Uses for non-fruiting pomegranate in forest garden

We have a non-fruiting pomegranate planted by previous owner of our property. I was a bit puzzled as to the tree's identity since I previously thought that all pomegranates produced fruit. I believe the variety is Punica granatum 'Flore Pleno' – multi-petaled ruffled orange or red flowers. It has pretty flowers and nice green foliage to look at which would probably provide a small amount of shade for some other plants. I'm trying to come up with some additional uses for the plant when used as part of a forest garden. Maybe this variety could be deliberately or just naturally crossed with some fruiting varieties to come up with some different and hopefully better varieties.  I'd prefer fruiting pomegranates and I got some seeds for those planted today. Does anyone know what the maximum ideal soil temperature is for germinating pomegranate? When looking at growing instructions for most anything, they usually seem to assume one is in a colder climate and/or that one is planting seeds as early as possible and give the minimum soil temperatures.

Almost all part of the pomegranate are useful. The leaves, bark, seeds, roots, peel, and even flowers can can be used.

It has been used to treat sore throats, coughs, urinary infections, digestive disorders, skin disorders, arthritis, and to expel tapeworms.

I have not used it so I can't recommend how to use it though I would suggest trying the leaves as tea.
