I spoke too soon

After the freeze and frosts, my veggies all perked up and so did many other plants, but my 3 newly-planted princess flower shrubs (Tibouchina) and 3 Mexican bush sages (S. leucantha, pictured below) really suffered.

Compare backyard-planted ones with an unprotected southwestern exposure...

They were all planted from the same batch of plants at the same time. Just goes to show you... Microclimate really does matter!

I think all plants will survive, but it's a drag that some got nipped back.
