Hello Paul! I do grow some of them. My area is at the beginning of Central Valley, just over the hill to our west is Bay Area. So we get the Central Valley thermal dry heat, but no snow here during winter, just the tule fog during the cooler months and some cold temps in the mid 20's to mid 30's range during some nights in winter.
I have some semps, but to be honest it is a struggle to grow them here due to the heat, even when shaded by the city trees. The blanket heat is intense, though this year has been extra nice with the longer Spring cool down. Most of my semps are noids too. Sometimes it is so frustrating when I buy semps from Bay Area, once I get to have them planted here, they would bolt quickly due to the heat, so I have learned to try and move them to as much shade, to help cool them down.
