Fabricating Arrangements For The Winter Pots

It is indeed that time again. This past Friday we swept out the garage at Detroit Garden Works, and set up our fabrication shop. The most useful and best part of the shop is its heat. Warm space to work makes for good and thoughtful work. So does good materials.  Rob works his heart out to be sure we have a huge selection of materials for our winter and holiday installations. His fresh cut twigs are the best I have ever seem. Farmed twigs, grown on great soil, mean all the dogwood and willow cut branches we have to offer have superior color and form. Every bunch features unblemished stems typical of the current years growth. Ron snapped up some very tall second year growth red twig which is equally as spectacular. Those glossy colorfully barked stems makes our winter container work easy. We construct forms that fit tight into the intended containers from large sheets of dry floral foam, layered up via hot melt glue.  One layer of foam goes below the surface. The upper layer gets stuck with greens, and whatever else we have in mind. At exactly the angle we like. Of course we save client’s forms from year to year. The above form is for a very large planter box. Note the exterior grade plywood at the bottom. That plywood enables us to transport this arrangement safely. As last year’s form had been reused for the past three years, we added a new layer of fresh foam to the top. The degraded foam goes to the bottom, into the pot.  The new foam gets top billing. This client has a decidedly contemporary view. Their winter container arrangements will follow suit. The center of this form was filled in with dark gray birch branches. More on that decision later.  David stuck every stem of fresh yellow twig dogwood, one stem at a time. I managed to capture him in the act. He is an accomplished fabricator. He knows to look to the airspace to tell him where he needs a branch. Once he claims a visual space for his branch overhead, he inserts that branch in that spot in the foam that puts his branch where he wants it. Does he ever look down at that branch is going into the foam? No. He is always looking at the overall shape from above.

I regret to say that our supplier of preserved and dyed eucalyptus has closed up shop. We bought out every bunch he had available, once we knew he was closing up.  We did have a few barrels of the color “Rain” available.  I liked the idea of those yellow twig branches faced down by this dark blue gray eucalyptus.

I decided to use the materials in a less formal way this year than last. This is a color palette I know my client will like, but changing up the style can make the most familiar materials look fresh and different. Winter arrangements with a simple and sculptural quality look great in all kinds of weather. In addition, this volume of branches will help to shed the snow, or at least keep it from damaging the overall arrangement. This is by way of saying that designing winter arrangements that can withstand snow is a good idea in zones that can rack up the inches in the winter. We will not dismantle this arrangment until mid March, so it has to be winter weatherproof.

This close up of the yellow twig set against the dark gray brown birch bunches on the interior illustrates how the effect of the color can be intensified by way of a contrasting backing. The addition of branches on the interior create the illusion that the form is tightly packed with yellow twig stems. The reality is quite different; there are just 2 rows of them. The matte birch stems also help make the yellow twig bark appear all the more glossy. A third reason for that dark interior?  In a subtle way, their darker color provide a transition from the dark of the blue gray eucalyptus, to the bright of the yellow twig.

A pair of round pots are further from the road, and nearer the house. I want the arrangements in the pots to appear brighter than the planter box. The interior branches in this case are whitewashed birch.

This yellow twig looks brighter yellow to my eye. That brightness will be compounded, once the arrangements are placed in the pots.

It made sense to stuff the rest of the form with variegated boxwood. This green comes to us in 40 pound boxes. The branches are long and densely twiggy. All of our greens are premium grade, like this.  It  means there is great scale, size and volume to every branch, and almost no waste. Greens intended for interior winter and holiday arrangements are generally small, and do not translate so well to use in pots.  We try to keep each stem intact, rather than cutting it up into smaller pieces. For a less formal arrangement, we let the natural grown branch be what it is.

The light gray branches are called natrag. That is the sum total of what I know about them, except that they have a very sculptural and exotic appearance.

The natrag was introduced into the arrangement only on the front and back.  They are so strong visually that more of them would dilute their overall effect.

The arrangements were done and ready to be installed this morning. In the foreground, the forms for our next project. My landscape crew generally handles the installation.  They have a great eye for positioning plants in the landscape.  This skill translates into installing these arrangements so they look like live plant material. If you look at the larger arrangement in the above picture, you can see that the blue gray eucalyptus looks almost black at the base. Part of the design was to deliberately create a shadow, and a sense of depth between the boxwood and the eucalyptus.

How we do this is very difficult to photograph, so suffice it to say that there is a 4″ wide band of incense cedar that is installed flat to the base of the form. An incense cedar moat, if you will. That space is what creates the shadow.

The eucalyptus and boxwood are both fairly tall. The cedar is inserted into the form on a horizontal angle, so it is barely an inch tall. I will post pictures of the finished installation tomorrow. For anyone who is new to our work, or has questions about the construction, I have posted many times over the past 9 years about them. You can click on and read my November posts from past years, if you are so inclined.

 

 

Recent Work

One of my crews has been planting fall containers full time and just about non stop for going on a month. I suspect we will be able to finish up by the end of this coming week. I am pleased that the warm weather has finally retreated. Really? Great seasonal container design is all the better for the inspiration that comes standard issue from nature. Our most colorful season is nigh upon us. The dogwood leaves have turned red and orange. The green leaves of the oak leaf hydrangeas everywhere are trending towards maroon. At the shop, the leaves of a single branch on the 5500 square feet of wall covered in Boston ivy are a brilliant red. This is a signal. Our fall season is underway. Cooler temperatures are a signal to deciduous plants to shut down their production of chlorophyll. Soon enough the green landscape will give way to the yellow, red, orange and purple we associate with fall. The rosemary in the above containers I would call a plant for all seasons. Planted in early April, these plants have grown on and still look great, seven months later.

Cooler temperatures means the ornamental cabbage and kale are beginning to color up. The color of their leaves will continue to intensify once the temperatures are reliably below 50 degrees. The most intense color will surface after a frost. That color will be more saturated after several frosts. Gardeners have a lot to look forward to. What you see in the picture above is a pale version of the the final mile. The changes to the leaves in the ornamental cabbage and kale as a result of dropping temperatures are part of the bigger process we call fall.That visual leafy change from summer to fall is the best reason for planting containers for fall. Should the experience of every season enchant you, bring that joy home. Pots at the front or back door, or on a terrace, are a daily reminder to enjoy the season at hand.

Ornamental cabbage and kale differ from the vegetable versions in several significant ways. Ornamental varieties form large flat rosettes.  The centers of these rosettes is what will eventually show color. The outer leaves stay green. The colder it gets, the more striking the color.  It won’t hurt you to eat ornamental cabbage, but the leaves can be shockingly bitter. You are on your own with that. Cabbage for consumption eventually form heads as part of their natural cycle of growth. Cabbage grown for consumption is mild. Cabbage meant for fall pots is all about the look of the leaves.  Kale meant for consumption evokes widely differing and strong opinions. Suffice it to say not everyone loves that taste. But kale representing in fall pots is about a visual discussion of the season.    The intersection of agriculture and landscape design is my most favorite place to be. Vegetables provide food. But the history and practice of growing plants for food contributes much to the ornamental garden. One obvious example is the corn maze. The availability of fresh sweet corn is a highlight of the summer. A field of late planted, late to mature corn bred and grown for silage with a maze cut into it is an experience of the farm enjoyed by many in the fall. This ornamental form of agriculture brings visitors to farms to buy pumpkins and apples at a time when their growing season has come to a close.  Interested in more information on local harvest events open to the public?   Michigan corn mazes

There are few fall container plants as showy as the ornamental cabbages and kale, but their true strength lies in their persistence. They are not only cold tolerant, they are frost tolerant.  I have seen them endure temperatures as low as 20 degrees without harm. Clients often ask me how long a fall planting will last. Each if our four seasons lasts 3 months, give or take. I value container plantings, as they celebrate the season at hand, so I’ll take three months.

Everything in the garden is ephemeral to one degree or another. A white oak tree can survive 300 years, and the lilac bloom time in my zone is 2 weeks in a good year.  The crocus can be felled by frost the first day they open, or with cool days and nights, last a few weeks. The transitory nature of life is part of what makes it so precious. The Rosebud cabbages in the above picture were grown from seed, probably sown in late June or July. Three or four months past the germination of that seed, they look as luscious as they are robust. I expect this pot will look good throughout the fall, and into early winter.

Broom corn is a crop grown for just that reason-corn brooms. The seed is a favorite of birds.  We have to keep the garage door at the shop closed, otherwise we would be inundated by birds. But this material has interest even when the seeds are gone. The long stringy stems would persist all winter and then some. We use all sorts of materials in concert with the cabbage and kale-some natural and some not. The big idea is to represent the fall season in a satisfying way.

The Finish

All that work early last week in preparation for the installation of a group of pots planted for fall came to the following. I hope you enjoy them.

Our fall container season will pick up steam from this point on, as will the fall landscape and garden. Looking forward to it.

The Prep

As busy as we have been with landscape installation projects, we have a full roster of clients for whom we do fall container installations. We are happy to oblige. I understand wanting to change the pots out for the season to come. A summer planting that has declined, or not done well, or which has not measured up to expectation – it can be a relief to put that planting to rest, and move on. I have other clients who would prefer to move on to the fall when the summer planting is at its super nova best. Watching a container that has been a pleasure to experience the entire season go in to decline is a painful acknowledgement that the garden season has begun its long slide towards dormancy. Yet other clients like the fall season the best, and are ready for a new look as soon as the night temperatures drop. Not matter the reason, we are available to plant containers for fall. We try to treat the fall season with fresh eyes, and we like to represent the fall season in the most robust way possible. The summer season provides no end of plant material that is tall and vining, of medium height, of short stature, and of trailing habit.  I could make lists. But the fall season challenges anyone who plants a container to create a variety of levels, contrast, and volume. We look first at the construction of a centerpiece that might organize the entire arrangement. Our fall container pots sometimes feature centerpieces of a variety of materials that celebrate the end of summer, and the harvest. Constructing those centerpieces is in preparation for a fall container planting.

We rely in great measure on the height, volume, and color provided by cut stems of broom corn. The seed heads and drying leaves can provide a dramatic centerpiece to a fall pot. The broom corn we purchase is hung upside down from the moment we get it. That drying process up side down will challenge the effect of gravity – somewhat. This fall maturing crop was and still is grown for the production of corn brooms, but we value its bold good looks. Marzela has a gift for handling and arranging these heavy stems in a graceful way. Her centerpieces, no matter the materials, anchor the plantings we are about to do.  All of her materials are arranged around a stout bamboo pole, the length of which will be driven in to the soil in the pot. She has been creating centerpieces our installation scheduled for tomorrow, for the past 2 days.

Some summer pots have centerpieces that still look great.  I am thinking about the figs, the lemon cypress, the rosemary, the boxwood topiaries, and a whole host of dwarf evergreens. But other central players in summer pots will go down in concert with falling night temperatures. There are few fall plants that provide stature, and represent the color or the spirit of the season. So what other materials might be available? This is the long way of saying that not every centerpiece we do for a fall pot involves live material. In the interest of celebrating the fall season, we may assemble lots of materials that are not especially living, but are very lively visually. These centerpieces are a mix of all of the above. The bleached kuwa branches are a natural curly stem available to us in dried bunches. The preserved eucalyptus is a natural material that has been treated to last for months, no matter the weather. The white berry picks are as fake as fake can be. But they reference the natural world in a graphic way.

These centerpieces are slated for a specific pair of pots on a terrace that features a number of pots. The primary view is from a distance, so the creamy white centerpiece will read.

This centerpiece will be viewed from up close, so the darker colors and more subtle variations in color will be appreciated. A centerpiece of distinction, no matter the origin of the materials, can endow a fall container planting with with fall appropriate style and verve. I like the idea of endowing the garden with seasonal plantings that are vervacious. If you are a gardener like me, you understand that a garden and landscape is about a certain kind of earthy and unforgettable romance. I am a fan of bringing on the romance every season. The fall season coming up asks for a representation of the end of summer harvest.

Of course every fall pot we plant involves living plants. All of our custom grown cabbages and kale are incredibly well grown. See for your self. They benefit from regular water and food, as they are growing fast this time of year. Our September weather has been unseasonably warm,. Once the temperatures cool, the leaves will color up dramatically, in shades of purple, pink, cerise, and white. Tuscan kale is a tall, all green variety that I hear is delicious to eat after a few frosts. Having superior quality plant material available to plant makes the process and outcome a pleasure all around.

The outer leaves of this cabbage variety, Osaka Red, will darken, and the center will turn a brilliant deep cerise pink, given some chilly weather. The look of the pots will evolve as the plants take on their fall color. If the early winter season is mild, these glorious and showy ornamental vegetables will look great in to December.

Each centerpiece has a photo tucked into it that shows which pot it belongs to, and what will be planted with it. That kind of planning helps to make a large planting job go smoothly and efficiently. But no matter the planning, seeing the work come together is always a pleasure. Pictured above is a trio of pots planted for fall last October. This year’s pots will feel just as fallish, but will feature whatever interesting materials Rob has purchased for the shop.

The Ruby Queen cabbage, the kale “Pinstripe”,  and broom corn are all looking good.
