How to Grow and Care for Organ Pipe Cactus

As native grasses such as little bluestem (Schizachyrium scoparium and cvs., Zones 3–9) and prairie dropseed (Sporobolus heterolepis and cvs., Zones 3–9) increasingly gain traction in gardens, exotics such as miscanthus (Miscanthus sinensis and cvs., Zones 4–9) are losing favor because of their invasive tendencies. But not all exotic grasses are troublesome and need to be avoided. Feather reed grass (Calamagrostis × acutiflora and cvs., Zones 5–9) is a natural hybrid of C. arundinacea and C. epigejos, which are both nonnatives and prolific self-sowers, but the hybrid rarely sets fertile seed—a major plus for an exotic grass, right? So why are other reed grasses—‘Karl Foerster’ aside—so underused? To answer that question is to understand the phenomenon of ‘Karl Foerster’ feather reed grass (C. × acutiflora ‘Karl Foerster’).

Nothing says Christmas more than a poinsettia (Euphorbia pulcherrima). Did you know that December 12th is known as National Poinsettia Day? Plant breeders have developed a wide range of colors in hues of white, purple, orange, and pink, but red poinsettias continue to be the most traditional color of the holiday season.

Lee’s tips for growing pawpaw or American persimmon couldn’t make it sound more appealing, or simple:“Plant it, water it, and keep weeds and deer away for a couple of years, and then do nothing,” he says. No fancy pruning (like those apples crave), no particular pests–and a big, juicy harvest. More details on how to choose which variety to grow are included in the highlights from the April 29, 2013 edition of my public-radio show and podcast, transcribed below.

IF YOU ARE STILL USING any synthetic chemicals on your lawn, I hope you will stop. So does Paul Tukey. When he founded SafeLawns in 2006, Paul says, “It didn’t occur to people that their lawns could be dangerous.”“The sad reality is that we know that a lot of the chemicals used to grow the lawn (the fertilizers), or the chemicals used to control weeds or insects or fungal diseases—all  of these chemicals are designed to kill things, and they can make us very sick, and they make the water very sick, and the soil very sick, and the air very unhealthy.”Giving up chemicals doesn’t mean you have to pave over your front yard.“We will have lawns long after all these chemicals are banned in the United States, as they have been banned in Canada,” says Paul—explaining that more than 80 percent of Canadians cannot use weed and feed products, or glyphosate (the active ingredient in Roundup herbicide) because they are

“Last year [2012] at the overwintering sites, the area occupied was at only 60 percent of its previous low,” she says. “It had been declining, but that was astonishingly low.”The migration-monitoring program Journey North also reported lower stats in 2013’s cold spring. And though the numbers were only preliminary when we spoke that fall, University of Minnesota’s Monarch Larva Monitoring Program seems to indicate that “we’re at about 20 to 30 percent of our average,” Oberhauser says, acknowledging that these drastically lower numbers might be a “new normal.” But she’s not sounding defeated, by any means.A big positive: A lot of people are interested in monarchs. “Though it will be difficult to make up for all the habitat we’ve lost, we can make that ‘new normal’ as good as we can.”  (Ways to help are father down this page.)what going wrong for monarchs?MONARCH

Decades ago, I inherited the big old Clivia plant that had inhabited the sunroom of the home I grew up in for years before that. All these eons later we still live together, Clivia and I, as we have at several locations in between, though now there are multiple plants, each a division and each monstrously bigger than the one I started with.And then maybe 15 years ago I bought a yellow-flowered Clivia [above] at a botanical garden plant auction, and last year a young plant of a Clivia species unknown to me arrived in the mail as a gift from friends….so you get the idea. I like clivias. A lot.Alan Petravich, who a

The backstory: About 20 years ago my longtime friend and fellow garden writer Ken Druse and I were working on a book about native plants, called “The Natural Habitat Garden,” and I joined Ken as he traveled around the country photographing natives, in nature and in gardens.One of our wildest stops was up in Sebastopol, California, at California Carnivores, which has been open and dedicated to cultivating these dramatics plants–including various native American species–since 1989.  (A highly recommended destination if you are near San Francisco.) In 1998, Peter wrote “The Savage Garden,” but a lot has changed in carnivores in 15 years since the first edition–and even more so in the 40 years D’Am
