of Thai flower, called “Cha-ba”. They are flowering as shrubs.
My house has the shocking pink color azalea flowers which start to bloom for the second time in this year (the first time they bloomed in early spring when I just moved in to the house). I have about four of them planted on the side of house.
Based on Wiki website, several commercial nurseries in Mobile, AL, are major national suppliers of azaleas in the U.S.
