Watched an episode of Gardening by the Yard that discussed the wonders of
Hyssop. Great for upping the butterfly and hummingbird activity. I like those activities A LOT!
This type,
Agastache rupestris, with it's tube-like flowers are great for the humming birds
and
Anise Hyssop - Agastache foeniculum is great for the butterflies. AND you can eat it and make tea with the leaves. Super good! I heart anise.
There are some "blue" varieties that are especially alluring to me and some with a bit of orange that Mr. VCA will enjoy.
Oh, and they said the deer don't like them. Win!
