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.

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
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.

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
(I wrote this several years ago for the HPSO Bulletin, when it was actually printed on paper, and thought re-issuing it today, edited and expanded, might be helpful to some as we are about to enter their flowering season. The iris pictured on my Blog’s masthead is Iris x pacifica ‘Simply Wild’ poking out from the base of the Chilean shrub Fabiana imbricata ‘Violacea’)
Gardening is no more or less subject to the vagaries of fad and fashion than the other activities we dabble in. Marketers prey on us luring us with plants possessing new and alluring characteristics, promises of larger flowers, more disease resistant, floriferous, more exotic or environmentally responsible, less maintenance intensive… the list goes on. Gardening is a very personal endeavor and as such we will always be subject to such Siren calls. There will be the righteous amongst us convinced of their own focused vision who seem to be immune (but what, we might ask, are they missing?) and there will be those who simply surrender completely to the beauty and bounty around them making themselves easy prey. In the long run, who is to say who is right? Our knowledge is imperfect and we are weak…. The act of gardening strengthens us, provides us with the opportunity to learn and in so doing puts us into relationship with the living world around us. We become better gardeners capable of making better, though still imperfect, decisions. Whether we garden to augment our own diets with what we grow or are trying our hand at healing a small piece of a damaged earth, or building a place of respite for ourselves and friends or trying to model ‘right’ behavior for our children and neighbors, we are out in our gardens and landscapes learning something of how incredibly complex this earth is…and that is all good.

The Pruning Series, 3
Plants often present pruning challenges to the gardener. I’ve already introduced the issue of understanding ‘why’ you are choosing to prune, the physical structure of a ‘normally’ growing individual and how it will respond to the cuts you choose to make. There are several good books out there that discuss how and what constitutes a ‘good’ individual cut and what approach you might take with different types of growers…it should be the goal of any gardener to understand the technical details of pruning, so that they become ‘natural’, reflexive. (In an earlier posting, I discuss pruning tools and provide an introduction to what constitutes a ‘good’ pruning cut.) Like all artists we develop a style that may distinguish us from others. Even understanding all of this and possessing the technical competencies there are the ‘aesthetic’ decisions the gardener/pruner must make. Two different gardeners can prune in the same landscape and it can be obvious when they are finished that they have very different aesthetics. The results can be ‘disjointed’ or harmonious. Every plant, every branch, every internode, presents a choice and because each individual plant of a given species or variety, though it may grow following a shared genetic code, will grow uniquely in response to the physical conditions it faces…and the damage and pruning it has received over its life. Like most things in life our control of a plant is limited and the more we attempt to control it the less like itself it will be. Continue reading
