Knobbly Mesembs


Cute South African succulents in the Mesemb Family, also known as the Iceplant Family, also known as the Living Stone Family. Indeed! To be clear the actual family name is Aizoaceae, Sub-Family Ruschioideae. And yet they’re called Mesembs because at some point in the past the family was called Mesembryanthemaceae. And some will dispute the current family name anyway, and insist these all belong under Ficoidaceae instead. Don’t get me started!

Aloinopsis schooneesii

Small dense clumps of speckled blue-green leaves sit on large tuberous roots, which can be esposed over time to form an unusual bonsai. Yellow flowers in spring.

Titanopsis calcarea

Small clumper forms dense mats of thick open leaves. Winter-growing, keep dry in summer. Grows in limestone strewn areas.

Ceropegia Flower Just Starting to Open 


Ceropegia serpentina is one of the strangest succulents with a basically bare stem that travels in weird directions. Until it blooms. Here it is just starting to open. And there are more than a dozen more buds still to come! 

Stapeliads for everyone!

Winter Succulent Damage


Hi cactus jungle

A few of my cacti have struggled after the rains.

I have attached a photo and I’m wondering if you can tell me what is happening with this plant.

Is it a lost cause😞? If not, how can I help it?

Thank you
Brian

Brian,

The plant is a Euphorbia, and hopefully it is just the tip that got damaged in the winter. Depending on where you live, they are only semi-hardy here in the Bay Area, so they can take damage to the tip when we get below freezing, or with heavy rains, or especially with both (See: This year.)

You can cut the top part off the plant and it looks like the damage is limited there. Cut at an angle, using a bread knife, and make sure the flesh is clean and white. If there is still some rot there, cut lower. Be careful when cutting a Euphorbia as it has a caustic milky-white sap. Where gloves, long sleeves, and eye-protection. Spray the cut end with Hydrogen Peroxide and put a paper bag over it to keep the sun off it until it is healed. Good Luck!

Haworthia Questions


Hi Peter
Would you be able to tell me the name of the succulent in the attached?

And perhaps more importantly, what is happening with the dry, papery bits toward the crown? Can this plant be saved? I am not sure what to do next. It was lovely and plump and then this started happening and I am not sure what I did (or am doing)

Much thanks to you!
Ann

Ann,

The plant is a Haworthia. It looks like it’s growing towards sun, maybe not enough sun where it is? It’s doing well since it can handle lower light levels for a succulent, but the result is the long stems with the dried leaves along it. You can pull them off or leave them in place, doesn’t really matter. But it is time to repot into a fresh fast-draining cactus soil and a larger pot.

Cactus ID Is Difficult 


Hello!

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!

Emma

Emma,

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.

We Get Florida Cactus Questions


Hello,

I live in Florida & would like to plant some cacti in my front courtyard.

Do you know some names of cacti that do not grow too big in size for me to plant in that area?

Kathleen

Kathleen,

Florida is a big state with many different climate zones. Also, if you are interested in true spiny cactus, most of them are not going to do well in most of Florida due to humidity. However if you are looking for more succulent plants then there are many that can do well – I would ask that you visit your local nursery and they will be best able to get you something that is climate appropriate where you are.

Thanks,
Peter

A Pitcher Plant Correction!


Subject: Re: April New Plants
From: Les
To: Cactus Jungle

Hi. Just an fyi: Sarracinia Bug Bat (?) is best known as Sarracinia Minor.

Sent from my iPhone

Les,
It’s been brought into our collection as a Hybrid. It may have also been a common name for S. minor, but we are referring to:

“Sarracenia ‘Bug Bat’ is a pitcher plant that was hybridized.. by Larry Mellichamp at University of North Carolina at Charlotte Botanical Gardens… Sarracenia ‘Bug Bat’ is most likely a cross of Sarracenia (alata × psittacina) × minor var. okefenokeensis….

“The name Bug Bat was coined about 2005 by David Crump alluding to the shape of the pitchers resemblance to baseball bats, and then associated with catching bugs.”

Thanks
Peter

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… (more…)

Urban Farming in Berkeley


Apparently we not only have our local Urban Adamah urban farm, on land, but we now have at least 2 new roof-top urban farms in Berkeley.

What?!?

From Berkeleyside,

Photo: The rooftop farm created by Top Leaf Farms at 2201 Dwight Way in Berkeley. Photo: Alix Wall

Whatever challenges a rooftop presents, though, are not apparent to a farming novice visiting the roof on Dwight. One can walk through numerous terraces and see neat rows of crops growing; it looks no different than a regular farm, except for the fact that you can also see the tops of nearby office buildings and past those, the Bay Bridge in the distance.
