The Huntington Botanic Garden notes on their information on 'Vera Higgins' that it is more robust and paler than 'Alpenglow'. And yes, they are often listed as the same plant, apparently they are not.

Here is a picture of both Alpenglow and California Sunset. Those in the center, more bronze colored, are Alpenglow. The others are California Sunset. They are in full sun and planted in the ground.

I find the leaves and rosettes on Alpenglow to be smaller than the C Sunset. Notice the parent plant on the left. The color is a little different, too.

This is a tree stump filled with gritty mix - all grit and no soil. The California Sunset get shade part of the day in addition to full sun. It is still stressed and colorful. The rosettes are as large as the palm of my hand. And generally during rainy months, my plants turn more green and they color up after the rains stop.

I have also found that rosettes of the same plant can show different colors. Look at the cluster of Sedum adolphii.

In the end, your succulents all need the same type of care - well draining potting mix and pot, plenty of sunlight, occasional water.

Sometimes, difference between them is minute. Crenda showed and explained very well.

Regardless if grown outdoors - in containers or ground, or indoors, good drainage is, IMO #1. I grow just about all of my succulents in mix of grit, perlite and some turface - no soil at all. I have even few other plants in same mix. Mix like that is much more difficult to overwater. More soil there is, easier it is for it to stay wet for too long. Some ppl use mix of cactus&succulent soil with perlite in 50/50 ratio, and it seems to work well.

If you think of most succulents in habitat, they are not growing in nutrient-rich soils, rather lean and mostly inorganic. They get whatever minerals/nutrients they can from it. Growing at home should be similar - no manure, compost, fine soils.

Some ppl fertilize very regularly and faithfully. Most recommended is the fertilizer that has ratio of NPK 3:1:2 (in US, the FoliagePro 9-3-6 is easy to get). It is also recommended to use only 1/2 of dose on the label. I have not fertilized succulents at all for over 3 years, this year on few occasions - they seem to be just fine. Others do with every (?) watering, maybe even cutting to 1/4 of recommended dose - I won't speak for them, hopefully some will post.

Watering should be thorough and when needed - that could be difficult to know, but it is when potting mix is dry (I think someone said: when soil is completely dry, water just day before - or something similar, lol).

You could help yourself with a bamboo skewer or chopstick - insert deep into mix avoiding the roots. If it comes out cold/damp feeling or with small particles sticking to it, there is still plenty of moisture and do not water yet.

It I safe to say that many succulents should be able to stay outdoors until nighttime temps stay consistently around 50*F. There are many that will tolerate less, closer to 20*F mark. Indoors, they may not be receiving as much light as they like, but if it is dark you can help by using supplemental lights.

Can't tell for sure about marks, but they could be just a mechanical damage (like being 'squeezed' when handled, or something was leaning against the leafs). Plants look over all healthy. If my plants I would keep them in full sun, now it isn't as hot as it was in July-August...

I found another picture of C. Sunset (after a rain). I usually take pictures of them when red colored, but here's one that is not.

The green is more of a bluish green than your original plant. That may mean nothing, but perhaps we should look at Sedum adolphii. They tend to be a little more of a yellow green. But as we said, the treatment of the plant will be the same.

I have used all the different potting mixes that Rina mentioned. I have settled with the gritty mix without bark because my summers are so wet and humid that even a well draining pot cannot dry out between rains. No one gets fertilizer during the summer because I don't water anything.

Ask any other questions that you have, but I agree with Rina. Your plant looks pretty good to me.

Awesome comments from everyone!! Thank y'all so much! I am getting ready to put these babies in pots. I'm going to go and see what I can find at Lowes/tractor supply stores ect...for the ingredients to make my own gritty mix as you all suggest. I had been racking my brain for over a week trying to figure out what soil to buy and I've never seen so many different views on ingredients LOL!! I do have a fresh bad of perlite sitting at the house if I would've needed it. Everyone's succulents seem to look awesome with the gritty mix that looks like tiny rocks. I had always wondered if they actually needed soil...now I know. I love this site!
