*Artocarpus heterophyllus*, jackfruit, jakfruit, aca, nangka, is in the moraceae family, along with Breadfruit (Artocarpus altilis), Breadnut (A. altilis ‘Seminifera’), Champedak (A. integer), Lakoocha (A. lakoocha) and Marang (A. odoratissimus).https://pixabay.com/static/uploads/photo/2015/12/10/23/08/jackfruit-1087108_960_720.jpgPixabayDistant affinity includes Figs (Ficus spp.), Mulberries (Morus spp.) and African Breadfruit (Treculia african). I have to admit, jackfruit never crossed my mind when I planted figs and mulberries.
The tree originates in India, but spread throughout Asia and into South America early on. Today it’s found in Australia and the US as well.

Hardiness is only to about 27 F, but even that will kill off smaller branches. Young trees can’t handle sub-freezing temperatures, so should be covered on colder nights.
The tree can grow to be quite massive, sometimes compared to the majestic eastern oak
