Above: Graptoveria 'Fred Ives' in full sun and dry conditions goes tangerine. Below: in half-shade with regular water, 'Fred' is blue, green, and lavender.
We've gotten something this fall that didn't happen last year: a dozen or more relatively cold nights. Last night the low was a frigid 50F (10 C). Last year as I remember (not necessarily correctly), night time lows persisted in the low 60s nearly all winter and then through spring. I wore shorts and no jacket almost all winter! This fall, at least we're getting nightly relief from heat.
As a result of relative cold, touches of pink and orange have appeared in the Aloe foliage, aided unfortunately by dry, dry weather. We did get about 0.01" of rain over Thursday and Friday, but El Nino, we're waiting!
Aloe peglarae, already pink and curled in on itself to reduce sun exposure, has become pinker.
Ditto for Aloe microstigma.
A seedling's leaf tips reddened.
Ferox and marlothii were not pink at all this summer, so it was cold that did this:
Ooh! There's the flower stem emerging. Looks dry, though.
This young A. ferox has bronzed and reddened.
As did A. reitzii and an A. greatheadii offset.
Aloe vanbalenii made the most dramatic change from pure green.
A variegated A. noblis added some copper to its green and yellow stripes. The "taco fold" to the leaves is due to lack of water.
Part of the original variegated plant produced all-green offsets--which in turn produced variegated offsets of their own. Cold added bronze edging.
Aloe suprafoliata pinked up beautifully.
I need to move this when it finishes flowering. Maireana sedifolia will engulf it by next spring. A couple of years ago I regretfully cut the Maireana to the ground, thinking that would kill it, but it only seemed to rejuvenate it.
Snuggling up to a different Maireana sedifolia, Aloe pseudorubroviolacea finally has some rubroviola.
Aloe thraskii hasn't blushed up with color, but it does have three flower stems. This year's display may be quite impressive.
Other succulents also change color. Crassula pubescens ssp. radicans reds up in a bit of winter chill, though these poor bits are red from being too too too dry. Every once in a while I climb the slope to splash some water on them, but not often enough. Nice plant, wrong place.
With morning sun and water, it is much more green, chill or no chill. These were all dried up bits taken from the desperate clump-remnant above--regular water enabled them to grow roots and--grow happy.
A few deciduous tree leaves have colored--a Ginko down the road, the neighbor's Lagerstroemias...
...but the most reliable colors here are still the flowers of unthirsty plants. We got a postcard from the water company last Saturday; our district only saved 30% in October, so the water company said we must cut back to only one irrigation per week now, so that the water company is not fined by the state. Oh, please please rain more than 0.01" (1/3rd of a millimeter) spread over two days! It's so so so dry!
