Tri-Met’s Orange Line Landscapes: Clinton & SE 12th to Harold St.

This shows the banded pattern common today in long mass plantings each swath a single species.

This shows the banded pattern common today in long mass plantings each swath a single species going for a kind of landscape scale ‘graphic’ pattern that is less concerned with ‘fit’.  This is near the Clinton/ SE 12th stop.

Size matters.  In horticulture it changes everything.  Things that are inconsequential, or maybe even enjoyable in the backyard garden, can quickly become daunting or onerous when the scale is ramped up.  Working at a commercial or institutional scale has to change your entire approach to the landscape.  In a small garden it is easier to accommodate mistakes, the conflicted combinations and those issues of horticultural ‘fit’ that we missed when we design or install.  Scale, however, rubs our faces in it everyday, makes us pay with aching backs as unintended consequences play out across the thousands of sq.ft. and acres.  It becomes a matter of physical survival and undermines your professionalism.  You become perforce part laborer, part diagnostician, designer, plantsman and critic….Out of necessity you sharpen your critical thinking skills and the last thing you ever wanted, your sales skills, as you work to sell your ideas to management who are absurdly ignorant of the problems you face everyday in the field.  And, then, eventually, you retire, but you don’t turn it off…you can’t.

Which brings me to the MAX Orange Line and its landscapes.  When I did horticultural design review for large capital Parks projects, it often felt like a dueling match.  I would pour over the design, whatever the stage it was in, match that with my particular knowledge of site conditions and my maintenance experience within Parks.  I would state my concerns on paper and in meetings with the Project Managers and Architects.  I was stubborn and consistently found myself up against a process that undervalued horticulture and my input.  Good horticultural practice was regularly placed in a losing position opposite not just that of the Landscape Architects but of a very political process that tried to give the public what it wanted as long as it fit within the Architect’s vision.  Horticulture always came out a poor third, even though good horticulture always saves money in the mid and long runs.  It was exasperating.  The public, by and large is ignorant of horticultural practice and no effort is made to educate them at any level.

Revisiting Holgate Overpass: A Mistake Repeated

Holgate Overpass - the northeast approach. This was taken Aug. 28 of the landscape cut down in April showing regrowth in a hot drought year.

Holgate Overpass – the northeast approach. This was taken Aug. 28 of the landscape cut down in April showing regrowth in a hot drought year.

Holgate Overpass Update:

It finally rained this last weekend!  Somewhere around .3″.  Woohoo!  It will be the most rain that we’ve received since March.  It’s been dry!  In April the City cut down the ‘weedscape’ on the northeast approach of the Holgate Overpass.  It’s rained very little since and we’ve had record warm temperatures all summer.  No one has come back to spray, plant or do anything.  No one’s even picked up the trash.  If you compare the four ‘weedscapes’ on the two approaches they are very similar.  The NE, by volume has had the most regrowth.  This is for two different reasons: first, this site was cut earlier in the season when there was more moisture still in the soil to enable regrowth, and secondly, because the site is dominated by Blackberry and Tree of Heaven, both perennials, well established and of larger stature than the plants dominating the other approach landscapes.

Weeds, Patterns and Pokeweed

It’s true, the longer that you garden, the more you realize that you have to learn! And, that sum total of bits and factoids to learn in the garden universe, is itself changing over time! Gardening can be a ‘wild ride’ through a dynamic and evolving world. We can never have it all figured out!

Gardening in Parks has you building these relatively long term relationships with multiple sites. For sometimes slow learners like I can be, this broader scope can give you different insight into change in the garden. Different soils, different histories of use, different plantings trundling down the path of time in often times very different directions. On one site plants perform well with little conscious intervention on our part, while on others, they struggle or even die. As a home gardener you see this when you visit the gardens of others, but it’s a different relationship and you don’t really know what has gone into the development of someone else’s garden.
