They are just marginally hardy here in zone 9 so I don't think they would be happy out in your garden.Keep it in a pot so you can move it around easy-having it outdoors from late spring through summer,and then bring it indoors for the cooler months.Give it a dose of fertilizer around Easter.

My Jade stays outdoors in the sun all year. I only bring it in if we are expecting a hard freeze. It will be OK down to about 30 as long as the soil is DRY. It will not survive planted in the ground in your zone.

They can not handle a frost. I keep them outside from late April to early November here in zone 6B, so you might be able to add a few days in zone 7. I try to keep them drier when in the cooler weather.
