Choosing the right plant is not an easy process. We pick a design theme, make sure our plant choices are a good match for our site conditions, are compatible with their ‘bedmates’ and won’t become overly burdensome, in terms of the maintenance we are able and willing to perform. There are a lot of variables here. Our expectations of how a plant performs in the landscape, as individuals and as a composition, are important as we assess their performance over time and decide how we will respond to them. Many of us are attempting to create gardens that require less of us in terms of maintenance, that fit the conditions on the ground with minimal intervention on our part. We may chose to create a xeric garden to minimize or even eliminate supplemental irrigation. If we do, the plant choices we make, their spacing, the size of plants we purchase, even the timing of the planting and the soil prep we do, are all important in our success or failure. While we attempt to keep our specific site conditions and our goals in mind, we need to be prepared for the extremes of conditions, like weather, that can occur occasionally, even if only once every several years.

Many of us who garden in the Pacific Northwest, and especially those of us in Portland this year, will be visiting our garden centers and favorite nurseries this spring and summer with a little more anxiety and need as we look for plants to replace those that have succumbed to this winter’s cold, ice and snow loads, all of which were more severe than what we have come to expect here. But before we pull on our boots and don our rain gear to head off for shopping there are several questions that we need to consider before we make our purchases. Not all of us draw up plant lists, but most of us at least carry in our heads a wish list of plants we have seen in other gardens, in magazine spreads and while on vacations, but if we want to avoid some major mistakes and move our gardens toward the kind of landscapes that we really want, we are going to have to put on our reality goggles and critically assess our choices…that is, if we want to avoid unnecessary losses in the future.

[There is a recurring theme in several of my postings and that is the failure of various of our local agencies and departments to responsibly care for the landscapes that they are charged with, a responsibility that is secondary to their primary mission and priorities. The fact that this problem is so common is indicative of two things: first, that society views the ‘care’ of the wider landscape as a non-issue, that it is either somehow self-regulating, the mother nature thing, or, of such low importance that it need not be addressed, or some combination of these two, and, that our need for government accountability is so tightly defined and our mistrust of it, so deep, that our ‘exclusionary’ strategies utilized to accomplish this, eliminate the possibility that secondary responsibilities, i.e., those not directly serving the explicitly stated priorities, are excluded from any action or even discussion. Thus, an agency or department charged with specific transportation priorities will only respond to and act on issues of transportation efficiency and safety…not landscape concerns. My position is that this allows the uncontrolled spread of weeds and an overall decline of the health, beauty and vitality of the landscapes across the City within which we live, devaluing both the place that we live and the quality of lives we can enjoy.
The following is another example of one such landscape, in southeast Portland, this time a one block section of unimproved right-of-way, or roadway (UROW), a scenario that repeats regularly across this part of Portland, the difference being that the lack of vehicular traffic and the grade have allowed this property to grow in solid and has become impenetrable. Many other such properties are in use by vehicles with sections of them graveled and eroded, huge pot-holes turning them into obstacle courses, but largely free of heavy weed growth, or at least free of many of the larger more aggressive invasives that plague our area.
First, below, is a descriptive piece that I sent to Commissioner Novick’s office as well as Suzanne Kahn, PBOT Maintenance Group Manager. Next is the response I received from Cevero Gonzalez, Constituent Services Coordinator, with the Portland Bureau of Transportation and finally, my interpretation and response to that. Governments are very ‘conservative’ organizations and are risk averse, meaning they tend to do what they’ve always done avoiding creative solutions that put them outside their comfort zone. Very often this is exactly what is needed.]
There’s a short strip of ‘street’ a few blocks south of our home and garden at SE Schiller between SE 28th Ave and 27th. It appears to have never been paved. It’s not currently passable by vehicles of any type without engineering and improvements. It’s completely overgrown with several invasive plants and multiple weeds all of which have been left on their own for years providing a significant source of ‘infection’ for the neighboring properties. It is also a repository for trash. From maps this appears to be a City of Portland property. Continue reading
About a year ago I posted a series of three articles on Tri-Met’s landscapes along the new Orange Line. They were a critical assessment of their design with many photos and explanations for my criticisms. I had a brief correspondence with the project manager after the first two before he stopped responding. I had asked about the maintenance schedule that they had with the contractor who would be doing the work. I did not receive it. Part of the reason was mine, as new ideas came up for me, my interest wavered and I moved on. Still, I’ve never received anything. Now, a year later, I decided to reassess the first portion of the landscape that I wrote about, as it is a section I regularly walk and ride by bike to downtown or to just get out. I would encourage readers to see my previously posted reviews. Continue reading

Landscape is the setting, matrix and backdrop for everything that we do as humans. It is where we live, work and play, the places, on which the infrastructure that enables our modern day life, exists. It is both essential and peripheral, always present and, too often, taken for granted, so much so that we often view it incidentally. Like many other things in our lives it may go unnoticed until it is so degraded that we can no longer ignore it. Overall, our care of it, reflects a similar low priority. It becomes largely ‘invisible’, behind the more recognized needs of a modern City. Individual mobility, food, water, shelter, energy, economic opportunity and growth, the transportation infrastructure that keep us supplied with these things, all and more take precedence, the landscape subsumed and secondary, inferior and problematic. Overall, it is not generally viewed today as having inherent value. Its value, as a living system that allows and enriches biological life, seems almost irrelevant as we are able to satisfy our needs and desires via the economic engine that propels us along. The landscape, nature, seems relevant only in so far as it can meet our recreational needs providing us a base on which to build and resources that we can manipulate/convert to satisfy our ‘needs’. Lost in all of this is our relationship with nature, with the landscape, its essential role in the creation and sustenance of all of the resources upon which we and the rest of life depends, and so, it has suffered. We have lost the ability, or willingness, to use nature as a gauge that shapes all of the other decisions we routinely make in order to meet our ‘economic’ needs. As both a society and as individuals we have learned to see these as separate and unrelated, so we routinely neglect the landscape. The problem is pervasive and integrated with how we live our lives. To correct this we must first acknowledge this and address it on many fronts. Continue reading
(I’ve made earlier postings on this topic, but this piece actually predates those. I wrote this in 2013 while still working as a horticulturist for the City of Portland Parks and Recreation as a member of a Bureau committee that was working to define ‘sustainable landscapes’ so that we could begin to make our policies and practices more consistent with our ‘desire’ to create sustainable landscapes and protect the relatively intact ones that remain. This was a difficult process. We spent a lot of time discussing/arguing about what constitutes a sustainable landscape and ultimately the direction that Parks should be headed.
There was a large divide between those of us who saw ultimately, that the only truly sustainable landscape was one that recreated those native landscapes that preceded the massive changes that European Americans brought with them, so that our efforts should be on these, and those of us who, having spent much of our professional lives in the field doing maintenance in created/urban landscapes, arguing that these new landscapes played a necessary role in the modern world and that our designs and maintenance of them could be moved in a more ‘sustainable’ direction. These urban/functional landscapes, whether for active sports, community gardens or even many passive uses, provide places and venues for activities that native landscapes cannot.
The organizational structure of the Bureau has been built around three primary landscape ‘types’: ‘natural landscapes’ which tend to be larger and border more densely populated sectors of the City, ‘contrived landscapes’ that are dispersed throughout the City and serve the more traditional Park functions for sports and more casual social use and the ‘enterprise landscapes’ of Golf and PIR that serve very narrow functions and depend on those uses for much of the revenue that supports them. These are operated and maintained by discrete groups within the Bureau, have different cultures and priorities and view sustainability very differently. Because these are all in a highly urbanized area the degree of historical disturbance and the continuous pressures that a concentrated population apply to them, they can never by truly ‘sustainable’ in that they will always require our active stewardship to counterbalance these pressures. This is not to say that we give up on the idea of balanced/dynamic landscapes of appropriately chosen plant communities. We just need to remember that these are urban areas and be good stewards of the land. We can even move ‘high use’ landscapes in a more sustainable direction, both in their design and in their maintenance. It is incumbent upon us to do this to ultimately minimize the pressures put upon them and natural areas by weeds, invasives and human use.) Continue reading
The following is intended as a template for action or a beginning point for a discussion that is long overdue.
Landscapes are more complex than most people realize. They can go seriously awry in a very short time. Undisturbed native plant communities are relatively stable and are able to respond on their own, as they have for millions of years…if the disturbances they suffer are relatively small. Unfortunately these plant communities have been decimated in urban and most rural agricultural areas severely compromising their abilities to respond in a positive and effective manner. The addition of invasive species to the region puts even stable, undisturbed plant communities at risk. Because we are not all ecologists, or even gardeners, what can we realistically do to stop or reverse this process of landscape degradation? The decline of our landscapes is linked to a long history of practices that have ignored the value of both our native and contrived landscapes, a belief in a right to ‘dispose’ of the land in whatever way we so choose and our denial that this destruction matters. We have done this through our land management practices, our designs and the uses of the land itself even those that may seem unrelated, many that have become automatic in our society and are directly related to how we live, work and play today in the modern world. Our active threat is inherent in the way that we do business. Our attempts at correction are, too often, limited to only slight modifications that do not put any undue ‘pressure’ on our local economy, business or the privileges that we have come to see as ours. We are a society that has, in short, become disconnected from the realities of life at the local level and what is required to support it. We see a limitless nature that is there for our use. Whatever we may need, we believe that we may merely buy from elsewhere, an elsewhere that is limitless though undefined.
To turn this situation around, or to make significant improvements, requires that we examine what we are doing now, that may be working against the goals that support life and landscape,…and stop. We have to stop doing the things that are working to continuously disrupt the ‘healthy’ functioning of the landscape. If we don’t do that then all of our attempts at improvement, all of our tweaking of our system, will come to nothing. We cannot ‘save the patient’ with good thoughts while they bleed out.
