It regularly gets to 100F (37.8C) under the shaded porch here, and the high was 106F (41.1C) in the full sun a few days ago. That heat wave ran through over the last week. Even though I moved the entire planter into the shade, I have lost a plant.
The count is now 2 live plants. On the bright side, our hot season is winding down, and as soon as it cools down in late September, I will take these out and resow. We have a nice second growing season from October until it starts getting cold at night in late December.
Sad days here, but looking ahead!
