Some Like It Hot And Dry

 

Screen Shot 2016-03-01 at 6.11.57 PM_zpsv6bhufehChoosing plants for summer containers can be complicated, especially if you are as serious about them as I am. I have to be serious, as I plant them professionally for a wide range of clients. But lacking any clients, I would still be serious about them.  They are seasonal expressions of the landscape confined by a finite world known as a container. The idea of this enchants me. A great container planting is a condensed expression of color, mass, line, texture, mass, shape and mood. Like the best chocolate mousse you ever ate. The thoughtful landscape and garden builds and endures and reinvents itself from year to year. Like a great stew. Seasonal containers provide an opportunity to express an idea or point of view that needs no more commitment than one season. If this year’s annual containers do not satisfy, the next summer season is not so far away. Landscape design and installation can be a lengthy affair.  The road to maturity is long, and not always easy.  The death of a tree is momentous; a petunia lost is no cause for alarm.  That container plantings last for one season is such a blessing. As much as I embrace the tough and long road designing and implementing a landscape, I value those gestures that are quick and true. I design containers by instinct. Every season, a plant that interests me, or a group of plants that seem like they will create a neighborhood gets my attention.  But long before I shop, I scout the long range weather forecast for my zone.

Floret FarmsA forecast for much above average temperatures, and dry conditions means I started paying special attention to those seasonal plants that will thrive in those conditions months ago. I have always been a fan of those old fashioned cutting flowers-the zinnias.  If we have a rainy or very humid summer, they are a magnet for mildew and all manner of fungal disease. Reading the forecast in March, I started researching zinnias. A dry hot summer would be the perfect moment to plant lots of them in front of the shop. I was especially interested in unusual forms, vigor, resistance to disease, and and that old fashioned charm they are known for. In reading about zinnias, I came across a blog post from Floret Farms.  They grow armload after armload of the most beautiful cut flowers I have ever seen-just like the cut zinnias you see in their picture above.  I did take some of their recommendations to heart.

DSC_6426Zinnia Queen red lime has very unusual and muted coloration-unlike many of the varieties that feature intense color.

DSC_6433It’s sister cultivar, Queen Lime, is a much improved version of the old lime green zinnia “Envy”.

Zinnia elegans 'Queen Lime' (2013)Benary Lime tends towards the greener side of lime. From the Johnny’s Selected seeds website:  A classic and superior strain of zinnia originating from a historic German seed company, the Benary’s Giant Series features large, double blossoms of approximately 4–5″ in diameter, in multiple magnificent colors. Recommended by the Association of Specialty Cut Flower Growers for their vigor, uniformity, productivity, and carefree cultivation across a range of growing zones and conditions.  From Swallowtail Garden Seeds: The 3-4 inch, double chartreuse flowers are superb for cutting, blend with almost any color. Outstanding massed in the landscape; the flowers are jaw-dropping in mixed bouquets. Plants are rain, heat, and mildew resistant. Somewhat shorter than others in this series, growing 24-26 inches tall.

DSC_6423I first read about this zinnia at Floret Farms.  Uproar Rose is a hot pink zinnia that is reputed to produce flower heads at 5″-6″ across all summer.  It makes an excellent cut flower, and is resistant to fungal diseases. Floret favors this zinnia, as it has lots of side branching – meaning it will bear lots of flowers.  I added this zinnia to my collection.

DSC_6435The Zinderella series, in both peach and lilac represent a very unusual anemone type form. I see not every flower on the stalk is quite as double as the ones in my pictures, but that is not enough to discourage me from growing them. They grow about 24 inches tall.  I mixed all of the sizes and colors of zinnias for a loose look, and I have twice as many lime zinnias as all of the other colors. That lime will make it so much easier to appreciate the color and shape of the other varieties.

DSC_6434Zinderella Lilac

zinnia Polar BearA little splash of white is the perfect accent for a garden with lots of bright color. This is the tallest of my zinnias, topping out at 40″. Polar Bear white is an appropriate name.  It cools off the collection.

Canary Bird Zinnia Zinnia Canary Bird rounded out the tall zinnia group.

51985-pk-p1I did not want to neglect the shorter and more compact zinnias.  I did opt to grow the Zahara series.  From Park Seed:  The Zahara series introduced in 2009 immediately became famous for its resistance to mildew and leaf spot, its nonstop blooms, and its larger flower size.These blooms are fully 2½ inches wide. Renowned for its ability to withstand heat, humidity, drought, and just about anything else, Zahara is the first bedding Zinnia that can truly claim to be disease-resistant. Mildew is a traditional enemy of the Zinnia, but Zahara’s got it licked!

F_Zinnia_ZaharaStarlightRose Zahara Starlight White is especially beautiful.

DSC_6431The wicker pots out front are planted with elegant feather, tall yellow marigolds, marguerite daisies, pink petunias and lime licorice.  We dug around the stone plinth, and planted Zahara zinnias.

The First Container Planting

annual planting (3)
Every year, the prospect of having a full roster of container gardens to plant makes me want to black out. I spend the first three weeks of May utterly certain that I cannot plant one more pot.  That I am out of ideas. Luckily, time passes by, and and I start shopping. A client I have worked for as long as this one is easy to shop for. I had a pair of giant banana plants to pick up at our farmer’s market at 5:45 am. I was ready at 7am to let Dan know that we would need two pallets-130 bags –  of our custom container soil blend, and 30 bags of bark. We would need moss fabric for a pair of wire urns, and a ladder to tie the mandevillea to the steel plant climbers.

annual planting (12)I had shopped with David and Riley on Friday.  They put all of our plants on racks, and loaded them onto our trucks.  At the end of the day Friday, I was ready in the plant regard.  I had an inkling of an idea about what I would plant. Of course I was going over that inkling, critically. I had from 6-8am Saturday morning to print the photographs from last year, and write on them what materials we would use in them this year. Two hours gives me enough time to change my mind. Once my crew is ready to load, I am too.  I take extras and alternates, just in case.

annual planting (5) Once every pot had gotten filled with bark for drainage, and our container soil mix, all of the centerpieces get planted.  Then I lay out the scheme for the rest of the pot.  I was entirely absorbed and focused on how each plant would grow out, and interact with its neighbor. I favor containers that have a beautiful overall shape by the time they mature.  My favorite part of this planting for a group of Italian terra cotta pots? Orange geraniums. Geraniums, as they provide an incredible amount of color when properly grown.  They are heavy feeders. But more so than the bloom habit, that orange would contribute an interesting variation to a warm color palette.  The red mandevilleas and red geraniums are a bluish red. The orange geraniums have just enough yellow to make the combination interesting. My client is keen about the drama that can be created by intense color.
annual planting (6)This pair of Italian pots can handle the size and textural drama of a pair of large scale bananas. Not yet visible are a collar of strobilantes, or Persian shield plants that will ring the trunks of the bananas.  The chartreuse leaved Persian Queen geraniums and misty lilac waves petunias will highlight the iridescent red-violet of the Persian Shields.

annual planting (9)Lime green is a key color in this planting scheme. All of the warm colors are all the more intense, by their proximity to lime green. The red represented in this container is red sunpatiens. They will grow quite large.  The lime licorice will lighten that load of red.

annual planting (7)This big scented geranium will have pale pink flowers intermittently over the summer.  But they are primarily grown for their bright apple green foliage that can be clipped into shapes.  We gave this geranium the most rudimentary clip.  My client has a lot of formally trimmed shrubs maintained by the company that prunes our boxwood at the shop.  Her crew will put a skilled set of hands to the spherical shape of this geranium.  It is under planted with an orange geranium of a different sort than the big growing zonal geraniums.  Caliente geraniums come in a wide range of colors, and are extremely easy to grow. The pink and white bicolor trailing verbena “Lanai Twister Pink” is a beautiful addition to this series.

annual planting (11)There are two containers in fairly dense shade.  The color of the lime dracaena “Janet Craig” brightens any shady area.  The dracaena is under planted with bird’s nest ferns.  The leaf form is simialr to the dracaena, but is a darker green.

annual planting (8)A boxwood topiary on standard is under planted with Persian Queen geraniums, red geraniums, and vista fuchsia petunias. The low terra cotta bowl features hot pink XL dahlias, black cherry supertunias, and a bicolor trailing verbena.

annual planting (10)3 terracotta boxes get identical treatment.  Hot pink zonal geranium towers, and lime creeping jenny.

annual planting (14)This old cast iron rectangular cauldron sits in a garden bed which is so shady that very little grows there. It is planted with a a pair of lime green fleck leafed dieffenbachia “Camouflage”, Janet Craig dracaenas, and Black Gold Xtreme sansevieria. The sansevieria in the box is repeated in ground at each end. This planting will thrive all summer long with next to no water.

annual planting (1)By 2pm, you would never know we had been there. It was a splashy beginning to our container planting season.

persian queen geranium and lobeliaMy recommendation for containers this 17th of May in Michigan?  Do not be thinking coleus, New Guinea impatiens, begonias, licorice in any of its forms, sweet potato vine, cannas – the list of summer container tropical that do not tolerate cold soil is long. Annual plants that are greenhouse grown for summer containers will not like our cold soil, or the cold air.  Refrain from planting these cold sensitive plants until the soil and the air temperatures warm up. Containers planted with spring and cold tolerant plants deliver every bit of three months, and will happily accompany your spring garden coming on. Choose to be in real time. The choices are many.

spring container in mid MayThe tropical annuals that are greenhouse grown for summer containers are living in a warm world right now. Everything regarding their culture is right as rain.  They have great soil. They have been fertilized. They are growing in a warm environment. Their place on a greenhouse bench is an ideal world. A greenhouse, on a sunny day in March, gets very warm, as in upwards of 80 degrees.  Those sunny days in April push those plants with tropical origins into very active growth.  A greenhouse crop of container plants is usually available for purchase way ahead of predictably warm weather outdoors. The transition from a hot house to your garden can be a huge shock to those plants. If you do not have a glass house to protect annual topical plants from the late spring Michigan weather, focus on what the spring has to offer.

viola potI understand the idea to shop now. Every serious gardener wants to purchase the best from a big collection. I would only suggest that your awesome early picks need to be, at the very least, housed in the garage until the night temperatures are reliably over 50 degrees. It can be heartbreaking, getting ahead of the weather.  At this moment, I am trying to stay focused on all thing spring.

Planting Container Gardens for Spring

spring container gardensYesterday morning dawned very windy, very rainy, and very cold. This is entirely normal for Michigan in mid-May.  What gardener is surprised by this?  All of us. Once Mother’s Day comes and goes, all of us expect that the time to plant summer containers is nigh.  Nothing could be further from the reality.  Spring in Michigan lasts for 3 months-the same length as any other season. Detroit Garden Works does have plants available now – as in cold tolerant, road ready for a spring container, plants. Cold sensitive summer plants – those are best kept in the greenhouse where they are being grown until the night temperatures are reliably above 50 degrees. . We have planted lots of pots for the shop in the past month, but all of those plants are adaptable to chilly spring conditions.

May 6, 2015 025We had lots of people come in yesterday, in spite of the pouring rain and cold. Our Amanda spent half the day scheming with Rob about how to protect our plants from the predicted overnight low of 32 degrees.  Gardeners of every persuasion, dressed in fleeces, rain jackets, sweaters, knee high rain boots and warm hats were asking in one way or another about when to plant for summer. I gave the same answer that I always give.  not now; not yet.

spring container gardensIt is fine to plant containers for spring now. It has been fine since late March. A late March planted container will thrive until the beginning of July. March, April and May are spring months in Michigan. Only cold tolerant plants thrive in containers during the spring season. Our  summer season opens in June, and goes through August. Would that I could convince more northern zone gardeners to celebrate the spring with lots of spring flowering bulbs and cold tolerant container plants. We hold a spring fair every year, with exactly that purpose in mind. There is so much about the spring season to enjoy. Experiencing the process of the landscape and garden waking up in spring is an extraordinarily beautiful phase.

DSC_5433 We planted lots of containers with daffodils this past fall.  From the moment the leaves broke ground until the blooms began to open was over 6 weeks ago. Watching those bulbs break dormancy  is an experience of the spring season that is not to be missed. A container planted with spring flowering bulbs provides a visual short course in how the seasons change from winter to spring. Some foliage that emerged early was damaged during a run of very cold nights in late March. The flower buds were unharmed, as they came later. Our cold persisted throughout April, and now in to May. Those normal chilly temperatures are a luxury. All the spring flowers going into nature’s cooler at night means they are available to enjoy over the longest possible period of time.

potted daffodilsYou may think the spring arrives overnight, and vanishes within a few days. This is not the case. The trouble and expense of planting containers for spring will be rewarded with a whole season’s worth of pleasure.  We do not force our daffodils.  We pot them up, and winter them in our unheated garage.  As soon as the temperatures warm a bit in March, we move them outside.  The fact that the bulbs are not forced into bloom outside of their normal season means they can be planted out in the garden, where they will bloom at the normal time next year.

potted daffodils It is not a good idea to plant for summer just yet. There are so many good options for spring one hardly knows where to begin.  In the garden, the hellebores and spring flowering bulbs have been in bloom for weeks.  The scilla hyacinthoides and camassia are coming on.  The sweet woodruff, and loads of spring wildflowers are in bloom. The Virginia bluebells are particularly good this year. The magnolias are still holding on, and the crabapples are still coming on. The American dogwoods are in full bloom. My clematis have been growing steadily, and are budding up.  A dense patch of ornithogalum is in bloom. The fern fronds are uncurling, and the hostas spikes roll out new leaves every day.  The fresh leaves on the Princeton Gold maples are the most intense shade of chartreuse imaginable. So much spring around us!  There is something new to see every day.  These are not the dog days of summer. These are the emerging days. Some containers to compliment the spring season-a natural.

Mother's Day flowers (7)Is it fine to plant containers for summer right now?  No, it is not. Spring is not the time to plant for summer. Summer annuals look out of place now, as they are not yet in season. Nor will they do well. Tropical plants set out into cold soil and air temperatures may be set back for for a long time from cold shock. Your local greenhouse can easily reach 80 degrees on better on a sunny day. Plants that thrive at 80 degrees do not want to be outside now.  If you made no plans to plant a few containers for spring, it is not too late. What you plant today will be great looking into July.
