Salvia greggii x karwinskii cold/shade tolerance

We have a few Salvia greggii x karwinskii (Riverside?) thriving in a full sun southern exposure. I'm considering adding one in a spot facing northeast with exposure to sun most of the day in summer, less sun in the cooler months. I would not consider it a shady spot, but it does get less sun than the others.

How much shade/cold can this plant tolerate to bloom as well in full sun? Our winter temps can get dip to 26F, but most years about 30F. This spot will be low water, so over-watering should not be an issue

We grow these in full sun in coastal Northern California. I bet even in SoCal they can take almost full sun. As far as cold, ours have taken 25 degrees in stride. We list it as Zone 8 with mulching.

Thank you, Kermit. I know it can take full sun because ours thrive there now. I'm wondering if it would bloom as well in a spot with less afternoon sun.

At the Daniel Stowe Botanical Garden outside Charlotte, NC (USDA Zone 8a), it proved hardy in sun. The critical factor seems to be drainage, since the one planted on a high spot overwintered, whereas the one that was planted in a low spot that held too much moisture died.

Thank you, Richard. Ours get adequate moisture in full sun and seem very happy.
