Arctostaphylos densiflora “Howard McMinn” is a really nice, deeply-red-barked, twisted-branched medium-height California-native manzanita that has a large showing of pink-tinged bell-shaped blooms this time of year.

They are not to be used as a border plant, as they are only to be used as a centerpiece for a small garden. OK, you can also use them as a feature plant in a larger garden. And they can occasionally be brought indoors in colder areas to be a houseplant sitting in a very bright window, but never in a green pot. Mustard and Burnt Umber are the preferred pot colors.

They can also be bonsai’ed, but that will take a lot of work to reestablish and maintain.

I don’t know anything about the Chicago Flower and Garden Show, except that it starts this weekend. Are there succulents? I don’t know! Are there orchids? Who can say! Are there proteas? Snapdragons? Chocolate bunnies? Only time will tell…

…and anyone else who gardens in San Francisco  too. CBS Channel 5 is reporting that organic compost being given away by the city is anything but. Don’t read this report while eating.

It’s called biosolids compost and its being given away by the San Francisco Public Utilities Commission for use in school and community gardens, and homes. But… that material is actually treated sewage sludge….

The problem is what often comes with it: toxins, from businesses, hospitals, heavy industry.

“Flame retardants, heavy metals, pharmaceuticals, steroids, hormones, PCB’s, all kinds of nasty stuff,” said Paige Tomaselli with the Center for Food Safety….

(T)he position of one of the Environmental Protection Agency’s own experts: “This material should be kept away from the public,” said Hugh Kaufman, a senior policy analyst at the EPA. “The EPA did a study a year ago of sewage sludge from all over the country and found large amounts of hazardous material in all of the sludges,” he said.

Anigozanthos viridis “Phar Lap” has the most sparkling aqua buds, that open into these deep rich green blooms. Tantalizing…

It’s good news in the Southern Tablelands of Australia – the amphibians are making a comeback.

OK, so if you read the article, they’re not making a comeback so much as hiding out and doing their best to avoid people.

Sometimes a day is a little brighter than the rainclouded overcast sky would allow; in the simple pleasures like this fat, long-leafed succulent.

Debra Lee Baldwin’s Agave potatorum is starting to bloom, as told on Gardening Gone Wild.

She wonders what to do with all the plantlets that will result. Any ideas of how she can share them, maybe while on her book tour?

We feature Lipson Robotics at the nursery, and the newest ones have rayguns! We don’t have any with rayguns.

I bet they’ll be up on etsy soon.

Yucca valida from my open back door. No way you’re getting me out there. Except to walk the dogs, of course.

It’s raining, again, and we’re a cactus blog, so to the google!

And up comes this interesting thing. Apparently it’s a type of musical instrument, and they’re available for purchase from the Lizard King.

Rainsticks: These beautiful & high quality natural rain sticks are made in South America from dried cactus. They have a natural tan color with yarn trim. We carry several sizes of these wonderfully soothing instruments at fair prices. The longer the rain stick, the longer the duration of sound.

From CNN we find out a common herbicide used in the US but banned in Europe may be the leading cause of falling amphibian populations.

Atrazine, a weed killer widely used in the Midwestern United States and other agricultural areas of the world, can chemically “castrate” male frogs…

Farmers in the United States continue to use atrazine on crops The herbicide has been a long-standing favorite among corn, sorghum and sugarcane farmers because t is affordable and can eliminate the need for tilling it is affordable and can eliminate the need for tilling the soil. Tens of millions of pounds of atrazine are used each year in the United States.

Anigozanthos “Bush Diamond”

These are the most subtle of the colors of Kangaroo Paws I have ever seen. And by subtle, I mean nobody ever buys them, and yet here I am putting them out again.

Will I never learn?!?

No! I will not ever learn! I like them and that’s enough for me.

Click on the image to see the much bigger version. Get right close in and see all those beautiful subtle hairs on those blooms.

I purchased these a little over a year ago from your Cactus Jungle. They seemed to be doing well, then suddenly developed this white substance at the end of the spines. At first it was just on the larger “barrel” cactus, but now it is on one of the smaller ones, too. Also, one of the smaller ones “shrunk” into the rocks. I see the white substance also on the flesh of the cactus. The spines come out easily and it seems to be shrinking. Do you have a diagnosis? What treatment, if any?

Thank you very much for your help. I really enjoy these cacti and want them to survive.

Nancy, it appears that your cactus have spine-mealy bugs. They can be treated with a paintbrush and rubbing alcohol and a treating with neem oil.

The cactus that shrunk into the soil appears to have passed on.

If you can bring them down to us we’d be able to treat them and figure out more definitively what’s going on.

We’re going big into birdfeeders and birdhouses this year. Here’s our new bird tree display.

We’re waiting for the rain to start. And for the tsunami to hit. Makes for an interesting day.

These are tiny little euphorbia blooms, and I didn’t see the aphids until I was working on the photos, and there they are! Click the photo to see the larger, more aphid-y version.

Euphorbia characias blooms and aphids.

Be assured, those aphids are already gone, long before this photo makes it onto the blog.

It’s a cactus salad recipe on What’s Cooking, a site that mixes recipes and photography. Here’s a photograph I’ve borrowed.

I see more of the coreopsis flowers have opened. I took the photo this morning before the storm started. And the storm has started.
