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.

Public Landscapes (active urban contrived) Horticultural Management
Public Landscapes (urban plant communities)
Corridor Management: Transportation and Riverine
Division of State Lands
Multnomah County Bridges
Outreach and Education
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
I’ll bet you thought this was going to be about the hours of meetings wherein Council pours over the issues surrounding the plantings and landscapes of which the City has responsibility…Hah!!! No, this will be a bit more mundane, hands in the ‘dirt’, and about some of my experiences gardening in the limited ground around City Hall, as well as some observations and comments on what it’s like to garden in such a public spot. There’s also a bit of hand wringing and hair pulling here. I’ll be telling two short stories of gardening, one on the 4th St side, but first the 5th Street side of the building. Continue reading
The Fields (Click here to see the final design plan), completed in spring of 2013, is Portland’s newest Park in the north end of the Pearl District. While I was still with Parks I did the horticultural review during the design process and was an on site inspector, periodically, during construction. New Parks like this one require a huge time commitment by Parks. Selection of designers, outreach to all of the stakeholders and many other meetings involving more technical aspects of such a project all in an effort to deliver to residents a Park that is beautiful, serves the needs of residents and is affordable in terms of long term maintenance. Before the project is offered to the design community functional goals are set for the Park and a general design theme is chosen. Various firms offer proposals. Concepts are bandied about. Eventually, one is chosen. In this case, the Office of Cheryl Barton, a San Francisco firm, was awarded the design contract (To see what they have to say about it). Continue reading
Jefferson Circle lies at the south end of the downtown seawall in Tom McCall Waterfront Park helping to anchor what we always referred to as ‘the bowl’, site of the Dragon Boat races, July’s Blue’s Festival and the end of Summer Oregon Symphony performance. The curving slope of the lawn that sweeps across the site assures attendees of a more clear view of the stages erected for big events. Jefferson Circle and ‘5 Flags to the south, permanently ‘backup’ the temporary stages, while a third display bed, Columbia Circle, marks the main entry from downtown on the west. All three beds share a common theme though they are by no means a mirror image of each other.
These three beds were part of Waterfront’s original design from the ’70’s. Jefferson Circle an actual circle 40’ in diameter defined, like the others by a concrete bench that surrounds it. Columbia is an ellipse stretched along its north/south axis, while 5 Flags is an ‘organic’ form with 5 ‘corners, each defined by a flag pole that for years displayed ours and a changing assortment of three other international flags. Their plantings have changed over the years. I take responsibility for their current theme and most of their plantings. Continue reading
