I drafted this post on a plane back to San Diego after having spent most of week in Philadelphia for a conference. This particular conference has the perverse habit of holding almost all of its meetings in February, almost always in places where winters are less benign than California’s.

Philadelphia sunrise. This was about 3:30 a.m. San Diego time.

Last week I walked on snow, slipped on ice, and encountered sidewalks heaped with piles of dark, bleak urban snow. But I also saw still waterways encrusted with transparent ice, architecturally leafless winter trees, and stands of sturdy grasses asserting themselves through snow-covered embankments.

I didn’t die. I returned with all of my fingers and toes intact. But as beautiful as things were I felt out of place. Visiting other people’s winter was like visiting other people’s houses. You don’t know the rules. What can you touch? Where should you sit? When do you open the windows and doors on warm days?

Over time you can learn the rules and begin to feel comfortable in the strange house, but a week isn’t enough. It all still seemed exotic when I left.

These are a few shots from my exotic adventure, most of them taken the day after the conference concluded, most of them on a trip out to the Barnes Collection in the Philadelphia suburb of Merion.

The Barnes is best known for its important post-impressionist and early modern artworks, all of which are “permanently”* displayed in a gallery in the exact locations where its founder Albert C. Barnes placed them during his lifetime. I don’t think I’ve ever seen so many Cezannes and Renoirs stacked up on gallery walls in one location. It was thrilling and uncomfortably tight at the same time.

Outside the Barnes, in the arboretum

In addition to being one of the more important collections of post-impressionist and early modern art, The Barnes is also a small garden estate that calls the grounds an arboretum. This is a landscape of big trees and larger lawns. If you’ve read some of my other posts bashing lawns you’d probably never think you’d read me something nice about them, but here’s one thing: A lawn covered with snow gives you a sense of space similar to a lawn with no snow in the spring. It’s a flatness, whether the flatness is white or green, and the flatness serves as a uniform foil for the plants placed in it. You can still read the space and get a sense of how it would be during other times of year. Additionally I’d guess that it’d be easier to focus on the seasonal cycles when some things stay the same.

One of the plants with a label: Franklinia alatamaha. It originated in Georgia, but the little trees are now considered extinct in the wild there.

The greenhouse was closed on Sunday, but you could peer inside and window-shop for a climate even warmer than California’s.

All you cold winter-dwellers will know these plants better than I do. The only IDs I have are from the plant labels placed generously around the grounds. But I was deterred by the blanketing snow to go exploring off the cleared paths. It’s back to that other people’s house thing. Was it okay to go traipsing all over the place, maybe stomping on some precious low plants I didn’t see under my boots? There wasn’t anyone to ask on my way out, so I tried to be the good houseguest and wandered off only a couple times–nothing equivalent to peeking in closets or checking for dust on the frames of the host’s Picassos.

The new home of the Barnes Collection under construction in downton Philadelphia

A note about my asterisked “permanently” above: Many of the paintings were removed for conservation in preparation for the entire collection about to be moved whole to a new building on Philadelphia’s museum row, a prime block of land with plenty of room for a small museum, but not enough for even a small arboretum. The major soap opera and powerplay behind the relocation are the subject of the recent documentary The Art of the Steal. Plants don’t have the same dramatic value as wars over eight-figure artworks, so not surprisingly there’s no discussion of the arboretum in the documentary. Also not surprisingly I didn’t see any copies of the film available for purchase in the official Barnes Foundation giftshop.

Along with lots of other gardeners I’ve gone all sad and nostalgic on how gardens seldom outlive the gardeners. The drama of this collection’s relocation tells you that a will with very specific instructions is no guarantee that things will be left as you envisioned. Art collections, lifetime gardens—nothing is forever is it?

Red and green seem to be the predominant colors these days. Instead, how about a shot of hot magenta-pink against green? Of all my pitcher plants this season Sarracenia Daina’s Delight is probably looking the best of any of them.

Vivid colors aren’t the rule this late in the season, with brown being the increasingly prevalent shade. With fewer things like color to distract you it’s a good time of year to concentrate on the amazing shapes these pitchers assume. In their brown state it’s easier to see the little hairs on the leaves that direct the insects down into digestive juices.

For you color addicts there’s still a bit of color left. This species is Sarracenia rubra var. wherryi (a.k.a. S. alabamensis var. wherryi.)

And for you color addicts who like a more traditional red and green combo, could you do any better than this? It’s a cross nicknamed ‘W.C.’ by Jerry Addington after Karen Oudean’s Willow Creek Nursery, in honor of Karen bestowing on him this clone of the hybrid of S. (psittacina x rubra) x leucophylla.

Hmmm…how about a cross between Daina’s Delight and W.C. for gorgeous late season color and awesome patterning? If they both bloom next spring I just might have to make that cross and find out…

Unfortunately this is what the preceding plant looks like when you back away from the few remaining colored leaves. Most of the autumn color is from the pile o’ bricks in the background.

I’ve mentioned my fondness for the look of poison oak before. This is a relative from California and much of the rest of the country, Rhus aromatica, a.k.a. R. trilobata, the Gro-Low clone. It’s not poisonous, but not so amazingly colored as its evil cousin either.

Yellowing apricot leaves…

Euphorbia tirucalli, the Sticks on Fire clone, showing the orange and red colors that start to develop as the temperature plummets into the high 30s. I’ve grown–and battled to remove–the typical green version which gets pretty huge and out of control. This clone doesn’t get nearly so huge, but I don’t trust that fact enough to let it out of a pot.

This photo of a little plum is more interesting than pretty. These are the December leaves of one of those multi-variety grafted trees. Each of the varieties is coloring up in its own way.

Another Euphorbia, E. cotinifolia. This one’s a bit of a cheat. The leaves are this color all year until they drop for the winter.

A close look at the chalk dudleya, D. pulverulenta. Some of the white stuff covering the leaves has been rubbed off in the foreground leaves.

On the left, the mediterranean Phlomis monocephala, in its stressed gold-green summer coloration. Soon the plant will turn greener with more rains. To the right, Central-California Coast native Astragalus nuttallii with leaves edging towards blue and gray.

And all over the garden are seedlings showing lots of that green color I talked about. Here’s a young plant of the local stinging lupine, Lupinus hirsutissimus. It doesn’t really sting, but the little haris can definitely poke you. Handling a dried plant after it’s died down in the spring without gloves is not one of the more pleasant things I’ve done.

Happy fall, everyone. I hope you all enjoy whatever colors the season brings you.

But spring is here, and part of the far back yard has been blooming away. Its main colors are–you guessed it–blue and orange, mainly hot orange California poppies and sky blue flowers of nemophilia, baby blue eyes.

As much as I generally don’t love these colors together, it’s hard for me not to like this little zone of perky chaos.

Even the blue flowers against the brick hardscape reinforces the blue and orange (or blue and orange-red) colors.

But in a garden you hardly every have two strong flower colors alone. The varieties of leaf green serve as peacemakers, separating the warring colors and injecting their own shades into the garden color palette. Other secondary leaf or flower colors help the enrich the palette and keep the peace.

From some angles a softer blue-gray provides a background to the hot orange flowers. Here the foliage is the now-common chalk fingers, Senecio mandraliscae. It’s still a blue and orange theme, but the blue is less emphatic and the orange is permitted to dominate.

Little pockets of cool-colored plants provide areas of visual rest. Here’s baby blue eyes and chalk fingers with a dark purple-black aeonium. Pretend I cut back the dying narcissus foliage…

Some viewpoints let the cool colors predominate, with just a few punctuation marks of poppy orange. New into this photo are whitish-violet flowered black sage (Salvia mellifera), magenta freeway daisy (Osteospermum), with a softer orange-red desert mallow (Sphaeralcea ambigua) in the upper left corner.

I’ll have to rethink what the combination of blue and orange means to me, at least in the garden. These flowers may be gone in a couple of months. Maybe this a combination that I should embrace and associate with “spring.”

Spring is bringing lots of other colors combinations and other flowers to gardens around the world. Check them out at May Dreams Gardens, where Carol is hosting yet another Garden Boggers Bloom Day. Thank you, Carol!

I first photographed these two trees over a decade ago, when I was working on a little photo project on local sycamores. I liked the way the two branches seemed to form a continuous arc when viewed from the right angle. Today, one of the trees is ailing and has lost some branches. Still, this little branch detail remains. The vegetation around the trees has changed over the years, as you might expect, and now you’ll have to stand in the middle of a big coyote bush brush to view the effect. At least it wasn’t a cactus.

When I started my photo series a lot of things attracted me to the Western sycamore, Platanus racemosa: their interesting branch structure, their over-scaled and dramatic leaves, their amazing exfoliating bark. And of the handful of native tree species within a few miles of my house, the sycamore may be the most spectacular this time of year. On my last trip to to San Diego’s Mission Trails Regional Park, I paid closest attention to what these trees were doing at the beginning of winter.

These are deciduous trees, along with the cottonwoods and willows, and they’ll attempt autumn or early winter color. Often the leaves are as much brown as they are yellow.

With a backdrop of gray sagebrush and black sage you’d never mistake this for a New England autumn postcard.

Things were nearing the end of leaf-fall. Most of the leaves lay underfoot.

Some of the leaves that weren’t underfoot were underwater.

With most of the leaves now off the trees, the light-colored bark stands out. Here a tree shows off its silhouette against a dark green evergreen live oak.

Looking closely at the bare trees lets you concentrate on their peeling bark. Who needs inkblots when you can do your own Rorschach test on patterns of sycamore bark? It’s great now, but will get more interesting as the year progresses.

Yellow, brown, gray and green are the main colors this time of year in the canyon bottoms where sycamores concentrate. Here’s a final shot of the last yellow-brown sycamore leaves of the season.

Nearby, cottonwoods contribute to the color scheme…

…as do the arroyo willows.

It won’t be long before the raucously colored flowers start up. But it’s a quietly beautiful time of year before they do.

I was confused the other day. Walking by the young plum tree, I noticed this. Flowers? In November? Apparently the plum was confused too.

After the long summer doldrums a lot in the garden is finally showing signs of waking up from its long nap. Some plants are showing new growth, others are blooming–even blooming when you don’t expect them to.

These paperwhite narcissus are a reliable indicator of the cooling days and nights ahead.

Protea ‘Pink Ice’ coexists with the most xeric plants in the garden and stays a resilient green all year. Beginning in the fall this big shrub begins its flowers. This will go on all winter and into the spring.

Salvia clevelandii’s main flowering happens in the spring. But given the right conditions–a little supplemental water doesn’t seem to hurt–it can throw a few more flowers in the fall.

Ditto for Salvia spathacea. Sometimes a lot is made of the repeat-flowering abilities of some of the natives. With these two, the spring flowerings are always way more stunning, and you’ll never confuse spring for fall. But as reminders of the late winter and spring flowers ahead, they’re terrific.

Another seasonally confused plant is this groundcover ceanothus. I’m only slowly now coming around to this genus. Groundcover versions like you see in the Burger King parking lot (think C. griseus ‘Yankee Point’) were all I saw for decades, but I’ve been trying to pay more attention to what other ceanothus have to offer. This one, unfortunately, is one of the Burger King-type varieties: low, flat, green all year on a low-to-moderate amount of water. It’s so inert and emphatically green it reminds me of plastic. I may never come to love this type, but fortunately there are other plants in the genus that do very different things.

My campus is incorporating more natives into the landscaping, and all these photos of natives, from the salvias, down, come from an afternoon walk yesterday afternoon. Here a young plant of one of the dendromecons (either D. rigida or D. harfordii) provides an airy cloud of yellow.

…and nearby one of the heucheras celebrates its spot in half-sun with occasional irrigation.

A few flowers, for sure. But it’s not really spring. We’ll need the rains to begin for that to happen.

Here’s a nice house in the Hyde Park neighborhood as seen from the bus. Notice the wintry-looking bare trees. Brrrr, cold, said the California blogger.

Though nice, the house isn’t a major architectural landmark. However, as of last month, it became an important historical one: This is the non-White House residence of Barack Obama. Actually, it’s the side of the house. The road on the front side has been sealed off by the Secret Service.

That in part sums up the experience of visiting here in the winter. There’s a lot of stuff that would be really interesting–if only it were open. Or you see stuff that’s maybe not looking its best.

Still, there are at least a couple bloggable things I’ve run across that I’ll be posting after I return home. If only this were May, when the gardens are looking more extravagant and the garden bloggers will be convening for their Spring Fling…

A closer look at the flowers…

…and a closer look at the leaves of the aloe (serrated edges, much softer than they appear) and the agave (straight edges).

For some people, it’s not winter without seeing snow. For me, it’s not winter until I’ve seen the aloe. Okay. I’m ready for spring now.

Friday, on our return home, John and I stopped by the Getty Center for an exhibition of the photographs of Carleton Watkins (more on that show in a future post). To visit the Getty without taking in its gardens would be unthinkable, and we spent more time outdoors than we did in the galleries.

It had rained the previous two days, clearing out the garbage in the air. The views from the hilltop were spectacular. Here you can see the skylines of Century City in the foreground against downtown in the distance.

This is the view to the southwest, across Santa Monica Bay. The distant land mass (straight ahead and to the right) is Catalina Island, forty-plus miles away.

The visit last Friday was the first time we’d visited the gardens of the Getty Center during the winter. The Robert-Irwin-designed Central Garden advertises itself as “always changing, never twice the same,” so this would be a good chance to see it during a time that was less pornographic with flowering plants.

Still, there were flowers. This is the core planting of clipped azaleas in the central water feature. In fact this was the first time I’d been there when the little mazes were showing any flowers. In addition to the blooms, the foliage of one of the two azalea varieties darkens and reddens in the cooler winter weather, making the planting appear to be comprised of interlocking rings of different plants.

If you click on the image to enlarge it, you’ll see that the plants could stand a little bit of clipping. The azaleas are little floating islands in the water, so keeping them trimmed involves a little more than strolling over them with hedge clippers.

John’s aunt volunteers at the museum, and once she’d asked one of the groundskeepers how they trim the plants. At first he mimed getting in a boat and rowing to the azaleas. Then, after pausing for effect, he grinned and said that the water was really shallow, and that they actually just donned some waders to do their work.

Aside from the azaleas, there were just a few other things in bloom: bougainvilleas, brugmansias, roses, eryngiums (sea-hollies) and some winter bloomers. Most of the interest came in the form of foliage and stems.

Here are some details from the plantings that emphasize color, form and texture, most of it best appreciated at close distances. Some of the color combinations rant toward the monochromatic. Here gray succulents contrast with the black leaves of Ophiopogon planiscapus.

This one featured yellow and green.

The foliage here tends more towards the bronze end of things.

In this composition, the silver-leaved Dichondra argentea is being slowly out-competed by the red oxalis (probably a red-leaved form of O. pupurea). Once the weather warms, the oxalis will die back, letting the dichondra regain its dominance.

Some of the color combinations were more varied.

Some plantings ran towards the chaotic. Like, don’t you think the blue aster-ey bits in this planting (lower right) are a little too over the top? I think the light gray leaves would have added a nice contrast to this combination. But the flowers… Gild the lily, why don’t you?

But, hey, it’s all taste isn’t it?

In a nod to the season, several specimens of browned late-season grasses moved dramatically in the strong midday winds. Before you go getting any ideas that this was a planting in the heightened naturalistic style of the New Perennials garden designers like Piet Oudolf, the grasses were single plants of contrasting species, placed in pots placed along the walkway.

In this last photo, in contrast to the preceding pictures of winter grasses, two plants with somewhat grass-like forms belie the fact that it’s winter. To the left is the restio, Chondoropetalum elephantinum, and the right is variegated society garlic, Tulbaghia violacea.

Some garden designers would like you to be able to know exactly what season it is by looking at the plants in the garden. Following this philosophy you should be able to set your calendar by looking at the garden. But what gives away the fact that it’s winter in this photo are the two visitors, bundled up against the cold. Looks like winter to me!

And you know what that means…only four years to go until 12–21-12, the Mayan End of World, as baktun 13 comes to its close!

Apparently the Mayans didn’t have Hallmark stores where they could buy themselves new calendars…maybe something light and fluffy with kittens or puppies or blooming daffodils on it…

At least the Mayans were in tune enough with their environment to end their calendar on the shortest day of the year. For those of using this Gregorian calendar: Where’d we ever get this December 31 end-of-the-year nonsense? What does December 31 have to do with the natural world? The Gregorian calendar is a boondoggle invented by several centuries of committee meetings if there ever was one!

Suggested soundtrack: R.E.M.‘s “It’s the End of the World as We Know It.” Or, for a viewing suggestion: Wim Wenders’ epic film, Until the End of the World (which happens to use the R.E.M. song).
