Too Hot

elegant feather plantA very long run of blisteringly hot days is tough to cope with in mid June. No person or plant is ready for July weather this early. The elegant feather plant, a native of Texas, is wilting in this container. We have lots of seasonal and annual plants in small containers at Detroit Garden Works. Windy weather in the 90’s means those pots on the first bench dry out before the last bench gets watered. Rob and Amanda have been on the business end of the hoses non stop for days. When I turned 60, I told Rob I did not want to water any more. But I watered today. Patty Watkins, co-owner and waterer in chief at Bogie Lake Greenhouse, is ready to turn over her hose to her daughter Jessie. Patty is just about the kindest, most friendly, most helpful, and most even tempered person on the planet.  If you shop at Bogie Lake, you know this. But the heat in her greenhouses is taking its toll. She is really ready to drop that hose. I can’t imagine how she and Mark have been coping.

late June container garden (14)I had a landscape call this morning with a client. The three of us met at a table in the back yard at 10:30 am. The sun was scorching. It was a relief to all of us when the plan review was done. Sitting in the sun when it is 93 degrees is unpleasant to say the least. In the car on the way home, the air conditioning blasting, I was thinking about the sun. The light of the sun reaches earth via radiation. That light is translated into heat. I am hazy on the science, but I do know a shady spot out of the sun makes heat much more tolerable.

late June container garden (15)It is astonishing that the sun, some 93 million miles from earth, can send any gardener running for cover. How heat affects people is well known. Last week’s container plantings and landscape work made for a busy week. Hot weather we take precautions. We may start work early, and quit before 3pm. Or we schedule the hot spots in the morning, and the shadier work in the afternoon.

late June container garden (10) When the weather is incredibly hot, it is important to understand how that heat affects plants. Tropical and seasonal plants originate in climates known for very hot weather. My containers at home were planted only a week ago.  I know they have not rooted into the surrounding soil yet. Though tropical and seasonal plants have an incredible capacity to thrive in high heat, that capacity implies a root system that is well established. The short story?  I am watering every day.

late June container garden (16) The container in the foreground featuring zinnias, petunias and variegated licorice will be happy with a hot and dry summer, once the plants are established. Other heat loving plants include mandevillea, ageratum, trailing verbena and lantana. Lavender and rosemary, and other plants with needle like foliage are uniquely positioned to tolerate heat. Their leaves have very little surface area exposed to the desiccating effects of heat and wind. My butterburrs, on the other hand, with their giant thin leaves, will wilt at the first sign of high heat. Dahlias will react similarly. I did replant isotoma around the fountain. A tuneup to the irrigation means I will be able to give them the water they need. The Princeton Gold maples provide them with a little afternoon shade.

late June container garden (12)I planted my containers at home based on a prediction by the National Weather Service for a summer season that would be very hot and dry. And a request from Buck for “big leaves”. I have never been much of a fan of alocasias myself, the byproduct of which is that I have never grown them. It will be interesting to see how they do.  I did locate them in areas where they have bright light, and not so much sun.

late June container garden (13)This container always has lime nicotiana.  Both the attending New Guinea impatiens and begonias will be fussy in the heat. I always water rot prone plants at the soil line, and avoid getting the leaves wet. I only water when they are dry, and not when the air temperature is high. I do not give my plants a cool shower. Though I may find that a good idea on a hot day, what I like is not necessarily what my plants like. They need moisture in the soil to thrive. Moisture in the air is another word for humidity.  Humidity can foster mildew and other fungal problems.

late June container garden (5)No seasonal plant thrives in great heat more than caladiums. This dwarf pink variety with a green edge is beautiful.  The maiden hair fern you see is not a hardy variety.  It is a tropical variety which will handle our heat, given sufficient water. I do recall a summer in the 1980’s with incredibly high temperatures and little rain. A nursery we dealt with in Lake County in Ohio lost thousands of rhododendron and Japanese maples.  The soil temperature was so high that the plants perished.

late June container garden (4)I know that fuchsia thrives in cooler conditions.  I have tucked this fuchsia Ballerina standard close to the north wall, hoping that a lack of sun will keep it sufficiently cool. I have had good luck in the past growing this cultivar throughout the summer. Plants that experience higher temperatures than what they can tolerate will aestivate, or enter a mild state of dormancy as a survival mechanism.  This means they will quit flowering until the heat passes.

late June container garden (19)My  driveway garden is sunny for a number of hours, and shady for better than a number of hours. It is a good spot for New Guinea impatiens. No seasonal plant protests dry conditions more dramatically than New Guinea impatiens. They can wilt down an hour after they have gone dry, making the foliage look like braised lettuce. I try never to let them get this dry. The stress extreme stress from lack of water is so hard on plants.

late June container garden (22)The good part of the heat is that plants that have barely been in the ground a week are taking hold and beginning to grow.

The John Davis Roses

climbing roses (11)One of the many benefits of planting summer containers for a client that has had a landscape and garden designed and installed by us is the chance to see how that landscape is growing on. This client is 45 minutes away, so my visits are not all that often. I will drive out whenever there is a problem that needs some attention. But this yearly visit is never about trouble. It is about adding some seasonal plants to a garden that is the apple of its owner’s eye. She not only looks after it, she truly enjoys every bit of it. Planting her containers in June is a pleasure. The soil is warm, and the plants that have spent the early weeks of the summer protected from unpredictable weather in a greenhouse look great, and will handle the transplanting without issue. Though we planted 21 containers today, the big news of the day were the John Davis roses.

June 13, 2016 055John Davis is one of the Canadian Explorer Series of extremely hardy and disease resistant roses developed by Agriculture Canada in the 1960’s.  The goal was to hybridize garden roses that would not only withstand cold northern winters, but would perform beautifully in spite of it. John Davis is hardy in zone 3-think of that. There are quite a few roses in the series, all of which are good garden plants in my zone, meaning they are tough plants that shrug off the fungal diseases roses are famous for. They bloom as if there were no tomorrow. John Davis is a great choice for a not too tall climber that has the look of an old fashioned rose more often seen in England or California.

climbing roses (6)This is the 4th June for the John Davis climbing roses planted on each post of a pair of long pergolas that frame the view from the back of the house to the lake. Each was planted with a companion clematis, which range in color from white to dark purple. The clematis do not seem to mind the competition from these vigorous roses. Though John Davis usually tops out at about 7 feet, these roses are up 9.5 feet off the ground, and have started to grow over the roof of the pergola. I will be interested to see if they keep adding more height. I have planted John Davis in a number of gardens, almost all with great success.  This group has seemed happy from the moment they were planted.  The soil is heavy clay, and does not give its moisture up easily.  There is a constant breeze from the lake, which I suspect has something to do with the fact that I never see mildew or black spot on the plants. They get a yearly dose of rose tone, and extra water when they need it. All that remains is to stand back in June, and take in the bloom.

June 13, 2016 065The lax canes have had some support to attach them to the pergola poles, but that is not visible. The flowers are not particularly large, but there are thousands of them on each one of these plants. I am surprised that this series of roses is not more readily available in my area.   The roses we have available at Detroit Garden Works, including John Davis, had to be custom grown. I made arrangements for that almost a year ago.

June 13, 2016 047I understand the reluctance to grow roses.  They are ungainly plants that no one would have, but for the bloom and perfume.  They routinely fail.  I mitigate that tendency by planting the graft 2 to 3 inches below ground. No gardener wants diseased plants in their garden. Choosing roses with a clear track record of resistance to disease and hardiness is educated buying. The Canadian Explorer roses might be worth a look. I find that they are reliable in every regard.

June 13, 2016 110Roses in bloom like this is a garden experience like no other for a gardener who greatly values romance. Roses invoke romance like no other garden plant. I would go on to say that the big idea here is that any garden plant in the right place and endowed with the proper care will thrive. So much about the success of a garden depends on a thorough understanding of the horticultural requirements. I am rarely perfect in this regard. I have been known to short some greatly needed sun to sun loving perennials. I have placed my share of part sun perennials in shade that is too deep. I have exposed shade plants to blistering sun, in the hopes they will adjust.  I have planted perennials that require perfect drainage in soggy soil, in hopes I could skate by.  Suffice it to say that everything I have leaned about planting perennials has come from the plants.  Any plant that is unhappy will speak back to me, if I am inclined to observe, and listen.

June 13, 2016 080These John Davis roses in bloom are extraordinary. I can only claim that I somehow managed to put the right plant in the right place, in the beginning. What had happened over the past 4 years is a constellation of events attended by nature, and looked after by an extraordinary client. This does not happen so often. Thanks, Harriet.

Early June

June (10)As much as I treasure the spring season, early June is a garden moment like no other.  Every tree and shrub is in full leaf, and growing apace. Just about every perennial is not only growing, they are making plans to bloom. Even my hardy hibiscus show signs of stirring. The garden is action packed. The Princeton Gold maples against a a stormy sky last night-spectacular. Those trees dominate my landscape in June, as you can see. One would never know there are houses just past those trees.  Just this year, the last of the electrical pole in the corner that services 3 other houses besides mine and its overhead wires have disappeared from view.

June (5)My landscape is not one bit fancy, although it is grown up. It is an urban American garden to my liking on a very small parcel of land. It is simple in design, so if it gets neglected when I am busy, order can be restored in a day or two. I like the orderly part of my landscape, as I find that order relaxing. The best part of coming home at the end of a busy day is having nothing to do in the garden.

June (8)What I will plant around the fountain this year is the subject of much internal debate. I can only ask Buck to talk to me about it so many times, and I have already gone over the limit. What is that plant that will like the sun at one end, and tolerate the shade at the other?  It has to suffer the indignity of the dogs wading through it. And the over spray from the fountain jets on a windy day. I solved one chronic problem this spring. I had the irrigation system enlarged to include this area. No more dragging the hose down there from the deck on a 90 degree August day. I tried isotoma fluvialitis, but it was not hardy for me.  I did get 3 years from both herniaria, and scotch moss.

the beginning of June (8)I have yet to do one thing in this garden, and it doesn’t show – but for the dirt around the fountain. The month of June is the busiest of my year. This year is exceptionally busy. Several landscape projects are in process, in addition to the summer plantings. The fact that all I have to do when I get home is look around is a relief.

the beginning of June (10)I have not planted my pots yet, but I have plenty enough going on to keep my eyes occupied. I will try to have them planted by June 15.  Annual and tropical plants going into soil that is thoroughly warmed up will take hold and grow with little in the way of transplant shock. To follow are more pictures of my early June garden, without much commentary. I need to go attend to someone else’s garden right now.

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. Interested in the article? http://www.floretflowers.com/2014/03/flower-focus-growing-great-zinnias/

 

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.
