Your Jasmine is a Lakeview Jasmine, Murraya paniculata. I have both the tree standard and bush form. Below is a link about their care. http://www.tropgard.com/plant_profiles/lakeview_jasmine.htm I keep mine outside with all-day sun in my driveway. I do water it daily and rinse down the leaves. There is new growth and continued flowering. These shrubs bloom several times a year. You would also need to feed your Jasmine weekly. What do you mean by the leaves looking sad? Burned, turning yellow, drooping? Do you have drainage holes in your pot, as standing water could be an issue? Did you regularly mist the plant since you received it or only start during this heatwave? Also, your Jasmine probably came from a perfect greenhouse environment and is trying to adjust to growing conditions in this area. I agree that is smells wonderful, second to my blooming mock orange shrubs. Trish :)

Thank you everyone for your care, concern, and for checking in. Luna seems to be feeing a little bit better today (at this moment). She's going in and out of having more/less energy. I'm still getting smiles, tailwags, and a little interest in playing with her favorite ball/duck at certain times but she doesn't have her usual vim and vigor. I asked her if she wanted a treat, and she stood right up and looked around for it, so that's good. (That wasn't the case two days ago.) Her coat hasn't changed and her gums look okay, so it doesn't seem like she's bleeding internally. She's beginning to act like she first did before when she was diagnosed with cancer, although nothing seems dire at this point. Of course we'll take her to a vet, when her condition requires it. Right now, I really believe they won't tell me anything I don't already know. The vet only gave her three months to live last May, so I feel like she's beaten the odds to be here almost a year later. At this moment, anything I can do to make her happy is hers. I'm glad she's here with us too. I wouldn't have it any other way!

It is dehydrated, but I'm guessing not because it's underwatered since OP says it's been watered recently. Can you help us learn a little more about the orchid: What zone or where are you located in the world? What is the light level? What is the humidity level? How do you water (frequency and quantity)? Do you fertilize and if so, how much and how often? What is the temperature range in your location? Do you grow indoors or outdoors or both?

It looks like sunburn is possibly caused by the sunlight reflecting off the inside of the container. I agree its nothing to worry about now. I'm not seeing a lot of roots along the soil surface. By itself it's not a direct indicator of anything. The soil mix looks relatively new or it was recently top dressed. Are there any drainage issues such as the container drains being blocked? Certainly not discounting it but it's Hard to imagine if this started a few weeks ago and you are in Houston that its a lack of water. I recommend you lay the plant down, check your drain holes, and slide it out of the container to see what is going on. You can then take the opportunity to back fill and raise the plant up in the container.
