Hello Peter,

I’ve got a challenge for you with this Crown of Thorns plant. The plant is obviously not as healthy as it was when it was attached to the roots. I cut off the top because it had these weird growths on it. If I had to guess, I would call them galls. What do you think?

Elizabeth,

Uggh! It looks like a virus that is mutating the tissue. It should be disposed of right away. Sorry about that! The bottom parts of the plant may or may not be infected, so give it a chance, but if the stuff shows up then dispose.

Wow you are good! Thanks so much!

Here is a picture of some cactus I bought at the nursery. It’s labeled as “Penis Cactus” but it doesn’t look any of the pictures I found online!

Enjoy your day!

Lan,

My google search for “Penis Cactus” pulled up this page:

Trichocereus bridgesii forma mostruosa “inermis”
Clone A (The short joined type)
“The penis cactus”

And there you go!

Hi,
Bought plant year ago and you repotted. Plant is on balcony in Mission Bay SF. Watered 4-6 cups every 2 1/2 weeks; fertilized in Sept.

Lower leaves of plant gets soft and shrivels so I cut off. However, as plant grows, the lower leaves continue to get soft and shrivel; is this normal? Also, some of the leaves get these brown spots as you can see in the lower leaves in the photo. What is this? From water? In strong rain and wind over a number of days, I cover plant with a plastic bag; is this necessary?
Thank you for your help!
Mary

Mary,

Your Dudleya is looking great! All succulents lose bottom leaves, and Dudleyas are no exception. They do get the brown spots and if its on a bottom leaf that will be falling off soon then there’s nothing to worry about. On upper leaves the problem is that Dudleyas prefer not to have water sitting on them, so in the ground it is often best to plant them at an angle so the winter rains roll off. Not as possible in a pot, but generally a little water on top won’t hurt the plant more than the occasional spots. Or bring it under cover when we get those too-rare rains these days!

Here is another round of mystery cactus and succulents. My sister went to Ojai and went to a nursery there and brought back these wonderful plants for me.

Thanks so much Peter.

Lan

Lan,

The plants are…

Top row: Adromischus, probably a Crassula, and Ruschia

Bottom row: Sempervivum “Oddity”, crested Sempervivum and Austrocylindropuntia.

Nice!

We have this little plant sitting in my shop and my coworker and I have no idea what sort of succulent it might be! It has what looks like roots coming out from places on the stem (even from the little one) but they might not be roots?

Thank you!

It’s a fuzzy little Kalanchoe, probably Kalanchoe tomentosa that is not getting enough light – it wants more light! They can get aerial roots coming off the stems so that when they fall over they will root from right there.

Hello there! So happy to have found your blog! I was wondering if you could identify these beauties for me? I took these at the Huntington Library in San Marino, CA but there wasn’t a little card with its name.

crassula

echeveria

The big green one is an Echeveria right? I’m not sure what kind though.
The flowers on the second photo were coming out of a plant (silly me I didn’t snap one of the plant with the flowers) but I cannot remember what it was called, any guesses?

Thank you in advance,
Nichole

Nichole,

The green one with the Ladybug is an Echeveria, possibly E. pumila.

The flower spray looks like a Crassula.

Hello,

Cactus Jungle Crew I bought a Dragon-fruit Cactus from you. It was in the green house. I wanna share a photo, one of your crew said to send a photo to see it in a happier place.

OK, so maybe. Maybe not. What do I know about nail art anyway?
