@Calif_Sue - I'm relieved to know that there is no such thing as a 7 ft Iris. The idea is simply scary. But your salvia is beautiful.
Haven't read your blog yet. Been too busy sleeping in, doing laundry and taking a breather from my battle with the Triumvirate, aka Yahoo (the 'yeah, we were hacked 2 yrs ago but didn't bother telling anyone till now' co.), AT&T (the 'we let Yahoo do all that tech stuff for us' co.), and Apple (the 'we're just innocent bystanders but we did just update both of the systems for your desktop and your phone' co.).
I knew that there were different 'colors' of salvia greggii but didn't know they all are called 'Autumn Sage'. Thanks for enlightening me. I know I tried to grow one called 'Hot Lips' which was a hot pink with white. A failure. I don't think it liked neglect and abuse when it was still a baby. Maybe mine is 'Cherry'. I dunno.
Used to have a neighbor one block over who had several large white salvias that came with the house. (She worked for Match.com Europe.) She moved, the house was replaced by a semi-McMansion, and of course the white salvias are gone. Had I known beforehand then I might have tried to save some of those pretty white ones.
I have tried Agastache but w/o much success. It was incredibly fragrant which is what forced me to buy it when I was at a neighborhood nursery. It did come back for a 2nd year but not as strong, and then it was gone. It was maybe when we had one of our brutally hot summers or when we had a surprise snow storm in mid-November. Since I have so little sun, I've resisted trying another one. But ya never know. May try again.
