Mine gets afternoon sun, but I water it about once a month. It will most likely start turning greener because the sun isn't as strong now. So if you want yours to be more pink. Just less water and as much sun as you can give it. This plant as long as it's acclimated could totally handle our summer sun. It just looks better and better when stressed. I have a piece of plant from the same plant as above that is rooted. This piece gets way more water and it's mostly green. Campfire I know will turn really red with less water and more sun. They have tons at my Home Depot and they're in the front of the building away from the boggy succulents in the back Garden Center. So they don't get watered nearly as much. The plants that are exposed to all day sun are red, but the ones that are being protected from the sun's rays are green.

Glaucous, yes. A bit anyway... Is this what you are referring to:https://www.giromagi.com/prodotti/src/stapelia_hirsuta_26275.jpeg its probably why its called hirsuta Ive not seen fuzz(at least not that prominent on other stapelias). Best specimen ive seen IRL was this one plant near one of out green markets, on a balcony. Old, well developed. Think i saw it bloom once... But dont remeber seeing any on it.. http://www.llifle.com/Encyclopedia/SUCCULENTS/Family/Asclepiadaceae/19218/Stapelia_gigantea http://www.llifle.com/plant_album/17384/8399 Edit: it is also probable, knowing how succulents can react to certain conditions, that it might be the result of high humidity...

I read there are around 250 species of Zanthoxylum worldwide, but I can't get ahold of the complete list. I find it strange that for something with such a thorny, knobby, beat up looking trunk there is no corresponding photo of it on the internet. I considered the thorn knob tree also which is a legume I think. There's the possibility that this particular tree was subjected to cruel and unusual punishment, causing it's twisted, contorted appearance. Perhaps some groundskeeper at Balboa Park knows what it is?

One of the Brassica family of plants on the lines of a Cardamine. Knowing the geographical location (not just the zone) would narrow them down. But there are squillions of them. Mostly considered weeds if they're in your garden beds.
