It is tricky to pronounce some of those plant names.

The rose name that was one of the worst tongue twisters for me was Rosa viridiflora.

Now that one I can kinda say if I roll the r's and kinda use an Italian accent, LOL!

California Poppies - no matter how you pronounce their name - has never done well for me here !

I grew them once here ( I think our climates are similar), and did the same thing as when sowing P. rhoeas, direct sowed early, I think March. They didn't reseed though, and I didn't try them again, but they were really pretty that year.

They like the Mediterranean climate we have here in California. It's dry during the summer months.

I got them in my garden by digging up a clump from a neighbor's yard and putting it in a container and setting the container where I wanted the poppies. I only watered it upon planting. It burst into bloom and set set seed and then died. I had poppies growing in that area the following year.

Now, when I dead head the seed pods before the second flush, I just throw them where I want poppies in another part of the yard. Often I only get a few plants the first year, but I get lots more the next year.

I have found they do better with some watering periodically, but not deep watering and not often. They have actually become rather invasive on the house pad level.

I figured that if I had to have weeds, I might as well have weeds that I liked.
