Salvia azurea (Blue Sage)

All three of the Salvia azurea I planted in the front bed did very well this year and even played host to an equally gorgeous moth, Pyrausta inornatalis.

The inornate pyrausta moth (Pyrausta inornatalis) uses members of the Salvia genus as host to raise its larvae.
A week or so after I saw the first adult Pyrausta inornatalis, I found a few caterpillars of the same species.
