Your cactus is a Cereus c.v. Monstrose!


Summer Cactus Flower

It’s a cholla in full bloom! Well, it’s a single cholla flower. At least! Maybe I could zoom out and we’d see if there are more flowers.

And it’s a California native cactus too.

Medium height tree cholla, to 6ft tall. Flowers in summer.

Dave Sends a Photo…

…of a giant blooming cactus he got from Cactus Jungle!

Thought you would enjoy

A picture of a cactus we brought from you two years ago.

Nice. That’s one of our Echinopsis grandiflora hybrids.

Butterfly Mango 

Echinopsis x grandiflora “Butterfly Mango” 

Another giant #cactus flower! Sweet. It’s a good spring for cactus flowers. 

Cactus Hybrids 

Our newest hybrid grandiflora is Echinopsis “Rocket Pink”. 


Cactus ID Is Difficult 


I recently purchased a cactus to put on my windowsill to brighten up my room a bit, my problem is that I threw away the container right after I repotted it and now I don’t know what it is exactly. Could you help me?

The pot it’s in in this picture is four inches across and the ends of the spines are a dark red color.

Thank you so much!



Hard to know for sure at that size, but I would guess a Gymnocalycium, although my 2nd guess would be a Ferocactus. If it blooms young, it’s probably a Gymnocalycium. Also, it looks like it could use more sun.


Blooming Cactus 

Rebutia heliosa v melanistic

Origin: Bolivia

“Short Spined” variety

Clustering small stems, variable red to magenta flowers, spiraling ribs with prominent tubercles. Elongate areoles. Short, tiny brown spines. Purple-tinged stems in full sun.

Medusa Cactus

Ben brought in his gorgeous specimen Astrophytum caput-medusae, although he prefers to go by the name Digitostigma caput-medusae, which is considered a non-recognized name by the science boards that decide these things.

Ben says we may have some available to sell at the Cactus Jungle in a year or two. Nice! Thanks, Ben.

The horns are the cactus’ tubercles, i.e. what in most cactus are little bumps on or along the stems, here have gone wild and formed these giant spotted horns.

And the flower is cresting! Another closeup of the flower after the jump… Read More…


Our first epi flower  of the year has opened and its red! Cactus flowers for everyone!

San Pedro Cactus, California

We’ve had such stunning blossoms from this cactus we purchased from you 3 years ago. Thought you’d like to see our biggest crop yet! The photo was taken today.

Rock Cactus 

Ariocarpus fissuratus is a geophytic star-shaped cactus from Texas. This one is pretty old, and the most perfect flower I’ve ever seen on an Ariocarpus. Won’t generally bloom unless they’re 10 plus years old. I’d guess this one is closer to 20.

Eve’s Needles

Austrocylindropuntia subulata bloom at the Cactus Jungle. Everyone loves a cactus flower!

Origin: Peru, Argentina And Bolivia<

Description: Andean tree cholla gets 12 feet tall in habitat but can reach 25 feet in Bay Area, tubular leaves, long spines. Creates a very effective living fence. The fruit often drop and root in place.
