Just moved into a place in the Palos Verdes area of Southern California, and this large cactus is growing in the yard. I’d love to identify it and find out whether its fruit is edible.
It has:
- Tall, branching, tree-like growth
- Approximately 6 ribs on the younger stems
- Blue-green new growth
- A thick, woody base
I’m wondering if it might be Cereus repandus (Peruvian apple cactus), or something else.
Does anyone recognize it? I just wanna know if I can eat the fruit it produces. The previous owner said they never bothered to find out.

The scrawny, corky growth along the top of the soil represents ~20 years of abuse by my grandmother. It was mostly a "house plant". It spent years with basically no light whatsoever, almost no water, and even spent a few years without a pot lying on a shelf with what little potting soil clung to the roots. Never had anything better than a 4" terracotta filled with miracle grow.

When I got it 10 years ago it was just 8" of extremely etiolated cactus with 2 little pups. I decided to keep all that tortured growth as a memento to its hard life. When it got light, water , and nutrients the top grew a lot and it looked like a fuzzy lollipop until it eventually bent over and dangled out the pot.

I'm glad I didn't chop it off. I feel like the ugly corky parts hugging the pot give it a natural look you don't see a lot in cultivation

These must go and after several months away from facebook ive had to log in once again for marketplace sales hahahahahahha intend to delete again as soon as I can move these on but enjoy my selectoneglecto stock hahahahha

Gymnocalycium cv. ‘Flower Field’ by Uncle Chorn’s Cabin of Thailand

First flowers from my seed grown Arboricola x VRG Red Grandi. Started 10 seeds 4 years ago and this is the first flower from the 7 that survived up till today.

Got this guy 3 months back at a cactus show and in the last 2 weeks this has pooped up and I have no clue what’s going on …

Hola, buenas.
Mirando mis cactus que tengo varios, pero todos de la misma especie me puse a pensar lo bonito que son concretamente los saguaro, sé de antemano que es una especie protegida y de un clima muy diferente al mío, pues pertenezco a la parte oeste de España, donde el frío como mucho llega a 4° bajo cero y el calor llega a 40 o incluso 45. Aún así sigue siendo bastante más frío que donde vive esa especie. Por otro lado sé que es una especie protegida.m Mi pregunta es que para esta zona de España si hay alguno de ese estilo de los que tienen cuerpo muy ancho y le salen brazos.
La otra cuestión es que mirando bien el que yo tengo y buscando información no me aclara bien qué cactus tengo, ya que lo que siempre he pensado que eran retoños algunas páginas me dicen que son brazos.
Es un cactus con carisma, aunque me da tristeza que siempre tiene que estar con un tutor, pues ya sea por la extrema delgadez de su cuerpo o debilidad no se mantiene derecho.
Me gustaría saber la respuesta a ambas preguntas a cuál es mi especie de cactus y hay algo similar al cactus que crece en el desierto de sonora, pero más fácil de conseguir y que se adapte mejor a el clima de él oeste de España.
Gracias de antemano.

(hes a little bit to the right but i think its fine) also its perlite and cactus soil

Got this from a friend who needed it gone from her garden. This new pup has amazing red spines. Haven’t seen a flower so it’s making it hard to identify

In June 2025, I repotted my little Opuntia microdasys subsp. rufida. At least I think that's what this is, there's also an O. rufida, which is a different species, it's confusing!

I can’t remember when I sowed them but I collected the seeds in September of 2025

I’ve had this Turk’s Head (I think) for quite a while now sitting in a west window in Iowa. I water it once very dry, which doesn’t take too long usually. Every couple of weeks ish.

My question is why I can’t get growth in this guy. I swear it’s getting paler, and I’m not sure if I need to increase watering or give it different conditions. Any tips or suggestions?

I am so lost. I had a cactus blossom cacti, the pink top part died and then when I was about to throw it away it started growing a weird off shoot since August? Sorry I don’t know any of the terms about cacti, I just can’t find anything online about it. I just want an explanation please. Thank you🌵
