Happy about these garden blues


I’m singing the blues with majestic sage (Salvia guaranitica)…


…with a blue bottle tree, purple skullcap (Scutellaria wrightii), and ‘Whale’s Tongue’ agave (Agave ovatifolia)…


…with Texas bluebonnets (Lupinus texensis)…


…and with more purple skullcap and bluebonnets, plus velvety mullein.


Another view of the purple skullcap and mullein, with winecups beginning to creep in


My new garden bed alongside the driveway even has a little blue in it thanks to Mexican beach pebbles that top the steel ring planter.


Well, it’s a work in progress. Currently I have three ‘Burgundy Ice’ dyckia and a ‘Blue Haze’ euphorbia planted in it, with a handful of beach pebbles on top.


Diana of Sharing Nature’s Garden passed along this beautiful, blue Agave franzosinii pup with me. I just gave it a fresh potting, with new aquarium pebbles as mulch for a neat finishing touch. I think I’m going to start refreshing my rock mulch on my xeric planters each spring. It makes such a difference to have all those leaves and pollen catkins removed, with clean gravel on top.


Leaving the happy blues…I’m actually feeling truly blue about this development: a plague of leaf-footed bugs on my softleaf yucca (Y. recurvifolia) bloom spike. All those creamy, white bell-shaped flowers are infested with nasty, copulating, plant-sucking bugs. I sprayed them with an organic pesticide spray (Captain Jack’s), but it didn’t do a thing. Any ideas? When I try to hand-pick them off, most of them fly away, only to return in a few minutes. Ugh.


Well, let’s avert our eyes and look at another white-flowering plant that’s perfectly lovely and unaffected by pests: star jasmine (Trachelospermum jasminoides).


Its sweet fragrance wafts up to the upper patio, making that a perfect spot to sit and enjoy the bluesy garden right now.

Garden Designers Roundtable: 5 Ways to Spice Up Your Garden with DANGER (just a little)


Is the scariest thing in your garden the risk of stepping in a pile of fresh dog doo? While real danger isn’t good—rotting deck boards, a spiny agave leaning out over the front walk, or a heavy piece of statuary that isn’t secured in place, especially if you have kids or pets—the thrill of a little perceived danger can be invigorating to a bland garden. Children instinctively know this, which is why they love climbing up into a tree house, leaping across a creek on slippery stepping stones, and picking up creepy-crawly bugs and toads to surprise Mom.

As garden makers, we can add small thrills in order to elicit a few more oohs and aahs from visitors exploring our gardens. Here are 5 ways to spice up your garden with a pinch of danger.


1. Plant a few “scary” plants, and place them where they can easily be admired without any real danger of injury. Examining and gently touching a thorny or dagger-like plant is thrilling; falling into one, not so much. Agave or cactus spines will draw the curious like Sleeping Beauty to Maleficent’s spinning wheel (“Touch it! Touch it, I say!”). Wingthorn rose (Rosa sericea ptericantha), bed of nails (Solanum quitoense), or Poncirus trifoliata ‘Flying Dragon’ are other good choices.


2. Make paths that require you to pay attention to footing or that feel a little claustrophobic. Your main walk should be securely constructed, so that even the most rickety grandpa or toddling child can traverse it to the front door without harm. But lesser paths can be a little more “dangerous.” Think stepping stones across a water feature; Japanese gardens are especially good at this. Or narrow a path around a large boulder or dense shrub so that you can’t quite see what’s coming around the bend. Add a surprising piece of art around the turn to heighten the thrill.


3. Add height to your garden and play with a feeling of vertigo. If you’re lucky enough to garden on a slope, this is easy to accomplish. Terrace your slope with patios or resting places, creating overlooks and the thrill of looking down from a steep height. Even a flat garden, however, can contain an exciting elevation change:


Add a raised platform—a deck, a yoga platform, or even a tree perch—to capture a view of the surrounding area or just a new perspective on your own garden.


Or try adding a large boulder or three as accents. You’ll see that kids love climbing on it, and you may want to too!


4. Let living creatures, even scary ones, inhabit your garden. We all want butterflies and birds in our gardens. But what about spiders, snakes, bees, and wasps? Can you have one without the other? Not really. Insecticides (including mosquito misting systems) kill beneficial bugs as well as harmful ones, and they may poison birds who eat contaminated insects. Go natural instead, allowing birds and beneficial insects to gobble up harmful ones. Remember that spiders are important predators of bad bugs, and bees and wasps are beneficial pollinators who generally won’t bother you if you don’t bother them. And most snakes that you’ll encounter in a garden are non-venomous and merely hunting pests like rodents. Be glad! For the most part, just let them be unless they’re really a danger.


I nearly walked face-first into a web occupied by a large spider in my garden one evening, and it scared the bejeezus out of me. But now that I know it’s there, I just walk around it, and I check the web each day to see what the spider has caught. She adds a little thrill of danger to my garden, and I like that she’s reducing the mosquito and fly population. Plus she makes a good Halloween decoration.


5. Be daring, try new things, live dangerously! Think about the gardens you’ve most enjoyed. Did the owners play it safe, content for their yard to look like everyone else’s up and down the street? Or did they surprise or wow you with unusual plant combinations, creative hardscaping, handmade garden decor, a playfulness, the zing of personality that you just can’t get unless you’re willing to risk looking silly or being thought tacky by the “safe” neighbor. Maybe your ideas will succeed, and maybe they won’t. But at least you’ll have tried, and that’s more than many people ever do in their gardens.

Boring gardens just slay me.

So the lesson here is, don’t play it too safe in your garden. Let a little danger in—perceived danger, that is. Be willing to make your visitor (and yourself) a little uncomfortable on occasion. After all, you don’t want anyone dying of boredom out there.

Now that would be really scary.

Hot potted plants for hot summer days


During the lazy days of summer, the last thing I feel like doing is standing for an hour with the hose in my hand while the Death Star beats down on me or mosquitoes suck me dry. So I skip right over all those magazine stories about making colorful potted arrangements of leafy tropicals or thirsty annuals and put water-thrifty succulents, cactus, and the occasional grassy groundcover in all my garden containers. As a bonus, they look good all year and don’t require switching out plants with the seasons. Here’s an old chip-and-dip set my mother gave me that’s now an easy-care succulent dish, accented with chunks of turquoise slag glass and glass beads. I’ve got a blue theme going here…


…but here’s a serendipitous color match with the salmon-colored rim of the container and the sunset colors of a small Agave leopoldii. Some succulents respond to the stress of drought or heat with a change of color. I assume that’s what this one is doing. It gets absolutely baked on the sunny deck during long summer days, and I often forget to water it.


I think it’s pretty this way.


Succulents like echeveria and sedum require a lot more shade in our climate. I grow them only in dappled shade or a little morning sun.


I’m growing an entire wall of them in my cinderblock planter wall. (Click for a how-to on constructing a cinderblock planter wall of your own.)


Another view. Cardinals have been nipping off the fleshy leaves of some of my succulents. I guess they find them tasty—like a juicy watermelon?


Echeveria in bloom


Its companions on the back steps are equally tough, although the purple oxalis does require watering at least twice a week.


These are tougher bad boys, requiring water in summer only once every week or two: Dyckia, a misshapen ball cactus, golden barrel cactus, and ‘Royal Spine’ agave.


You can go on vacation for a while and they’ll be fine. I like that.


Sadly, my fairly new ‘Royal Spine’ agave has some off-coloring that is not due to drought or heat. I suspect some type of sucking insect damage and need to treat it. Anyone ever seen this problem before?


‘Bloodspot’ mangave
Well, they’re mostly trouble-free.
