Vegetables to the Rescue

My well thought-out flower garden, especially the part I see from my bedroom window, is a sad sight.  I had pinned my hopes on veronica speedwell 'eveline', a deep pink veronica, carrying on all summer long.  It will bloom again, in a week or two.  Now there are few blooms and little color.

The lawn is even sadder - full of dead and dried out spots.  My less than perfect lawn prep of 25 years ago always haunts me in mid-summer.  The lawn is uneven.  When mowed, the high parts are shaved rather than cut - leading to burned-out patches.

I always find redemption in my husband's vegetable garden.  Despite frequent, heavy rains that knocked the young fruit off the tomato plants early in the season, it looks like we will have a good crop.  My husband followed a neighbor's lead, and added several loads of compost, free at our town dump, to the vegetable patch.  Even though the tomatoes have not ripened, there are lots of them, and they look healthy.

We have been harvesting green beans, zucchini, and cucumbers. Butternut squash, a surprise plant, will be ready to be picked soon.

The squash blossoms are lovely to look at.  Some day I will try cooking them.  The zucchini will be ready in a day or two.

Worth the Bother

The middle of summer is a good time to talk about plants that are worth the bother, and those that aren't.  The red lily leaf beetle, a non-native, infests true lilies (not day lilies) in the US Northeast to such a degree that experts recommend not putting them in your garden.  The beetle eats all of the leaves, thus robbing the plant of its food source - chlorophyll.   Perhaps twenty years ago, before the arrival of the beetle, I planted several varieties of lilies.  Unfortunately, I do not remember their names.  Some of them have done well, although not as well as they used to.  My husband sprays them with pesticide in the spring. I believe that parasitic wasps, one of their only predators, have been imported from Europe, and may be controlling them naturally.

As you can see, the lilies that have survived are lovely.  They are one of my favorite plants.

A plant that I will probably get rid of in parts of my garden is phlox paniculata, or garden phlox.  The plant has a lot going for it - beautiful white, pink or magenta flowers in mid to late summer with a lovely fragrance.  What it has against it is mildew.  I have some phlox growing now that are mildew free and blooming profusely.  Others, despite careful pruning early in the summer, are full of mildew and have not started blooming yet.  I may change my mind if I get a good bloom, though.

One last note for this week.  I just dropped my oldest daughter off in Fargo, North Dakota for graduate school.  I noticed that there were no azaleas or rhododendrons - clearly the winters are too long and harsh for them to survive.  White hydrangeas were plentiful, thought, and a deep red shrub that I did not recognize.  I would have expected more prairie grasses, but saw few gardens with them.  

Wallpaper

I haven't posted in a few weeks because of the incredible heat in Boston, which made it impossible to work on my computer (3rd floor study), and because of a trip to Washington, DC to help my daughter pack up her apartment.  I am also not ready to give an overview of the season.

I titled this post "Wallpaper" because that is what one section of my border looked like - safe, coordinated, boring.

The plants in front are a violet-pink veronica (one of my favorite plants - well-behaved, easy to weed around, long-blooming, and good color choices).  The chartreuse flowers behind the veronica is Lady's mantle.  Even though shorter than the veronica, it is in the back because it is not well-behaved; it spreads.   

I added begonias with white flowers and burgundy foliage in front of the veronica.  I chopped back the Lady's mantle a bit (more will be done later).  Finally, I added two delphinium 'Black Knight" Pacific Giant.

Even though the begonias have not done much yet, they add enough of a contrast to this section of the border so that it no longer looks like wallpaper.  I hope that they grow a bit more prominent.

  
Lavender to the right and phlox to the left are getting ready to bloom.  I will give an update after my next trip - this one to Fargo, North Dakota, to help my daughter move there for graduate school.

More Color

Color hue is important in designing a garden.  So is the intensity of the hue.  Early this spring I placed three yarrow plants (achillea yarrow), in a section of border that is dominated by pastel shades.  I thought their yellow  flowers and silvery foliage, would look nice against the phlox and its white flowers.  The yarrow bloomed beautifully, and was very bright yellow - too bright for the spot.

The intense yellow dominated the space; my eye kept jumping to the yarrow, and was not moving around the border. 

I moved the yarrow to a section of border that has vibrant colors. 

 

The yarrow looks much better in its new spot, next to the brilliant orange flowers of  asclepias tuberosa (butterfly weed).

Next time, an evaluation of the season.

Color, Round 1

There are volumes written, and yet to be written, about color in the garden.  I will write about what I think is the most useful.

First, a few definitions.  Hue, is what a color is at its most basic:  red is a hue; pink is a tint of the hue red (a hue which has had white added to it.)  Burgundy is a shade of the hue red (a hue which has had black added to it.)

Below is a 12 hue color wheel - the one that I find the most helpful in my garden design.

Notice the way the colors are arranged.  Each color is opposite - or 180 degrees away from - its complement, or color which does not contain any of its opposite.  For instance, yellow is opposite violet.  There is no yellow in violet - violet is a combination of red and blue.

Complements are important in all color design, for they give the design balance, which the eye is always looking for.  An unsettling situation occurs when hues are used that are almost complements, for example, yellow-orange and violet.  This combination can (doesn't always) create simultaneous contrast.  In this case, the eye keeps hunting for balance which is almost there, but not quite.  Simultaneous contrast can most easily be seen in Op Art, where the image created can appear to be moving.  This phenomenon does not usually happen in the garden because there is so much green around.  The way to defuse simultaneous contrast is to add another color.

You can also use colors that are neither complements nor near complements.  Such a scheme might include red, yellow, and blue.  This combination would be boring if you were just to use these three hues, as you might in a graphic design.  This combination is less boring in a garden because of the presence of so much green.  The green actually helps tie the colors together because green contains yellow and blue, and is the complement of red.

Next time, I will write about intensity of color.

The Cone of Vision

The cone of vision is a concept I learned about in an illustration class.  Understanding it helps the artist create realistic scenes because it captures approximately what your eye can see without moving your head.  (Imagine drawing  a fifteen degree line from your eye to both the right and left of your eye - that is about what your cone of vision will be.) You can use it to design gardens that are unified and pleasing.

If you have a garden that is open to the street and not obscured by trees, buildings, and hills,and if the garden is first seen from far away, the cone of vision is large.  That is, more can be seen even though the angle does not change. A garden seen from far away should have a unified theme, feeling, or color scheme.  This garden will probably also be seen at an intermediate and close distance.  Use variety in color, foliage, and bloom time to make the garden interesting from these distances as well.

People who plan municipal gardens along streets use the cone of vision to design gardens that will make a big impact when people drive by in cars.  Most people are going to get a very quick view of the garden, and usually from specific angles.  A garden might first be viewed as a curve is rounded - perhaps shrubs will be placed so as not to be parallel to the street - but at an angle to it - giving the best view. The municipal gardener does not need to invest in a big assortment of plants - just the opposite.  Too much variety will confuse the viewer's eye and create an unpleasant experience.

Small gardens, such as those found in urban townhomes have a limited cone of vision.  Here, variety is important.  Too much of the same plant is boring and depressing.  Different  foliage types, plant shapes (tall, rounded, pendulous,,,), foliage color, and bloom time should be used.  Just make sure that you help the eye move through and around the garden.

A third type is where the garden is seen  up-close and  intermediate distances.  I have included pictures  from one of my borders to help illustrate how I have used cone of vision.

The first picture shows part of the garden as you approach it.  A rhododendron obscures the rest of the border.

 
This view includes some pretty irises - but you have to keep moving to see more.  This area is a tease. It should encourage people to look for more garden.

This next picture shows what you see as you proceed around the bend.

There is more to see, and it is quite pleasing.

As you continue to walk, you can look at one section of the garden from fairly close.

This part of the border has a pleasant color scheme and good foliage variety.  Notice the dwarf Alberta spruce to the left of the picture. It is an important design element, as can be seen in the next and final photo.

That same Alberta spruce can be seen in the distance now.  It helps break up the border into "rooms".  The first "room", all the way to the left, will soon have lots of hot colors - bright oranges, yellows, and yellow oranges.  The second "room", the one that you see in the above two photos, has a calmer, pastel palate.  The third "room", created by the placement of another Alberta spruce, is one with shade loving plants.  All three "rooms" have a different feel.  It would have looked funny to have "hot" colors next to pastels next to muted shade lovers.  Separating the areas with shrubs lets you look at the entire border and find it satisfying, rather than jarring.

Notan Revisited

I recently saw Matisse's painting The Green Pumpkin at the RISD Museum in Providence, Rhode Island.  I cannot show a picture of the painting; you can google it and see a picture (don't just google "green pumpkin", though.)  The painting is designed with definite bands of color that extend from one edge horizontally to the opposing edge.  Then there is the green pumpkin, close to the middle of the painting, flanked by blocks of the same green.  (Although there is no continuous band of green, the eye interprets the green objects as being in a green band.)  I realized that Matisse had used Notan in the design of this painting even though he did not use extremes of darks and lights.  By using Notan, he helped the viewer discover what was important in the painting, and keep the viewer's eye moving throughout the painting, and not flying off of it.

Color can be used the same way in a garden design as Matisse used it in The Green Pumpkin.   Plants are placed to help keep the viewer's eye moving throughout.

In the bed that I photographed from a roof deck, I have used plants with reddish-purplish foliage placed in the front left armeria maritima rubrifolia (red leafed sea thrift), middle center lysimachia ('firecracker' loosestrife), back right heuchera 'molly bush' (coral bells), and another heuchera to the front right.  My goal is to help people look at this garden so that their eye does not get stuck on one area, and does not wander off to some area outside the garden.  The red foliage plants help lead the eye around and through the garden.  All of the plants are seen because I have helped people make sense of the space.

Next time, I will write about cone of vision.
