Ficus Bonsai Ginseng outside in summer ??

I have a Ficus Bonsai Ginseng and want to know if it can be kept outside in summer. I have read several instructions on the care for this plant and they do not mention the option to place it outside in summer. I found an instruction however on the care for Ficus Retusa (which is same as Ficus Ginseng as far as I know), stating that the plant can stand temperatures to 50 "F (about 10 "C) and can be kept in the garden in summer.
My questions:
# Is Ficus Bonsai Ginseng really same as Ficus Retusa?
# Is it OK to put Ficus Bonsai Ginseng in the garden in summer?

Thanks in advance for Info

Ficus retusa is really Ficus microcarpa and a lot are sold here bonsaied. But I've never seen them referred to as "Ficus Bonsai Ginseng". F. microcarpa will grow out in the sun but if they've been in shade then you'll have to acclimatise them gradually to direct sunlight. Otherwise their leaves will scorch. I assume you're going to take them inside again when you get freezing weather. I doubt they'll tolerate frost.
