Polyalthia Longifolia; rare in Hawaii, is a favorite tree native to India, used in public gardens and landscape as well as street trees. Related to the custard apples (Annonceae) its fastigiate growth makes it very desireable for narrow planting areas, close to buildings and as accents like Italian Cypress are used. It grows very well in the Hilo, Hawaii area too. One of the local area plant collectors and nursery owners brought in some seeds about fifteen years ago and introduced it. It became a very successful addition to local gardens and there is always the question .. " Where can I get some of that tree?" I have not seen it in high altitude gardens or over 1000 feet. It likes it warm and can with stand dry periods. Fruits are clustered, black. 0.75 inch. Hilo, Hawaii is noted for its abundant rain and the Asoka tree is not deterred. Polyalthia Longifolia (Asoka) should not be confused with the Sorrowless Tree (Asoka)
There is another Asoka tree (Saraca indica, Sorrowless Tree) (Caesalpiniodeae)related toTamarind, Brownea, Bauhinia & Ipil that also grows well in Hi. The flowers are wonderful to see and are brilliant orange here, 6" to 7" pom poms with lots of stamens so that the cluster resembles a large Mimosa or Lehua or Ohia tree blossom.
Both are definitely tropical trees as frost will kill them
