It is not unusual to have several weeks with night temps in the low to
upper
70's. Our humidity is not high as a general rule, so I'm talking basic
warm
night temps. Last summer we went for over a week with it sitting in the
low
to mid 80's. Plants that tolerate this seem to be of the tropical variety;
e.g.
Chinese hibiscus, bougainvilla and that sort of ilk. Irises sulk, mums
line
up on death row, daylilies self thin themselves (sometimes nearly to
extinction).
Some plants stress, but manage okay; e.g. platycodon, achillea. Siberians
get real marginal, enough so that I fully expect to lose any next year
bloom.
The JI I have (one now) didn't mind the heat as long as it didn't get to
dry.
The LA BLACK GAMECOCK is supposed to semi-dormant and the spuria
goes dormant, so who knows. Certainly neither seemed to have any effects
come this autumn. I guess I'll see how they bloom next year. Some of the
native plants I've moved into the flowerbeds were interesting as a
comparison.
Their survival rate was good, as you would expect, but their performance
was
sub par as compared to periods with cooler nights. They responded fast to
cool nights, but almost as quickly sulked when they returned to warm night
temps. I WANT COOL NIGHTS!
