As a child every time I ate a fruit with seeds I planted it in the ground or some dirt. I especially enjoyed the tropical varieties as well as the kind that do not grow well here in Seattle.
I guess I'm still that same little kid from many years ago. I planted some pomegranate seeds last yr and this is how they look today.
They CAN survive our Seattle winters so do not be afraid to put one in the ground.
I have about 6 of these plants around the yard.
