Purple Fountain Grass/Snail Vine Cold Damage
We went through a sub-30's freeze a few weeks ago (San Joaquin Valley, CA) and all my purple fountain grass and snail vines froze. I cut them back to ground level. Can I expect them to come back?

They may come back from the roots, especially the grass. I would recommend mulching the roots heavily as most of the country is expecting further freezes. This will give the roots a better chance of surviving these cold spells.
