On Choosing Salvias for My Garden

Salvia confertiflora in the San Francisco Botanical Garden, October

I can’t get Jimi Blake’s HuntingBrook Garden out of my head…that’s a good thing, though a little odd since I’ve never been there. The images and ideas, the energy that both Jimi and his sister, June, who gardens nearby, projected at the NPA Study Weekend was infectious and inspiring. Their gardens are both beautiful and, obviously, central to each of their lives. They are dynamic, like the minds of each of them, endlessly creative and curious…botanical dabblers of the highest order. Apparently, their gardens don’t stand still.  No plant or bed is ‘safe’ from revision, in part or from wholesale revision.  I have no pictures, their’s, however were gorgeous and seductive. I have to rely on the few they have posted to their websites. Please, go to them.  (Jimi’s HuntingBrook Garden.)

Of the two, Jimi spoke first, his topic, Salvias, those that he’s found to be worthy of a place in his garden.  With such a relatively large garden he can ‘trial’ many plants, and, if you’re like Jimi, evaluate them in terms of both aesthetics and performance.  He loves Salvia…there are nearly 1,000 species and who knows how many hybrids and selections!  He grows many from seed, others he’s rooted from cuttings, like minded Salvia-philes gift him with treasures and Jimi works them into his beds, artfully.  You won’t see any sterile lab like rows, he trials them in mixed borders and beds.  In Seattle he presented his ‘winners’, 33 different species, hybrids and selections.  The list is comprised primarily of plants ‘durable’ enough for his conditions with long bloom periods…with a few exceptions, late bloomers, and those of short duration…need not apply.

On Being a Defacto Pteridophile (fern lover)

This is the NW corner of my garden where I’ve tried many of my ferns. Palms, the fence, our bamboo and steel pagoda and a large Mahonia x media provide more shade than most of the garden ‘enjoys’.  Some of the ‘squirrel tails’ of my Sanguisorba hakusanensis hangs in the foreground.

How many different species and cultivars of a particular plant group do you ‘need’ to grow before you can be said to have a serious problem? I am not an ‘Agave-holic’! Isn’t a statement like this, one of the surest signs of such an affliction? I know other people who grow a lot more of these! What does it mean when you persist in growing a group of plants in spite of the fact that many of them die? And what constitutes too many? It can’t be a set number. If a group comprises comparatively few plants when compared to Orchids say, a group of over 20,000 species, growing a 100 plants might seem obsessive, while in the Orchid world it may not be. My name is Lance and I grow ferns…in a garden that suggests I should grow something else.

The one healthy frond left on my ‘rescued’ Woodwordia unigemmata.  This single leaf is almost 3′ long.

While at the NWPA’s Seattle Study Weekend, I noticed a couple of ferns in particular that I have in my own garden, only growing much better, apparently vigorous and ‘carefree’, including Woodwardia unigemmata and a couple of different forms of Asplenium. One of the first things I did on my return home was to dig my own Woodwardia unigemmata. freeing it from the thirsty roots of my neighbors Kwanzan Cherry. I did the same for a Dryopteris wallachiana which had also been struggling with too little water, only it was under my own large Parrotia persica and Actinidia kolomikta.

Asplenium scolopendrium ‘Furcatum’ happy near the gate growing with Asarum splendens. Aspidistra, more Acorus and an Astrantia also grow in this bed, but other genera, whose names start with a letter other than ‘A’ also abide in it.

Asplenium scolopendrium ‘Furcatum, the Fork Crested Hart’s Tongue Fern, pfeeew, whaat a name!,  is another very nice form of a beautiful species.  I saw various forms of this at the study weekend, all of them looking vibrant and neat.  The first of these I’d bought several years ago was the straight species and was devastated by root weevils notching its leaves.  With that exception, it has grown well for me.

The 2018 Garden Riots Awards for the Northwest Perennial Alliance Seattle Study Weekend!

Abies koreana, in Jim Gutherie’s garden, looking exquisite.

These are my own personal favorites for the Northwest Perennial Alliance’s Study Weekend in Seattle. This is not official, nor the result of even a casual survey of attendees, just my own selfish opinions….

All of the speakers were great!!! I mean this, seriously. I am not known for my PC’ness or empty platitudes. First, goes to the brother and sister team Jimi and June Blake from Ireland for their informative and infectious talks on their gardens and plant loves, for the attention that June brought to us of the history and unique contexts of the place where she gardens, her design sense and ways of working. I particular enjoyed Jimi’s understated wit and sense of humor and our shared plant sympathies, including his for Salvias and his many other favorites as well as willingness to tear into and completely revamp his own garden. If I’d only had the list of plants that they chose to talk about, that would have been plenty enough to have gotten my attention, but their abilities as presenters, as interesting people and characters, brought it all ‘home’. Loved the ‘blue’ Jimi. You’d never catch me dead in it, but on you…it fit perfectly. Continue reading

Cottonwood Canyon on the John Day River: Place, Plants and Experience

IMG_1077

Cottonwood Canyon State Park, near the campground, looking upstream toward the old Murtha barn and common buildings, the evening sun climbing the worn canyon sides. The Park retained some of the old ranch equipment.

Massive lava flows pushed around the lower John Day and Deschutes rivers over the course of several million years leaving them to find and carve new routes, often next to the very ‘plugs’ that filled their former canyons!  Today, deep below the layers of hardened basalt that form the palisades and ramparts projecting out in tiers from the smooth full curves that rise above us, we look through 15 million years of accumulated history.  The fine grained basalt shatters and fractures in line with their mineral structure under the forces of water, weather and gravity.  Sagebrush and grasses dominate revealing an oddly ‘netted’ pattern across the sloping canyon hillsides, lit by the often harsh sunlight, illuminating some kind of subsurface movement of the thin soils that soften the slopes.  The ‘net’ looks as if it had been draped across the land then stretched sideways catching and snagging on what lies beneath in a never the same, but consistent repeating pattern.  It shows best when the angle of the sun comes across the pattern, not when it hits it head on or when clouds make it too diffuse.  Coarse falls of shattered basalt spill down to the canyon’s bottom always seeking their angle of repose.  The sagebrush steppe plant communities cover the surface and in their richness and vigor speak to the soils beneath.  Along seeps and drainages cutting verticallly down the canyon’s face, spring lasts weeks longer, and species crowd in that you won’t see other than near the river.  The surface botanical palette in this way reveals what lies beneath…if one knows what to look for.  Cottonwood Canyon State Park is a great place to observe this.

Hiking at Riley Ranch Nature Reserve and Along the Deschutes River

It’s the edges, the margins, that always contain the most diversity.  Large expanses of unbroken landscape take a portion of their character from their scale, a vastness, that the uninterested can often view as monotonous.  Seemingly endless expanses of ocean, desert, prairies even forests, can lull some into indifference, a kind of blindness, in which they lose interest and fail to see the intricacy and richness of that which surrounds them….By overlapping two different landscapes places can take on a complexity that neither has alone…and may even arouse many of those inured to the natural world surrounding them.  Two different landscapes sharing a common edge can form ecotones, where each landscape contributes species in patterns not found across the vastness of each alone.  Cut a river through an arid landscape and it becomes altogether different often with stark changes within a few feet.  Such is the arid canyon landscape of the Deschutes River immediately north of Bend, OR.

Echium wildpretii in Bloom

IMG_9915

This Canary Island native has a tougher winter climate here to endure than back home.  As an alpine growing on Tenerife, this plant is said to tolerate down to 20ºF with its characteristic dry winters…not so here.  After a relatively mild winter here in inner SE Portland the later half of February chilled down with a little snow as shown here on Feb. 22.  The official weather station at PDX recorded nine days at or below freezing in February ranging down to 23F on the 21st.  This was a fairly ‘normal’ February temperature wise for us, though with just less than 2″ of precipitation, about half of normal, which could have aided its survival.  At my location in inner SE we can record 5-6º warmer than PDX though we often move right in step,  January was milder PDX recording below freezing temperatures on only two dates, the first and second…and we were right around freezing both of those days with just under 5″ of rain for the month.  During December we were ‘blocked’ from lower temperatures that hit most of Portland.  PDX recorded 14 lows below freezing, we suffered only six getting as low as 25º on one of them.

On the Demise of my Ensete ventricosum ‘Maurelii’ (Red Abyssinian Banana

And how did your Red Banana, Ensete, do?  Mine didn’t make it having left it planted outside until after Christmas. In my part of SE, December was mild, until the 26th or so, with lows just below freezing a few times. Then we were out of town a few days and it dropped into the mid- and upper 20’s. I had thought it was okay for awhile, as it pushed out a leaf while sequestered in the basement where I had belatedly moved it, but that is all that it was able to do.  It’s meristem, at the base of the plant, was damaged. I did the finger test at the top of what I had left in place of the pseudostem, about 4′ of it, and the core, through which new growth should have been pushing was mushy and smelled of rot. I cut it down with my machete in a series of cuts, illustrated here, and you can see the soft brown center surrounded by what appears to be healthy tissue. It was still able to push out a few white new roots over its winter storage. Apparently, the meristem is less cold hardy than the rest of the plant. If you could smell it you’d smell strong rot!!! After 12 + years I have found this plant’s limit! The last pic shows its dismembered carcass, reminiscent of the Tibetan Sky burial ritual, to dry away its stink before I dump it in the bin!

IMG_0519A few days later….This was the business end of my Ensete, Red Abyssinian Banana. You can clearly see that the starch storing rhizome, modified stem tissue, 12″ in diameter, is crisp, white and healthy!  I’ve split it down the center, top to bottom, through the meristem. The meristem, the site of cell division and the initiation of all top growth, is black, dead and rotting.  Each leaf begins here.  As new leaves form at the center, the older leaves ‘migrate’ outward forming the tightly packed ‘pseudo-stem’.  This plant, my plant, was unable to initiate any new leaves and with last year’s leaf blades removed, was dead on its ’feet’.  The rot would have continued to spread from the center out.  New root growth is also compromised.  It shares this growth pattern with other monocots much like bulbs.  In others, like the woody Palms, the maturing layers of tissue around their meristems, provides some buffering from cold as they caliper up.  Obviously Ensete are very limited in their ability to do this!
