Leaves Other Than Green

coleus.jpgLeaves other than the the color green can be cause for excitement. The vast majority of garden plants in my zone are green, as in garden variety green.  Not that I object to that.  Green leaves are not simply green.  They have size, mass, texture, contrast, surface, shape and form.  An all green scheme explores all of these design issues.  But leaves other than green are a magnet for the eye, and the gardener.  My knowledge of how certain leaves are other than green is very sketchy.  Some color seems like it is laid over green.  The leaves of this shocking pink and carmine coleus seem clear, and not at all muddied by a green layer underneath.  Wasabi coleus is a lime version of green.  Somewhere in the color mix of this leaf is lots of yellow.

gray-leaves.jpgSome gray leaves have a green base to them-as in this Silver Shield plectranthus.  Other gray leaves, as pictured above, show no hint of green.  Where am I going with this?  Color as a container, garden, or landscape design element is as personal as it is complicated.

dark-leaved-begonia.jpgI find that everyone sees color differently.  The perception of color is much about the science of vision, but it is equally about perception.  I like every color.  I respond to the absence of color, and the combination of all colors.  I respond to certain color combinations more strongly than others.  The orange flowers of this begonia, by contrast, bring the black green leaves to life.

red-bor-kale.jpgThe color of Red Bor kale is black, under laid by carmine pink. Dusky purple in color, if you will.  This dark gray purple asks for a companion that will play off of, or feature that color.  The yellow green scented geranium is a perfect companion.  Chocolate sweet potato vine would be an interesting combination.  A garden variety green leaf would be neither here nor there.

lettuce-bowl.jpgI have a very tough time designing with red foliage.  Red leaved Japanese maples are gorgeous on their own, but I do not see them integrated into a color whole successfully very often.  I find the landscape with blue spruce, red Japanese maples, and burning bush (a very dull medium green) jarring, and unsatisfying.  Blue in the landscape looks good far away from the eye.  Red in the landscape looks good up close.  Dull gray green-where does that color belong?

wild-lime-coleus.jpgThe coleus that are available now have strikingly beautiful other than green color.  Wild lime coleus permits the placement of the color yellow in the shade.  Sum and Substance hosta, and creeping jenny are lime green.  Wild Lime has a yellow center.  This plant has great color potential for a seasonal planting.

caladiums-and-polka-dot-plant.jpgSome leaves are not completely other than green.  They are mixed.  This mixed pink and green color caladium is good with the mixed color polka dot plant. How so?  The caladium has green in its leaf, as does the polka dot plant.  There is common ground.

coleus.jpgThis black edged pink/red coleus is a striking color.  I could see planting it with a companionable other than green leaf.  As in black oxalis. Or red alteranthera.

coleus-and-Boston-ivy.jpgLeaves other than green are not so color friendly to green leaves.  Do I like this combination? Not so much.  I like color relationships that provoke or relate.  Color relationships that are standoffish make me uneasy.

coleus-and-begonias.jpgThere are those green leaved plants that bloom so generously that their green leaves are not a color issue.  The begonia leaves in this pot are a secondary visual issue.  This container combination takes nothing for granted. The coleus in this pot is edged with green.  The green leaves of the begonia, and the green edges of the coleus are in partnership.  The orange flowers, and those leaves other than green make a partnership of another kind.  The terra cotta pot-there is another color adding to the whole.   A visual discussion of color in the garden-interesting.

 

Leaves Other Than Green

Just like you, I understand that the green color of leaves has everything to do with the presence of chlorophyll.  There are those dark green leaves.  There are those lime green leaves.  I want to say the amount of chlorophyll governs the appearance of that green, but I may be making that up.  Some plants have leaves with color other than green.  This Florida Sweetheart caladium-the leaves are shockingly pink.  A clear pink.  The color possibilities that this plant enables in a shady spot are many. 

white caladiums

I am both surprised and not surprised that I do not see more gardeners using them for seasonal color.  I do have clients that insist they want flowers, not colorful leaves.  I have no answer to that-it is a matter of taste.  But from a design perspective, caladiums provide an opportunity for a big splash of color that is constant throughout the summer season.  I suspect another reason why I do not see them much is that they require a lot of heat to grow well.  This means that gardeners in my zone who plant in mid or late May may not see caladiums available for sale.  My grower’s caladiums are just getting good-this third week of June.   

green and white caladiums
Caladiums are incredibly tolerant of shade.  If impatiens or wax begonias make you want to yawn, caladiums are refreshingly different, and quite splashy.  4 plants in one of my deck boxes last summer were the size of a small shrub by summer’s end.  A 4th of July trip to see a friend in Kalamazoo last year included a trip to a greenhouse.  I bought a suburban load of caladiums, most of which were varieties I had never seen.  I did persuade my grower to try some this year-they are just now coming into their own.
 white caladiums

Any client who tells me they need white flowers, as opposed to the color white might tempt me to call school into session.  White is white-no matter whether than color is represented by wax begonias, non stop begonias, angelonia, cosmos, cleome, dahlias, -or white leaved caladiums.  Amazingly, I saw 4 giant planters full of this all white caladium-in full sun, on a city plaza.  There was not so much as a single scorch mark.  I have not had the nerve to try this at home, as many plants lacking chlorophyll will burn if exposed to too much direct light.  

caladiums

I realize that almost all of the seasonal plants that are available for me to plant are tropical, as in native to tropical locales.  But some remind me of of their exotic origins more than others.  I have clients for whom I plant bananas, alocasias and calocasias, though I would not want them in my own garden.  They seem so blatantly out of place in my Michigan garden.  But caladiums are more subtly splashly, given their smaller mature size.   

caladiums

 They have a cool, watery, and juicy look.  As they thrive in the heat, they always look fresh.  If they get too dry, they protest dramatically by falling over.  I like plants that do not make a mystery of what it is they need to be happy.

pink and green caladiums

Caladium leaves are medium to large, and beautifully shaped.  It seems to me that so many more cultivars are available now than what used to be.  But should caladiums simply not appeal to you, there are other seasonal plants with colorful leaves from which to choose.

polka dot plant

The polka dot plants-there are those green and white cultivars.  There is a pale pink, and a hot pink.  The plants are fairly short-they may grow to 12 or 15 inches tall.  They respond well to pinching.

coleus Freckles

There are many varieties of coleus.  I am especially fond of those whose leaves feature bright and clear color.

green coleus

This subtly colored olive and dark carmine variety whose name I do not know is what I cal a chamaeleon plant.  Its coloration changes in appearance depending on its neighbor. 

coleus and caladiums

coleus chocolate mint

Coleus Chocolate mint is aptly named.  It is great looking with just about every other color.

multicolored coleus.jpg

This multi colored variety I hear tell wants full sun.  When I run into a plant that I am not familiar with, I like to try it at the shop or at home before I plant it for someone else. 

We’ll see how it works out-bullseye geraniums, and this fingerling coleus.

Dark And Dramatic

What makes dark leaved plants so irresistable?  Their relative rarity attracts the eye in an instant.  Of all of the thousands of green leaved plants in my garden, I have no plants with “other than green” leaves.  Were I to plant a red-leaved plant there, it would attract attention.  A red-leaved Japanese maple stands out from the crowd by virtue of its color alone-never mind that it is a tree with many virtues.  Red leaves can create excitement in a visually sleepy place; the color is unexpected.  Though I would not be inclined to indroduce red leaved plants into my landscape, I like them in containers.  These old red leaved spikes provide a dramatic accent to this grouping of pots.  The choice of lime licorice as an underplanting reflects my general rule-if I use dark leaved plants in a container, I stay away from green leaved companion plants.      

Once I make the decision to feature a plant with dark foliage, the supporting cast plants need be friendly to that color.  Lime licorice verges on yellow; inky fingers coleus has a deep purple ground, with just a hint of bright green on the edges.  Medium green and medium red make mud together.  I like sharp, crisp, delicate and dramtic color-no mud.  Big black foliage needs more black foliage to make a dramatic color statement.  The rim of bright green on this Inky Fingers coleus describes its small texture-it brings all of the color to life.  Medium green foliage in this container-thud.    

This red/black foliaged hibiscus is a very strong grower.  It can easily attain 6 feet in a single season.  The red and lime bicolor coleus and lime licorice light up that dark color from below.  I have thought on occasion to pair it with the big ruffly leaved farfugium; the contrast in texture would be great.  The red and green color combination I am reluctant to try.  Want an other than green foliaged scheme?  Follow through with every move you make.

I did make an exception in this case.  The strap leaved New Zealand flax, or phormium, is black leaved; perhaps there is a hint of brown.  The large, bright flower heads of the peach geraniums attract the eye; its great leaves fade away into the distance.  The violet petunias are so covered with blooms that the green foliage is scarcely visible.  This planting is dark and dramatic.

This large and black leaved canna is a boldly sensational plant.  It has great stature, texture, and mass-there is no missing it.  The red violet and lime yellow coleus Arizona Sunset repeats that dark foliage color in a different hue, and leavens it with lime.  The delicate and pale lavender petunias are a sharp contrast-all of that lavender brings out the purple in the canna leaves.  The flowers have all but obliterated any view of its green foliage.  

This centers of these canna leaves appear green when the sun shines through them. This made it fine for me to plant an olive green coleus with a red violet obverse next to it.  The red thread leaved alternanthera appears to darken as it matures-a large mass of red leaves traps light, rather than reflecting it.  The pink petunias and creeping jenny define the lower edge of the alternanthera mass.  Very dark foliage benefits from some lighter company-any other color than medium green, please.

Malabar spinach has very dark green leaves which are red violet on the reverse side.  The stems and knobby flowers are also dark red violet.  Though I love how it climbs to great heights in just one season, I also value that dark foliage.  Persian Shield and black sweet potato vine mirror that color quite well.  This pot was dark up 12 feet into the sky, and just as dark, down to the ground.  This made me think a big button of green-foliaged Red Sun zinnias would work.  

The very dark purple oxalis triangularis is one of my favorite plants.  That rich dark red violet leaf-so beautiful.  I especially like it with Solenia orange begonia.  Very little of the green leaves of the begonia are visible-this is a study in orange and dark red violet.  The varigated licorice is not your garden variety green-it looks as fresh as the description mint green suggests. The big idea here-should you choose to include dark foliaged plants in your landscape, garden, or containers, pay even more attention to the color you put with them.
