Been out of town on vacation for while, but was pleasantly surprised to return home to some bloomers...even in the 110+ degree heat.
Here are a few from the last day or so.
Arrojadoa penicillataI find it rather strange that flowers are nocturnal, but they only seem to open fully at night. Since then, I've found references in the literature that they are indeed nocturnal bloomers. Love learning something new - and surprising!

Fouquieria burragei - continuous blooms on this plant since April; easily my most prolific blooming
Fouquieria, even in this heat. Must be upwards of 10 inflorescences of varying ages right now and all are almost pure white, unlike in the spring when there was much more significant pink suffusion on the petals and rachi.
