The Puna bonnieae ‘Inermis’ (accepted scientific name - Maihueniopsis bonnieae cv. Inermis) is a rare and fascinating species of cactus that captivates enthusiasts with its compact, globular growth habit and distinctive spination—or lack thereof. Unlike the standard Puna bonnieae, which features sharp spines, the ‘Inermis’ variety is notable for being nearly spineless, making it a more approachable choice for collectors and indoor growers. This unique adaptation enhances its ornamental appeal, making it an excellent choice for rock gardens, succulent arrangements, and specialized collections. 

Puna bonnieae is native to the high-altitude regions of Argentina, particularly in the Catamarca Province. It thrives in rocky, arid landscapes where it has adapted to survive extreme temperature fluctuations. Its habitat consists of well-draining, sandy soils and a dry climate, making it exceptionally drought-tolerant. 

This slow-growing Puna cactus forms small, round segments that cluster together, creating a low-growing mound over time.

It remains compact, rarely exceeding 6 inches tall, making it ideal for container cultivation and small garden spaces.

Each segment is about 2 inches wide, with a smooth, green surface that may develop slight texture with age.

Unlike many other cacti, Puna bonnieae ‘Inermis’ has tiny, nearly invisible spines, making it safe to handle.

The flowers of this Puna bonnieae ‘Inermis’ typically bloom in spring and early summer.

The petals of a flower are a light honey-yellow when it first opens, but they darken with age.

On the second day, before they fade, the petals turn into a rich tan-rose color. Yellow and pink flowers are occasionally found together. These blooms are short-lived but attract pollinators like bees, butterflies, hummingbirds, and other beneficial insects, making them a valuable addition to a pollinator-friendly garden. 

When it comes to care, the Puna bonnieae ‘Inermis’ thrives in full sun to bright indirect light. When growing indoors, a south-facing window or a grow light will help maintain its compact shape and healthy coloration. Keep it in temperatures between 60-80°F. It prefers low humidity, making it an excellent choice for dry indoor environments. Good air circulation is recommended to prevent fungal issues. 

When grown outdoors, it should be placed in a spot where it receives at least 6-8 hours of direct sunlight per day.

It is hardy in USDA zones 8-11, tolerating temperatures down to 20°F if kept dry.

In colder zones, it should be brought indoors or protected from frost with coverings or by placing it in a greenhouse.

Like most cacti, opens in a new tab, this species prefers deep but infrequent watering. Water only when the soil is completely dry, typically every 2-3 weeks in the growing season and once a month or less in winter. Use a well-drained specialized cactus  soil  mix, opens in a new tab

A low-nitrogen cactus fertilizer (such as 5-10-5) can be applied once a year during the active growing season.

The Puna bonnieae ‘Inermis’ can be propagated through offset division or seeds. Offsets can be gently removed and allowed to callous for a few days before being planted in dry soil. Seeds take longer to germinate and require warm temperatures and patience. Due to its slow-growing nature, propagation success rates can vary, but offsets generally establish quicker than seeds. 

According to ASPCA, the Puna bonnieae ‘Inermis’ is not known to be toxic to pets or humans, making it a safe choice for households with animals. However, while it lacks large spines, some species in the Puna genus have small, hair-like glochids, so handling with care is still recommended.

The Bottom Line

Overall, the Puna bonnieae ‘Inermis’ stands out due to its rare, nearly spineless nature, making it one of the more user-friendly Puna species. Its compact size, drought tolerance, and striking flowers make it an appealing choice for collectors and succulent enthusiasts. Whether grown indoors in a decorative pot or outdoors in a rock garden, this resilient cactus adds a unique touch to any succulent collection. Its low-maintenance requirements make it suitable for both beginners and experienced growers looking for a rare and charming addition to their plant collection.

Need lots of connectivity + charging. EXCELLENT.
Color: Gray
Problems with my original USB hub required something better. This unit has allowed me to connect all my peripherals to my laptop and I haven't had any problems with the USB port reliability I was dealing with. I'm using two hubs in series and now everything is working perfectly.

Yes, I wish I'd bought this on Black Friday, but still no regrets
Color: Gray
If you use a lot of add-ons like I do you won't regret buying this hub. The number of connection PLUS high power charging ports works for me. Printer, scanner, mouse dongle, phone, tablet, external drive, flash key all connect with zero problems to my Win 11 laptop. Saves my laptop ports from wear and provides a central location for charging my stuff. Solid metal construction, touch switches for each port, even slots forSDd and micro sd cards makes great design and features. Had a decent usb 3 hub but this one SO much better, good value

well made, nicely built, fast and everything fits firmly
Color: Gray
Sleek and well made, heavier than my old one, as it seems better built in every way. I love the flush power buttons, they don't get accidentally pushed in because of the firmness of the buttons, not hard, just not overly easy like some cheaper hubs. The color is nice looking, the lights are subtle but easily identify each port and the main thing, it's fast. My old USB hub was decidedly slow and often under-powered. It did not always work with some demanding devices. But as soon as I plugged this in, all my devices were recognized and worked correctly. This was a great buy.

Had some questions and needed to test it, here's the verdict!
Color: Black
No pictures, but I wished to get this review out as soon as possible because I'm very happy with my purchase. My last USB hub from aother brand broke immediately as soon as I got it which is why I wanted to purchase this as an "upgrade" for the higher voltage and more port options. Firstly I really appreciate that they gave both a USB 3.0 to USB-C and a USB-C to USB-C cable for the power depending on what type of port you have on your computer. The extra cable is always appreciated. I had a bunch of questions stemming from other reviews so I tested them. When you press a button nearby any port, the light goes on. When you hold it, it goes off. When the light is on, it powered my external drive, and when I hold-pressed it off, the drive on my computer disappeared as it should when no power is going to it. I'm glad that works perfectly. Also, it takes 16 seconds to recognize my 8TB drive. It seems a tiny bit long, but not too long, I'm pretty patient. For the SD and Micro SD card slot, there is no on and off power buttons. But they DO work. This was important for me as it was one of the reasons I bought it. The quick charging also works as intended. Also, I wondered what size it was- it's 8.75in long, 2in width, and a measly 0.65in heightwise. Every cord included is slightly larger than 3ft so there should be no problems with connecting it, though maybe it's too many wires for some. One thing I was concerned about was that a reviewer said the ports were very tight, and they are. I thought I was gonna break the ports by connecting a USB, but thankfully it didn't break. I don't know how realiable that is over time, though I imagine because of the buttons, the idea is to connect them once and if you want to not use it, to simply press the button to turn them off. So I think I'll do that once I get all my USBs set into place. If it breaks any port in that process down the line, I'll update my review. And based on the manual, here are the speeds: USB 3.0 & USB C - Max 5GB/sec data speed, Max 5V/1.5A power SD and Micro SD Slots - Read 50-104MB/sec, Write 30-80MB/sec (Subject to memory card speed and computer USB ports) USB QC Ports - No speed or power given Total power supply: Output DC 12V/7.5A (Input AC 100V~240V / 50Hz~60Hz / 2A) The power supply is a big brick LOL. But I appreciate the power, thanks. It's very easy to use overall, I just plug something in, turn the light on, expect it to work and it does. Besides it taking great force to plug a USB in, everything else is exactly what I wanted. Glad I bought this. Edit, a month or two later: The USB ports all still are working, but I noticed some external drives don't have enough power to work, even with the 8V, so I'm docking a point. I should be able to plug at least one in with a few other things connected, but this makes it a little less functional for my usage.

Just what I needed
Color: Black
Never given!give 5 stars. But, this got it because exceeded what I was expecting. Purchased because new computer slots were inconvenient and more new devices are using usb ports and having powered ports was essential. Have used for several months and keep finding more things needing it. It was more than I expected/needed at the time .But, was designed for growth I was not expecting. Getting excellent connections, speed, and reliability even though I’ve nearly doubled the devices I planned on using. To be clear the system I connected to is all about performance and top of the line hardware. I was a performance engineer in a previous position and am very picky with this system setup. I’ve tested the hardware several times tuning things and it’s never the bottleneck. The original purchase was intended as a short term fix when I needed something yesterday and as stated b4 it has earned a place in my permanent setup. Would buy again and would explore other offerings by manufacture.
