I thought I read somewhere that you don't cut back those two, but I'm not sure. I have agastache purple haze just planted this spring and salvia may nights planted a couple years ago. Should I cut them back? Leave to protect over winter?

Thanks all,

I think that the agastaches and salvias that like it dry (like A. rupestris) prefer not getting cut back, but I don't know if it also applies to ones that like more average garden soil like yours.

In general I don't cut perennials back (unless there is a disease problem) since the crown is better protected in low-snow winters and they all disappear in average to high snow winters. I do almost all my cutting back in the spring.

All Agastaches should be left uncut over the winter, except for Agastache foeniculum and its cultivars. Yours is not A. foeniculum, so don't cut it back. Your salvia is one of the commonly grown salvias that can be cut back. Western salvias, which include cultivars like 'Ultra Violet', 'Black Cherry' etc, should be treated like the western Agastaches. Gaura also should not be cut back.

Thanks Lacey, I thought I read that the agastache shouldn't be cut back. Glad I didn't do it! :) I'll probably leave the salvia too until spring. Couldn't hurt I guess.
