For years my client and I had been looking at a certain giant blob of a thicket on her property. Lanky buckthorn, lilac and other unkempt and untended shrubs had made the space impenetrable. The fact that the area was on a steep slope made investigating what was there all the more difficult.Not knowing what was in there made it easy to just mow around it, and act like it was part of a landscape. Every so often she would talk about what might be in there; this went on for some years.
One day she called to say she had clear cut the entire spot, and discovered an old rock waterfall and pool. No doubt it dated back to the 1920’s. The precipitous drop, lined with giant rocks, was entirely stable. There was a lot of discussion about restoring the watefall and pool, which led to some discussion of a new fountain; more years went by. One day she called to say she wanted me to look at the space again-I thought as the thicket was threatening to grow back-we were being chased for a plan. How like her to install an enormous concrete and wood sculpture in the center of the old pool. This is so distinctively her way of working things out. Making a move like that was forcing everyone’s hand. I told her I thought a sculpture of this size and proportion needed its own park.
The sculptor had sunk concrete pilings in giant sonatubes. Still visible in the above picture, it was apparent no small amount of grading was needed. My client was concerned that the pool would hold water. The rim of outside soil needed to be taken down. A giant pile of rocks collected from the first clear cutting went into the hole first. Trapping water near the sculpture would not be a good idea.
A skid steer made quick work of removing the weedy growth that had begun to take hold. I have watched the history channel television series called “Life After People” with great interest. It is astonishing how little time it takes for untended ground to go to rack and ruin. Nature abhors a vacuum; any bare dirt will have something going on in short order. Ignore a space, and nature will take over in your absence. 
The front edge of the old pool was lowered to permit water to escape. I so love this point in a landscape project; bare sculpted dirt is incredibly beautiful. A landscape of evergreens planted in sculpted, cultivated soil-a landscape of my dreams. Barked areas in a garden leave me cold-I like to cover the ground with plants, or see dirt. I mulch strictly to conserve moisture in the soil. The pattern of light and dark on the ground here is telling. The old waterfall and pool were situated in a patch of sun. The sculpture benefits from this.
New lawn softens all the hard edges. The rolling, swelling and dipping of the ground makes for a big fluid situation for the starkly vertical sculpture on its big legs. They look good together.
The fountain rockwork we left exposed. It is a part of the history of the property. Practically speaking, I would never have removed those giant stones; they have stabilized soil existing at a very steep angle. In the spring, my client will be able to pick and choose what she mows, and what she chooses to let be. There is a sculptural element yet to come-the decision about how and where to cut the lawn.
The old stones and the new concrete seem entirely compatible in their contrast. They wrangle with each other. The park is big enough to invite serious viewing. I am seeing that vaulted roof this morning as if for the first time. I need to write my client a thank you note for making a mark, and setting that sculpture amidst the weeds and the history, so as to say what now? Am I not lucky to have her?
What could be better than a giant pot stuffed to overflowing with nicotiana? OK, probably plenty of things, but no doubt I am a big fan of the nicotianas. There are a number of ornamental tobaccos suitable for cultivation in our area. The species nicotiana alata pictured above grows strongly to 30″ or better. It has a loose, rangy, and unstructured habit of growth. Sporting clusters of big leaves at the base, the flowers appear all along thin soft stems. They are indeterminate bloomers; a stalk will continue to elongate and produce flowers for months. Once a stalk blooms out, and starts setting seed, I trim it back. 
A pairing with Panicum Virgatum Dallas Blues makes that grass all the more icy blue in appearance. Grasses can be difficult to do well in a container, as they are stiff, or awkwardly floppy. Nicotiana makes for a graceful ruff here. They are not without their problems, however. The sticky soft succulent stems are a magnet for aphids. Their giant basil leaves sometimes need pruning back when they threaten to smother something else growing at ground level.
But by far and away my favorite is Nicotiana Mutabilis. It grows tall, and billows out over any edge with a cloud of small flowers that dance in the slightest breeze. Can you tell I like it? The flowers range from white to cream to pale pink to rose pink. This big thing requires secure staking from the beginning. It will pick up speed, and send out new growth from the base of the plant as the night temperatures start to cool. 
They are a nuisance to keep deadheaded-I don’t fuss so much with that. Its hard to spot which stems need headling back, and every part of the plant is sticky. This seems a fairly minor problem to me; a well grow stand of mutabilis is enchanting.
You can see the new growth pushing from the base of this pot on both sides; all of this came on strong in September, and will continue until a hard freeze. They also seem much more aphid-resistant than other nicotianas.
The individual flowers are so small and so delicate; the overall picture is delightfully meadow like. All of these nicotianas are a staple of my summer garden.
On my top ten list of frequently asked questions, the culture of evergreens in pots ranks right up there. In theory it sounds great. You invest in an evergreen which will provide you with a center of interest that looks great no matter the season. Perhaps there will be room on the edges for a few seasonal annuals. The work and expense up front is considerably more than planting smaller and less expensive plants, but then you are done. Redoing one’s pots with new plants every new season no doubt is a lot of work and expense. But as with everything connected to growing a garden, one is rarely “done”. The Italian cypress in the pot pictured above is not hardy in Michigan, nor can one leave a terra cotta pot such as this one outdoors during the winter. The cypress has to be wintered in a greenhouse cold storage area, and replanted every spring. The pot is put away. There is time and trouble hauling it back to the greenhouse in late fall.
This 25 year old rosemary has spent 25 winters in a glass house. It is an evergreen-should you live in Greece or Italy, or California. Michigan winters are fiercely cold. However unfair it seems, rosemary is just not hardy here. In return for the extraordinary pleasure of owning an old rosemary such as this one, my client is willing to weather what it takes to keep it alive and healthy.
Mugho pines, both the shrubby and the topiary forms, have the reputation of good survivability in pots. Critical to that survival is proper watering. Should you quit watering this evergreen when your geraniums go down from frost, you are almost certain to loose it. Judicious watering right up until the soil ball is frozen solid is a must. If this evergreen were to unfreeze in a January thaw, a watering might be in order. When the soil thaws in the spring, the watering should be resumed-even if this is long before you plant your other pots. What evergreens in containers require is not for the faint of heart.
This grand old myrtle topiary was beautifully maintained, for 11 summers. The 12th winter in the greenhouse, a furnace went out, and it froze. It has been in the greenhouse for the past two years; we are trying to coax it back to health. Owning plants like this is a big committment with little in the way of any guarantee. Just because you have provided next to perfect care for a long time does not mean you cannot loose it. Evergreens in containers are for gardeners who relish risk.
These mugho pines on standard have lived in these orangery boxes for 6 years. At some point, they should be taken out, root pruned, and reset in fresh soil. They will most certainly decline without this maintenance. No plant stays the same, just because its container stays the same. Plants will prosper and grow, or sulk and decline-one or the other.
Boxwood is a good choice for a container. As this French terra cotta pot cannot be left out, I wheel this entire assembly into the garage for the winter. This species, Buxus Microphylla, is very tough; my hedge on the southside of my building never winter burns. In the same spirit, it tolerates a mostly dark and unheated garage from November until March. At the first sign of moderating temperatures, I take it back outside. A garage can get too warm for holding plants dormant long before the outside temperatures moderate.
Waxleaf privets are an aristocratic cousin of our hardy privet. The large leaves are lustrous and juicy looking. They are hardy in zone 7, so they can be wintered in an indoor spot without much in the way of heat. They grow slowly, and are available in big sizes; there is demand for the topiary forms from gardeners in more temperate regions. They take well to pruning and shaping.
