Ohhh I see Malaysia is a bit different from me When #4 was in flowering for me Sun time here at longest is about 15.75 hours buds where easy to see and nearly ready to open and did so with lesser sun light time and finished flowering 12 days later. Temps where in the 80 - 92 F range at the same sun times mentioned and the time of day mine opened was 16:00 hours to 23:00 hours For now I can say your heaviest rain season might be a bit much for #4 although the soil you have it in does look nice enough to drain fast enough. Again odd #4 Messeb like water more than most succulents but doesn't like wet roots for to long of time in days the top will rot out on you if to wet to long. Your other plants would certainly benefit with a lot less water than #4 can handle Other than a season rain over watering concern I have think you'll do very well with yours. As caution I think it would be best if you could provide a tarp or tent for some over head covering during your heavy tropical rain season over the entire garden bed. I and others here appreciate you and want to see your plants in there best of flowering later too. In all honesty it's best to tell you to talk to some of your local people with the same succulent garden passion as yours and ask them what they do.

A possibility for you on that 2nd one in the last bunch: Aeonium sedifolium (which was my first thought, but I nixed it, as your plant's leaves are not so plump as I would think it to have...but it does have the tannic stripes/coloring). Still, I would not say this is IT. :P Would like to see its blooms, if/when it does. =) Adding a link to a pic of one, but not sure GW allows this site when linking (we shall see). Okay, it would not, because of spam or other. This site also has other pix of this plant that look more like how I believe it should look. Also, I don't find this site has correct labeling of their plants, so don't fully trust them. So, google image this name. Maybe I'll email you the name of site!

It could be x Gasteraloe "Flow"

I think it needs a good soaking. It is trying to conserve moisture and is dropping old leaves. If you are unsure, stick a long toothpick or wooden kebab skewer deep into the soil and leave it overnight. Pull it out tomorrow, and if it doesn't feel dampish, you should water. It is possible your soil is compacted into a hard mass which water cannot soak into. When you water, watch if the water comes out the drainage holes immediately or if it actually soaks into the soil. If it pours out immediately, immerse the whole pot in a deep tray of water and let it soak for a few hours. Then use the wooden skewer to determine when it needs to be watered again. The purple colour is likely from the high light levels. happy growing! Breton
