Cold effects

[Liz M]

Looking round the greenhouse and a few of the pots outside, I have seen how much the cold has affected plant colour. Some of the Sempervivums have gone a deep red, as have a couple of Sedums and a Delosperma. In the greenhouse many of the Echeverias have gone amazing shades of red but they appear in 'Winter Colour'. So here is Sempervivum calcareum

Then Sedum stenopetalum 'Douglassii', which is a very unassuming plant and very easy to grow but a lovely shade of reddish-brown

Then Sedum 'Red Raver', which will turn an even deeper red once it is in full growth, it has lovely bright yellow flowers, which make a good contrast with the leaves

Finally this Delosperma, which I have as D nubigens, as it has bright yellow flowers in late Spring. It has not been outside all winter, I brought it outside a couple of weeks ago, since when it turned red

i think they have turned red from bright light, this is the time of year you have to be careful of sunburn. when trees get leaves, there is more shade and the green color should return.

Bright sun and cool temperatures certainly bring out the shades. All my Delospermas are red, some quite startling. Or worrying depending on how I'm feeling that day

Hi Liz, I was considering this feature myself just this week. I have never seen the rupstre group of sedums quite so red.
The combination of cold, dry weather, with the increasing strength of the sun has combined beautifully. My Echeverias are now in growth as I have been watering for a month so the red is not quite as strong now.

Nice red Delosperma:

Does this count?

What plant is in the second one. It looks like a red blob.

Many of my Haworthia are as red as they get at the height of summer at the moment, apart from a light shower this morning we have had nothing but sunshine or hazy sunshine for the last 2 weeks with the greenhouse reaching the mid 80's.

Conophytum burgeri, I am certain.

"rupstre"

Could find only this so far...
And this. This doesn't count, does it?:)

i think you are correct. red from the cold not sunlight. every winter my myrtillocactus turn
red from the cold. only now are they turning back to green.
