Q.hebe plant indoors for winter
Can I bring my blue Hebe plant, 1.5′ tall, inside over the winter? Zone 6/7. 30 minutes NW of Philadelphia.

You can winter over your Hebe plant outdoors since it is hardy down to zone 4. If you bring indoors you will need a southern sun exposure and will likely need to add a grow light.
