Both Cortaderia selloana and jubata are commonly referred to as "pampas grass" and both are freely naturalized in CA and considered invasive species. Neither is recommended for planting. And both have razor sharp blades and should be located well away from any foot traffic in those locations where the grass is NOT considered invasive.

There are plenty of Salvia growers but you might want to rethink using them for cutflowers. They're not the best for that purpose; they "shatter" quickly.

Robin, David does cite an exception to your list - the Deut will be happy almost anywhere in your yard and would enjoy the winter rains. Just as some additional information, one thing I've noticed is that there are several, if not hundreds, of exceptions, but in general most pachycauls go dormant. Under the above-mentioned structure, of all my Adeniums the Adenium arabicum never lost its leaves (so I watered it in winter) and, oddly enough, the from-the-winter-rainfall-area Pachypodium namaquanum lost its leaves for the briefest amount of time of all my Pachys (I had around 11), so if it was in leaf I kept watering it, although in San Diego they were protected from the rains most of the time in the winter. Up here, my Fockea edulis, Raphionacme flanaganii and Jacaratia corumbensis do not go out of leaf in winter, so they get some water, though not as much as in summer, when they're outside and in full (shaded) sun. The rest of the usual suspects (Cyphostemmas and Burseras, with the odd Commiphora) go dormant wherever I've had them. But I'd agree with you - learn what you have and where it's from, and that will help a lot.

Adrienne in Thousand Oaks: Regarding UC Verde Buffalo Grass, we installed it June 2021 so can attest to how it took watering twice a day to establish, then less frequently until we were watering twice a week with good results; I live in Thousand Oaks and were restricted to watering once a week for 15 minutes which was a good soak and it survived the limited watering last summer. When first planted as plugs we had a lot of weeds but it eventually filled in and is very thick. What we don't like is that is it dormant and brown in color from November to March; it has been slowly turning green in the last few weeks now that it is spring. It requires very little mowing, about once a month at most from spring to fall. The only way to buy it in Southern California is from FloraSource Ltd. They ship it as plugs in flats so it is labor intensive to have it installed; cost is twice that of sod.
