Hi, I planted a blue salvia, salvia longispicata x farinacea, in October and it's done really well until very recently. The leaves are developing grayish spotted patches. The other plants in the pot (nemesia, bacopa) are all thriving. It's large pot Any idea what it could be? Thanks in advance for your help!

Could be powdery mildew. I'd pull the plants so it doesn't spread - or at least remove all the affected parts. https://growinginthegarden.com/how-to-prevent-and-treat-powdery-mildew/

Most nurseries that carry seeds have them, as well as big box stores, they are fairly common. Online you can get them from Renee's garden: https://sh2543.ositracker.com/159509/9151/url_16913 and other online seed shops.

I've learned about Coleus and Ornamental cabbage from "Garden Answer" on Youtube. They garden in Oregon, not AZ, but you should check them out if you haven't already. You two are my gardening favs!
